Intel Arc A750 LE — Peripherals cut off during importing videos on Premiere pro, and specific games

CapTainN · ‎08-30-2025

Background (First Issue: Freezing/Buzzing Sound)

I’ve had an ongoing issue with my Intel Arc A750 LE GPU for months, during which I've experienced screen freezes and buzzing/robotic sounds in certain games. The freezes would last for about 7–8 seconds. After that, a buzzing/robotic sound occurs, and everything goes back to normal, like nothing happened, then the game continues running as normal. I first encountered this issue with newer drivers.

Solution: The only way to fix this at the time was to roll back to an older Arc driver, the driver version is 32.0.101.6734. This resolved the freeze and buzzing problem. I’ve been using this stable version for 2 months.

New Problem (Peripherals Losing Power)

Probably on 16th August, a new issue came up:

When importing videos into Adobe Premiere Pro (I use it for personal work), my monitor, keyboard, mouse, and microphone would instantly lose power. The PC stays on, but I need to force shutdown by holding the power button or toggling the PSU switch.
In Marvel Rivals, specifically when I view the Abyssal Flame legendary skin animations (Winter Soldier, Cloak & Dagger, or Venom), the same issue happens: peripherals lose power.

What I’ve tested (Troubleshoot):

1. Storage & Location Testing

Installed Premiere Pro and Marvel Rivals on HDD:
- Premiere Pro worked fine without the peripherals issue (while importing videos).
- Marvel Rivals still caused the issue (peripherals cut off).
Installed on SSDs (both NVMe):
- Premiere Pro always causes peripherals to cut off (during imports).
- Marvel Rivals (installed on SSD): The same issue (peripherals cut off during animation viewing).

2. Testing SSDs:

Freshly installed genuine Windows on both SSDs to rule out SSD-specific issues.
Doesn’t matter which SSD I boot from; if Premiere Pro or Marvel Rivals are installed on SSD, the issue persists.

3. RAM testing:

Corsair Vengeance dual-channel (8×8 GB).
- Single stick (8 GB):
- - No issue with Marvel animation (peripherals don’t cut off).
  - Still cuts off peripherals when importing videos into Premiere Pro.
- Dual Channel (16 GB):
- - Marvel animation causes peripherals to cut off.
  - Premiere Pro importing causes the same issue.
Tested with XMP off and enabled, no lasting resolution.

4. Stress Testing:

Unigine Heaven: Tested with Ultra settings, no crashes or issues during the test.
Cinebench: Ran both single-core and multi-core stress tests, all results were stable with no temp issues or crashes.
FurMark: Ran a 30-minute test at 4K resolution with 8x anti-aliasing and Ultra settings. GPU usage stayed 91-92%, and the max temperature was 71°C. No issues or power cutoffs during the test.

5. Windows & Event Logs

After multiple forced shut down, and booting during the tests, the BIOS displayed an fTPM error when peripherals shut down, prompting me to reset TPM settings.
Event Viewer showed nothing useful, even after the issue occurred. But if needed, I can provide it.
Windows Updates: I’m aware that there’s an issue with update KB5063878, which has known problems causing freezing and SSD failures. I’ve excluded this update from my system.

6. Browsers and Artifacts:

Microsoft Edge and Discord:
- Hardware acceleration in both programs caused graphical artifacts (box trails and weird redraw glitches).
- Disabling hardware acceleration fixed these artifacts in both Edge and Discord.

Note: I was on vacation for a while and came back on August 29th. I saw there was a new version, 32.0.101.7026 (WHQL Certified), and installed it. I also noticed there was an update for Marvel Rivals (Steam). After that, it seems like the issue with the game was fixed, and the same animations no longer cause any problems. I have watched the animation multiple times, and everything was working fine.

