Computer randomly turning off while gaming

[Kenjionigod]

I've been having this issue with my main computer where my computer is turning off randomly, but only while gaming. I've checked the error logs to try to get some more information, but there's really nothing to go off of unfortunately. Temperatures are totally normal, GPU sits in the low 80s and CPU sits around 60ish. I was also also able to run a Prime95 and Furmark stress at the same time for about 2 hours with no crash. This mainly seems to happen when I'm playing BG3; I played the Sims 4 for hours without a crash, but it's normally within 30 minutes or less that it will just randomly turn of with no warning or BSOD.

 

Some steps that I have already taken; clean install of Windows, removed sleeved cable  extentions, reseated RAM, swapped out RAM, removed GPU Riser card, swapped out the power supply, and swapped out the motherboard. I'm still having issues where it will just randomly turn off, and I don't really know what else to try at this point. 

 

PC Specs:
R7 5800
64GB SP Zenith 3200 DDR4
ASRock B550 Pro SE
Corsair RM850
NZXT z63
RX 6800 XT (With Alphacool Eiswolf 2 AIO)

Any help ideas would be greatly appreciated.

Try using MSI Afterburner to lower GPU TDP% to 80% (default is 100%), that would eliminate the potential for power spiking from the GPU tripping OCP. 850W should be enough, but both RX 6000 and RTX 3000 series high end GPUs were known for requiring an overspecced PSU.

So you have tried

Different RAM

Different Motherboard

Different powersupply

Reloaded Windows

 

You are down to the GPU\CPU at this point.  When the machine turns off is there any information in the windows "system" event log?    There should be an error when the power off happens.     Also does it completely turn off? Fans and everything stop and you just push the power button to turn it back on?  

I would also lead towards the GPU as @Agall mentioneod but 850w should be enough even for the 6800xt spikes with a 5800.  When you tried another power supply was it newer? bigger?

AIB minimum recommended on 6800 XT's is in the 800-850W range, where the problem occurs is the millisecond 200% TDP spikes, which can be a problem for PSUs even as high as 850W. That isn't about a wattage output, but a lack of capacitance/inductance that higher wattage PSUs would have.

I also have a 1000W power supply on hand from when I bought an Alienware during the pandemic; the CPU/GPU were from that build. Everything seemed to be working fine at the time.

The computer just completely shuts off, everything and I'm just left with a black screen. Power button turns it back on as normal. I have an older 3600X on hand that I could use to test, and my other PC has a 6700XT but those are the last two parts that haven't been swapped out. The other power supply I have is a 1000W unit. 

 

As far as logs, there's not much to go off of. The only thing that really sticks out "Event 41" errors, but that just means the computer shut down unexpectedly.

I went ahead and undervolted the GPU in Adrenalin; been playing BG3 for a few hours now without a crash. Honestly, I never even thought about that being and issue but it seems to be stable. I'll keep an eye on it and test some more, but if this is all I needed I'll be happy.
