Arc A750 PCIE Power supply problem

[Han_Walker]

Hello, I recently purchased an Arc A750 reference graphics card. I plan to install it in the second PCIe x16 slot on my motherboard to build a dual-graphics card system. However, since many motherboards on the market do not provide a PCIe 8-pin auxiliary power connector, I would like to ask whether the A750 can operate stably with only its 8+6 pin power connector when there is no auxiliary power, meaning the motherboard only has a 24-pin power connector for the CPU and the motherboard. Thank you in advance for your response.

Hello Han_Walker,

Thank you for posting in Intel community Forum.

For me to better understand and diagnose the issue further, let me ask you to provide detailed responses to the following questions. This information will help me isolate the problem and determine the most appropriate course of action moving forward.

1. May I know why are you going to set up a dual GPU system?
2. Does your power supply has an additional 8-pin cable?
3. What is the wattage of your power supply?

If you have questions, please let us know. Thank you.

Best regards,

I plan to use a 9070XT as my primary gaming GPU, and an A750 as my secondary GPU for streaming. I haven't purchased the power supply yet, but rest assured, I will choose a 1200W or higher power supply with multiple 8-pin connectors to meet the needs of this system.

Hello Han_Walker,

Thank you for the update.

Let me share some links regarding your set up and power supply:

Does Intel® Arc™ Support Multi-GPU?

Intel® Arc™ Graphics – Desktop Quick Start Guide

As per the second link, for Arc if it is the only Graphics controller. It requires 600 W and PCIe 8-pin cable to power the card.

If you have questions, please let us know. Thank you.

Hello Han_Walker,

I hope this message finds you well. 

Let me just add that the earlier link regarding: Does Intel® Arc™ Support Multi-GPU? tackles SLI and Crossfire like configurations. your proposed configuration may work in consideration that ample power supply is being supplied to the system.

Regarding PSUs that can work with your setup, our Intel® Authorized Distributors are fully trained on our products and will be able to provide pricing information and answer any questions you might have related to PSUs that can work with your setup.