Symptoms Recap (Current State)

Marvel Rivals skin animations (previously causing peripherals to lose power) no longer cause this issue after the latest updates.
Premiere Pro still causes peripherals to lose power when importing video files or using default templates. The only solution for this problem is using IGPU (5600g).
With the newer driver, I still experience the “freeze + buzzing” issue during gaming, but it resumes normally after a few seconds as soon as the buzzing/robotic sound occurs.

What I Need Help With

Why is this specific issue affecting me with the Intel Arc A750 LE, but not other Arc users?
Is this something that future driver updates can address? If so, can Intel provide guidance on a potential driver fix or beta versions for testing?
Any insights on what might be causing the peripherals loss on imports in Premiere Pro, and if this could be a driver/compatibility issue with Arc?

Hi CapTainN,

Thank you for reaching out regarding the complex issues you're experiencing with your Intel Arc A750 LE GPU. I truly appreciate the incredibly detailed troubleshooting documentation you've provided - your systematic approach to testing different configurations, storage types, RAM configurations, and stress testing shows exceptional thoroughness in isolating these problems.

I understand how frustrating this must be, especially dealing with multiple interconnected issues: the original freezing/buzzing sounds in games, the peripherals losing power during Premiere Pro imports, and the Marvel Rivals animation issues. It's encouraging to hear that the latest driver update (32.0.101.7026) has resolved the Marvel Rivals problem, but I recognize that the Premiere Pro issue persists and is significantly impacting your workflow.

Your testing methodology has provided valuable insights, particularly the observation that the issue occurs with SSD installations but not HDD for Premiere Pro, and the RAM configuration differences affecting the Marvel Rivals animations. The fact that stress testing tools like FurMark, Unigine Heaven, and Cinebench run without issues suggests this may be related to specific software interactions rather than general hardware stability.

To better assist you with these driver-specific compatibility issues, I need to gather some additional information:

What version of Premiere Pro are you currently using, and have you tried disabling hardware acceleration in the Premiere Pro settings?
Which specific video formats/codecs are you importing when the peripheral issue occurs (H.264, H.265, ProRes, etc.)?
Does the peripheral power loss happen instantly upon starting the import or after a certain duration?
You mentioned the issue started around August 16th - did you install any Windows updates, software, or make system changes around that time?
Since you mentioned fTPM errors, have you tried disabling TPM entirely to see if it affects the issue?

If possible, could you provide a short video clip showing the peripheral power loss occurring during a Premiere Pro import? This visual documentation would be extremely helpful for our engineering analysis.

For faster communication and to discuss these technical details more efficiently, I'm available for a phone call. Please let me know a convenient time for you, and I'll ensure we connect promptly to dive deeper into these issues and work toward a comprehensive solution.

Your detailed documentation will be invaluable for our investigation, and I'm committed to helping resolve these compatibility concerns with your Arc A750 LE.

Hello,

Thank you again for taking the time to help me troubleshoot this issue. I really appreciate it.

I also contacted the Marvel Rivals dev team before and shared all the details, so if the issue was game-related, they could address it on their side. Since the recent game update and the latest Intel driver, the Marvel Rivals animation that was causing peripherals to lose power seems to be resolved.

Now, about your questions: If the original issue was triggered by something installed around August 16th, I’ve now done a fresh installation of genuine Windows a few times already, so it’s unlikely to be relevant anymore.

Regarding Premiere Pro, I’m currently using version 25.2.3 (Build 4). Before disabling fTPM, I tried disabling hardware-accelerated encoding/decoding on media, because in Project Settings → General → Mercury Playback Engine GPU Acceleration (OpenCL), the option is locked and cannot be changed. However, disabling encoding/decoding alone did not fix the problem.

After disabling fTPM, importing standard videos (H.264), PNG/JPG images, and audio files no longer causes my peripherals to lose power. However, I discovered that animated WebP files (similar to GIFs) still trigger the peripheral power loss instantly, while still image WebP files import without issues.

At this point, it seems that either the Marvel update, the Intel driver update, or disabling fTPM resolved the majority of the issue, but the animated WebP problem remains. I wanted to make sure you have all the details I gathered.

