ARC A770 - Computer Power Reset @3D game start

[Jlans]

Issue: computer loses power then auto restarts when trying to play any 3D graphics.

ARC A770 boots windows 11 64bit 2H22 no issues.

2D games or video run fine. boot up fine.

Any 3D games run, it turns off the computer & reboots immediately when any 3D graphics start. 

I got lucky one time. ran Risk (2D game). Then ran Hot wheels unleashed (video into and 3D)...3D ran. Rebooted. Ran unleashed again and immediate crash

System:

Prior removed Nvidia 1050Ti(plus all drivers removed).

ARC A770 installed + drivers 4091 and now Beta 4123. Both tested/crashed. Beta in currently

MB: MSI Z690-P DDR4

PWS: OCZ ModXSTREAM-PRO 700W

CPU: Gen 12 I3 12100

Memory: 3200 XMP Teamsgroup 16GB

Resizable BAR confirmed active/enabled (on ARC Control & BIOS)

Note as well, on boot up it asks every time for approval for intel arc control...annoying.

I wanted to come back and give everyone some info on my prior ARC issue where it would shutdown/restart only when starting a 3D game (2D was ok).

I traced the issue to power supply.

Please note the prior power was perfectly fine (was running prior a 1050TI with OZ 700W power supply...ran no issues).

unfortunately I had to return the arc 770 before finding this out. 

but I tested a 3060 and a RTX similar. Both produced same crash issue.

I then bought a newer power supply Thermaltake Toughpower GF A3 750W.

....and the issue went away.

Thx, this is some serious help, mate. Not like the otherone, the troll boy.

I really appreciate it and ordered a new PSU.

Hope it helps.

I'm back to confirm that your solution works.

I got me an Enermax Marblebron RGB 850W and the games are running pretty good with my setup.

Thx a lot.
