Random Power Downs Under Load (while gaming)

[EDSman11]

So I just finished a new build and I am running into an issue where my PC turns itself off under load. No BSOD or anything, it just powers down and stays off (no auto restart). I play a significant amount of Escape from Tarkov and the shut downs only seem to occur after a couple hours of playtime. At first I thought it may be an overheating issue, however, I had HW monitor running while playing and my temps seemed to remain between 75-80 C on the CPU. Running Prime95 for ~10 min yields temps on the CPU of roughly 90-95 C, however, the system doesn't seem to experience the power down issue. Because of this, I'm thinking its either a GPU or PSU issue. I cant imagine that the system is drawing more than 750 watts though right? Is there anywhere I can find a dump file that would give me any hints as to the cause of the power down?

 

Any help is greatly appreciated!

Any PSU clicks?

I'm not 100% certain but it powers off just as if the pc had completely lost power. It boots up fine immediately after, but hopping back in game results in a power down usually within 5-10 minutes (rather than the initial 2-3 hours).

Could you check if the PSU clicks on the shutdown, studden shutdowns like that are usually PSU problems.

It does make a click (pop) noise along with the high pitched noise of the fans winding down, however, it makes the same noise when I shut the PC down normally through windows.

Can you record it?

Sure, I'll try to get it to happen and see if I can catch it on video.

Event viewer will say kernel power. Sounds like PSU shutdown pop. Probably the RTX 3080 power spiking. There are ten posts like this a day maybe there should be a sticky post about it

I ended up resolving this by doing a simple bios update. The bios version I was on was F31q (Release Date: 12/18/2020). Updating to F31 (Release Date: 12/31/2020) fixed the issue completely. Must have been a stability issue with the new 5000 series processor. Also worth noting the version of the bios I was running previously (F31q) is no longer available on gigabyte's website.