Additionally, I’m not sure why this started happening suddenly. I’ve been using this Arc A750 LE GPU for about two years without issues with the latest driver versions. The freezing and buzzing sound problems began in the last 2–3 months, and new drivers used to give me lower FPS on games. I solved that issue by sticking to the older stable driver version 6734. Here’s an FPS comparison I did a month ago:

NFS Unbound (Ultra) → 6734: ~60 FPS (smooth) | 6987: 30–38 FPS (laggy)
Marvel Rivals → 6734: 100+ FPS minimum | 6987: 30–60 FPS + random 8–10s freezes (Per game session)

However, the new peripheral power-loss problem that began around August 16th has been much more disruptive. Neither my stable driver nor the latest drivers helped until version 32.0.101.7026.

My questions now:

Premiere Pro seems to work for now, and I only tested h.264, PNG, JPG, and MP3, finding an issue with animated WebP. What if I encounter similar issues with other formats in the future while importing? For now, should I just avoid animated WebP files? When is this expected to be fixed?
Since the latest drivers previously caused game freezes, even including the one I'm using currently, how can I prevent this from happening again if a new driver causes similar issues?

Thanks again for your support.

DeancR_Intel · ‎09-01-2025

Hi CapTainN,

Thank you for the comprehensive update and for your continued patience in working through these complex issues. I'm pleased to hear that the combination of the latest driver (32.0.101.7026), Marvel Rivals game update, and disabling fTPM has resolved most of the peripheral power loss problems you were experiencing.

Your detailed testing has provided valuable insights, particularly the discovery that animated WebP files still trigger the peripheral power loss while static WebP files import without issues. This specific behavior pattern is very helpful for our investigation.

Before I proceed with the internal investigation, I need to gather some additional documentation to ensure we have complete information for analysis:

Could you please provide a System Support Utility (SSU) report? This will give us detailed information about your current system configuration and driver status.
If possible, could you provide a short video clip or photo showing the peripheral power loss occurring when importing animated WebP files in Premiere Pro? This visual documentation would be extremely helpful for our engineering analysis.

Regarding your questions about animated WebP compatibility and driver stability concerns, I will address these thoroughly once I have the additional documentation and can proceed with the investigation.

For now, I would recommend continuing to avoid animated WebP files as a temporary workaround while we work on understanding this specific compatibility issue.

Thank you for your thorough documentation and patience. Once I receive the SSU report and visual evidence, I'll be able to investigate these compatibility concerns more effectively.

Hello,

Sorry for the late response. Here is the SSU report and the video footage you requested. Please note that the video was recorded about a month ago. At that time, the Marvel Rivals devs also asked me for footage, so I created the video then. I’m sharing it now so you can better understand the issue occurring in Premiere Pro.

All this time in Premiere Pro, when I import something, the peripherals don’t cut off instantly. After the import, it usually takes a few seconds before the issue occurs. Sometimes, it can happen after 2–3 imports, but it's rare. As I mentioned before, after tweaking the BIOS by changing PCIe from Auto to Gen 3 and disabling fTPM, right now only the WebP format is causing this problem. So far, I can import both videos and images without issues (last time I checked).

I also recently experienced peripheral power loss again while playing Marvel Rivals. This time it wasn’t triggered by watching a character animation. Instead, it happened during an ongoing match. I was playing normally with my friends when suddenly all of my peripherals lost power, my monitor went black, and I couldn’t hear my teammates. I had to force shut down my PC and boot it up again.

After restarting, I tried one more game session with them. That time, the issue did not occur. It’s worth noting that when I mentioned the “ongoing match,” it was on a completely new map where the peripheral loss happened. In the second session, I didn’t get that map, so I’m not sure if this is map-specific or not.

Since my last reply, this peripheral power loss has only occurred once while playing Marvel Rivals, and I’ve been avoiding using Premiere Pro for now. However, it’s not possible for me to avoid it forever, so I really hope we can find a solution for this issue.

