I've done a lot of searching, and nothing has helped so far. So, here's the issue:
Today, while playing some Borderlands 3, my entire PC lost power. At first, I thought it may be that I tripped a fuse, or that there was an outage. However, my monitor and other electronics in the room still had power.
I went to go power my PC back on, but it wouldn't start. The MOBO lights were all off - no power at all to anything in the case. I flipped the PSU switch from ON to OFF, then back to ON again, and my MOBO lights came back on. I rebooted the PC with no issues.
5 minutes later, the PC shuts down again - no blue screen, no warning, just complete loss of power. All MOBO lights and LEDs are gone. Same thing - flip the switch, MOBO lights come back on, turn PC back on.
So now I start troubleshooting - is it heat? Is it the CPU? Is it the PSU? I run some stress tests using IntelBurn on the CPU. Several times the PC lost power again, but at no regular interval. Once it was when the CPU reached 80C, another time it was when it was only at 60C. Twice it happened under 100% load, twice it happened under no load at all.
So now I am at a loss. Is there something I'm missing here? Is my PSU done, is this common for when one dies?
PSU: Corsair AX 1200
CPU: i7 7700
GPU: EVGA 1070
MOBO: Asus Strix B250
