ROG Thor 1200W Platinum Random Restarts

[Diligence]

Hi,

I hope all of you are doing well.



I have a problem with my computer randomly restarting. It doesn't crash, it just restarts. It can happen while playing games, while idling on the desktop, while running benchmarks, watching YouTube videos,....etc. There are no minidump files either. I managed to stop the issue from happening but the fix doesn't make any sense to me, that's where I need you help. Basically, when I set my GPU power limit to 80% in MSI afterburner, the system is rock solid. Any higher and I experience random restarts. I know this is a potential power issue, but I don't know how to resolve this because I already swapped the PSU to a ROG Thor Platinum 1200w as that is one of the highest tier of PSUs available where I live and the power draw on the OLED screen doesn't go past 600 watts under any circumstances. I also used two 8-pin cables from the PSU instead of using a branched cable. My PSU has hybrid fan control and if I keep the fan on, the restarts are lessened but not eliminated I also noticed that the back of my case lights up the lamp on my tester screwdriver. The casing of the PSU doesn't light up the tester screwdriver, nor do any of the other steel panels on my case. I don't know if that has any significance but I thought I'd mention it anyway.

One possibility is that card might simply not be stable at factory settings.
It's possible that even during low load GPU goes momentarily to high clocks.

Though would certainly recommend new clean OS install instead of upgade over upgrade.

Also try limiting parts to minimum just to see if there's change.

And monitor chipset temperatures.
X570 chipset cooler designs of Asus are straight from anus of marketing and unless you have air conditioning, you propably have rather warm room temperature to start with.

Chipset temperatures improved actually compared to my X570-E Gaming. Now, they never pass 70C and that's the maximum reading in HWiNFO

is your 5950x and RAM stock?

Yes, just PBO on Auto and RAM at the D.O.C.P settings



Something I forgot to mention is that sometimes after the initial random restart, it would restart while loading the OS. On rare occasions it would restart more than once.

I was actually blaming the OS as well but everything went crazy when I installed Windows 11 on my 1TB 870 EVO. During the initial Windows setup, the screen would go black and the keyboard lights would shut off. Then, all the fans in the system would go full tilt, except the GPU fans. The power button becomes totally unresponsive and the only way to turn off the system would be to flip the switch at the back of the PSU. The system also restarted with the newly installed Windows 11 before installing the GPU drivers. So, weirdly enough, I don't think it's the GPU

It's not a crash, the best description would be like somebody hitting the reset button.