For everyday use like browsing, watching series/movies, the PC runs fine, but I’m concerned the problem will return if I launch games like Marvel Rivals or Premiere Pro again. Also, in other games, I still get random freezes and a sudden buzzing sound in per gaming session. I’m not sure whether this is a GPU hardware issue or a driver issue. There is no physical damage in any components including my GPU.

Thank you for your support, and I look forward to your guidance.

Hi CapTainN,

Thank you for providing the SSU report and the detailed video footage. I appreciate your patience and the comprehensive documentation you've shared throughout this troubleshooting process.

After reviewing your case details, I can see that you're experiencing complex issues with your Intel Arc A750 LE that manifest in specific scenarios - particularly with Premiere Pro imports (especially animated WebP files) and occasionally during Marvel Rivals gameplay. Your systematic testing approach has been invaluable in isolating these issues.

The fact that:

Stress tests like FurMark run without issues (consistent load)
Problems occur during specific software operations (variable/spike loads)
fTPM errors appear in BIOS after power loss events
Issues are resolved temporarily by BIOS changes (PCIe Gen 3, fTPM disable)
Animated WebP files still trigger peripheral power loss while static WebP files work fine

This pattern provides valuable insights into the specific nature of these compatibility issues.

I will be checking this case internally with our engineering team to analyze the driver interactions with Premiere Pro and the animated WebP compatibility issue. The video footage and SSU report you've provided will be crucial for this investigation.

I'll get back to you soon once I have more information from our internal analysis.

In the meantime, please continue avoiding animated WebP files in Premiere Pro as a temporary workaround.

I have been avoiding Premiere Pro and Marvel Rivals for a while, so I wanted to play Wuthering Waves since I had some free time today. Within the first minute of gameplay, my PC froze as usual, produced the same buzzing/robotic sound I mentioned earlier, and then recovered.

After about 5 minutes, I moved to a new location and then changed some graphics settings, specifically enabling XeSS (Ultra Quality preset). I used to play this game on Ultra settings before without any issues. As soon as I resumed the game, all peripherals instantly lost power, while system fans and LEDs remained on, exactly like the Premiere Pro issue.

Here’s what I tested afterward:
1. Disabling XeSS and Frame Generation → peripherals still lost power instantly.
2. Lowering preset to Ultra Performance → same issue occurred.
3. Event Viewer shows no errors or warnings at the time of the cutoff.

For reference, I’m still running in Gen 3 mode, and have already disabled fTPM as discussed earlier.

At this point, I’m starting to believe my GPU may actually be faulty because other Arc A750 users do not have the same issue. Do you recommend I request an RMA/replacement?

DeancR_Intel · ‎09-07-2025

Hi CapTainN,

Thank you for the additional testing and detailed feedback regarding your Intel Arc A750 LE issues. I appreciate you taking the time to test Wuthering Waves, and I'm sorry to hear that the peripheral power loss problem has now extended to another game. I've been reviewing your issue internally and need to gather some additional information to help us better understand the root cause of the peripheral power loss and system instability you're experiencing.

To further investigate these issues, I need to check a few more details about your system configuration and thermal behavior:

Are you experiencing any overheating issues with either your processor or graphics card during normal operation or when the peripheral power loss occurs?
Could you please provide the exact thermal readings you're seeing on your system? Specifically:
- CPU temperatures during idle, normal use, and when issues occur
- GPU temperatures during idle, normal use, and when peripheral power loss happens
- System temperatures during Premiere Pro animated WebP imports
- Thermal readings during Marvel Rivals gameplay when issues occur

This thermal and overclocking information will be crucial for our engineering analysis, as it may help explain the specific power delivery patterns and system behavior you're experiencing with the Arc A750 LE.

Best regards,

Just to clarify, before my vacation, the main problem was peripheral power loss, and it only happened when I tried to import anything into Premiere Pro or while watching specific character animations in Marvel Rivals.

But after my vacation, I updated both my GPU driver and Marvel Rivals, and it seemed like the Marvel issue was fixed. I tested Marvel Rivals with both the latest and older Arc drivers, and the issue did not occur.

I’m currently back on the latest WHQL-certified Arc driver and have been using it since. As I mentioned, I can now import tested formats like MP4 (H.264), MP3, JPG, PNG, GIF, and static WebP without any issues. However, importing animated WebP files still triggers peripheral power loss.

Additionally, while playing games, it seems a specific MAP AREA triggers peripheral loss. For example, in Wuthering Waves, the issue only happened in one specific map area. Lowering the super-resolution setting to ‘Quality’ fixed the issue at that time. Later, I set super resolution back to Max Quality but avoided that affected area, and during a 30-minute test session at max settings, I didn’t experience any peripheral power loss. However, I believe going back to the affected area might trigger it again. Note that I still get game freeze + buzzing sound in each gaming session at least 1/2 times.

Most importantly, my PC stays on all the time, even when I’m not using it, and I never experience peripheral power loss unless one of the events I mentioned above occurs.

As you asked, there are no overheating issues with my PC. I’ve attached two screenshots of CPU and GPU temperatures from HWMonitor. The readings were taken after playing Wuthering Waves for 20 minutes, followed by 10 minutes of idle time before capturing the screenshots.

To summarize: the peripheral power loss always happens when importing animated WebP files, and in some game-specific areas, regardless of whether the system is idle or under heavy load. Nothing seems to prevent it.

DeancR_Intel · ‎09-09-2025

Hi CapTainN,

Thank you for the comprehensive update and the detailed thermal screenshots from HWMonitor. I appreciate your thorough testing and the clarification about the specific conditions that trigger the peripheral power loss.

Based on your latest testing, I can see that Animated WebP imports in Premiere Pro still cause peripheral power loss.

Given the complexity and specificity of these issues and considering that standard troubleshooting methods have not provided a complete resolution, I will be investigating this further internally for further checking and get back to you once the information you need is available.

Hi CapTainN,

Thank you for your patience as I continue to investigate the peripheral power loss issues you're experiencing with your Intel Arc A750 LE.

Based on my internal review of your case, I need to request one additional diagnostic test to help us better understand the root cause of the peripheral power loss events.

To help isolate whether this issue is related to power delivery or the discrete graphics card specifically, I need you to perform the following test:

Integrated Graphics Testing:

Power down your system completely
Safely remove your Intel Arc A750 LE graphics card from the PCIe slot
Connect your monitor to the motherboard's integrated graphics output (your AMD Ryzen 5 5600G has integrated graphics)
Boot the system using only integrated graphics
Test your normal usage patterns including:

Adobe Premiere Pro operations (including animated WebP imports if possible)
General gaming or system usage
Any activities that previously triggered peripheral power loss

Please observe whether the peripheral power loss events still occur when using only the integrated graphics. This test will help us determine if the issue is related to:

Power supply capacity under load
The discrete graphics card itself
System-level power management issues

Important Notes:

Take proper electrostatic discharge precautions when removing the graphics card
Ensure all power connectors to the graphics card are disconnected
Your integrated graphics performance will be significantly lower, but this is expected for testing purposes

Once you've completed this testing, please let me know the following:

Whether peripheral power loss events still occur with integrated graphics only
Any differences in system behavior during the same activities that previously caused issues

This diagnostic information will be crucial for determining the appropriate resolution path for your inquiry.

Best regards,

Hi, apologies for the delay in getting back to you, it’s been a busy week on my end. I’ll be running the integrated graphics testing you requested within a day or two and will provide a detailed update with the results shortly after. Thank you again.

DeancR_Intel · ‎09-16-2025

Hi CapTainN,

Thank you for your response, and no worries at all about the delay - I completely understand that life can get busy. I appreciate you letting me know that you'll be conducting the integrated graphics testing within the next day or two.

Your case involves complex peripheral power loss issues with your Intel Arc A750 LE that occur under specific conditions: animated WebP imports in Premiere Pro and certain game areas/settings. We've made significant progress in isolating the triggers, and the integrated graphics test will be crucial for determining whether this is a discrete GPU hardware issue or a broader system power management problem.

The integrated graphics test will help us determine if the peripheral power loss events still occur when your Intel Arc A750 LE is completely removed from the system. This will definitively tell us whether the issue is:

Related to the discrete graphics card itself
A system-level power delivery problem
Power supply capacity under specific load conditions

Once you complete the testing and provide the results, I'll be able to proceed with the appropriate resolution path based on the findings. If the integrated graphics testing shows no peripheral power loss events, this would strongly indicate a hardware issue with your Arc A750 LE that may warrant warranty consideration.

Take your time with the testing, and please ensure you follow proper safety precautions when removing the graphics card. I'll be here when you're ready to share the results.

Thank you for your continued patience and thorough cooperation throughout this investigation.

Hi Dean,

I’ve completed the integrated graphics testing you requested. Here are my observations:

While using the dedicated Intel Arc A750, peripheral power loss occurred again while playing Wuthering Waves. As mentioned earlier, this issue tends to occur with high settings and when Super Resolution is set to Ultimate quality+, which significantly increases the GPU load. In this game, the peripheral power loss seems character animation (When you get a character from pulling) and map-specific.

This time it happened in a crowded place and didn’t even give me a chance to change the Super Resolution to “Quality” for minimal GPU load. The moment my game loaded, it triggered the peripheral power loss instantly.

During this test, I noticed something unusual. I removed my case’s tempered glass and back panel, and right at the exact moment the peripherals lost power, I heard a distinct “chik” sound from inside the PC. After repeating the test several times, it became clear that the sound was coming from my PSU. Every time the peripherals cut off, the PSU made this noise.

When I switched to my iGPU (Radeon graphics) and repeated the same tests:
1. Adobe Premiere Pro imports (including animated WebP)
2. General usage
3. Wuthering Waves gameplay (same crowded area)

Everything worked without issue. No peripheral power loss occurred, and I was able to move my character to a less crowded area that normally triggered the cutoff with the Arc GPU. Importing animated WebP and other files also worked normally.

When I returned to the Arc GPU, since my character was already in a less demanding location, I was able to continue playing without triggering peripheral power loss. I also set Super Resolution back to “Quality” to keep the GPU load lower, which helped avoid the issue.

One important note: while testing with the iGPU, the PSU was completely silent. But with the Arc GPU, the PSU made the “chik” noise every time a peripheral power loss occurred. The PSU and everything inside my pc kept running as usual, only the peripherals lost power.

One more detail: I’ve attached two images of my Wuthering Waves graphics settings. When set to Quality, the game shows “Smooth” in the load meter and runs fine without issues. But when set to Ultimate quality+, the load meter shows “Laggy.” Despite that, the game actually runs smoothly at 50–60 FPS, and with Frame Generation enabled, it even goes beyond 100 FPS. However, using Ultimate+ consistently triggers the peripheral power loss, which makes me think the problem is less about performance and more about stability under load.

At this point, I am very confused. I suspect that the problem lies either with the GPU or the PSU. Since I’m using a Corsair RM650 (Gold certified, with 6 years of warranty left), I had assumed it would be capable of handling the Arc A750 under load. I would really appreciate your guidance in determining whether this points more toward a GPU fault or a PSU/power delivery issue.

Thank you again for your continued assistance.

CapTainN · ‎09-18-2025

I forgot to attach the images in my last reply. Here are the two screenshots of my Wuthering Waves graphics settings.

DeancR_Intel · ‎09-19-2025

Hi CapTainN,

Thank you for completing the comprehensive integrated graphics testing and providing such detailed observations. Your systematic approach to testing has provided crucial insights into the root cause of your peripheral power loss issues.

Integrated Graphics Results:

No peripheral power loss occurred during any testing scenarios
Adobe Premiere Pro imports (including animated WebP) worked normally
Wuthering Waves gameplay in problematic areas functioned without issues
PSU remained completely silent during all integrated graphics testing

Intel Arc A750 LE Results:

Peripheral power loss continues to occur under high GPU load conditions
Distinct "chik" sound from PSU occurs at the exact moment of peripheral power loss
Issue correlates with high GPU load settings (Ultimate quality+ vs Quality settings)
PSU noise occurs consistently with every peripheral power loss event

Your testing has revealed a critical correlation between the Intel Arc A750 LE under high load and PSU behavior. The fact that the PSU remains silent during integrated graphics testing.

This strongly suggests a power delivery issue when your Intel Arc A750 LE draws higher power under demanding conditions.

While your Corsair RM650 Gold is a quality unit that should theoretically handle an Arc A750 LE, the audible "chik" sound during power loss events indicates the PSU may be experiencing protection circuit activation or power delivery stress under specific load conditions.

Your testing has been invaluable in isolating this to a power-related issue specifically tied to your Intel Arc A750 LE under high load conditions.

I'll check this further and get back to you with findings from my internal investigation and recommendations for resolution.

Thank you for your exceptional patience and thorough diagnostic work throughout this process.

Best regards,

Dean R.

Hi CapTainN,

Thank you for your comprehensive testing and detailed documentation regarding the peripheral power loss you're experiencing with your Intel Arc A750 LE under high GPU load conditions. Your systematic approach to isolating the issue through integrated graphics testing has been invaluable for our analysis.

Based on the available information you've provided, this appears to be a power-related issue rather than a GPU defect. Here are the key indicators that support this assessment:

Critical Evidence:

PSU audible "click" noise coinciding with power loss events indicates activation of the PSU's safety/protection mechanism via relay switch
Selective power loss pattern where peripherals shut off while the PC remains operational, suggesting isolated 5V rail disconnection
Load correlation where Quality settings work fine but Ultimate+ settings trigger power loss

Supporting Evidence: Your intensive GPU testing results actually rule out the GPU as the primary cause:

FurMark stress test: 30-minute run at 4K resolution with 8x anti-aliasing on Ultra settings
GPU utilization: 91-92% sustained with peak temperature of 71°C
Result: No power interruptions or issues detected

The absence of issues during integrated GPU operation (due to minimal power draw) further supports a power-related cause rather than a GPU hardware defect.

Given the potential power system involvement, we advise against additional stress testing on the current configuration to prevent possible hardware damage or property hazards.

Next Steps Required:

PSU Replacement Test:
- Try an alternative power supply (650W minimum) to isolate PSU-related causes
- This will help determine if your Corsair RM650 Gold is experiencing protection circuit issues
Complete System Diagnostics:
- Generate full SSU log with "Everything" option enabled
- Your previous log was incomplete for system-level power analysis
- Download SSU from: https://www.intel.com/content/www/us/en/support/articles/000005511/processors.html
Power Event Analysis:
- Execute system power report via Command Prompt using: powercfg /spr
- Provide the generated log file for power-related event review
- This will help identify any power management issues at the system level

Your Intel Arc A750 LE appears to be functioning within normal parameters during stress testing. The issue seems to be related to power delivery or PSU protection mechanisms activating under specific load conditions that affect peripheral power rails.

The fact that your system works perfectly with integrated graphics and that the GPU passes intensive stress tests suggests the Arc A750 LE hardware is likely not defective, but rather triggering existing power system limitations.

Please complete the recommended testing steps and provide the requested logs. This will help us determine whether this is a PSU compatibility issue, power delivery problem, or requires further investigation.

Thank you for your patience and thorough testing approach throughout this process.

Hello, apologies for the delayed response. I wasn’t able to perform the PSU Replacement Test at this time, but I did run another SSU scan with all options included. Since the system didn’t allow me to attach the .html file directly, I’ve uploaded it to Google Drive and attached the link below, along with the other required files.
