[SOLVED] PC Completely Shuts Down When Gaming

[Kai0261]

When I'm running a video game, after 15-20 minutes of gameplay the PC completely shuts off, out of nowhere. If I press the power button nothing happens at all. I have to flip the switch on the PSU to the off position and then on, and then when I press the power button the PC starts back up. No idea what is causing it, or whether it could be the PSU or GPU. I've tried clean installing GPU drivers but that hasn't done anything to resolve the issue at all.
Specs:
AMD Ryzen 7 5800X
PSU: EVGA SuperNOVA 750 GA
GPU: EVGA RTX 3080 XC3 Ultra
Mobo: MSI MAG X570 Tomahawk WiFi
RAM: 2x16 TridentZ Neo 3200mhz
AIO: CoolerMaster ML240L

This would indicate PSU protections kicking in.
PSU is too weak for your hardware configuration.

Yeah I would assume so. Crazy soon as you mentioned the PSU being too weak I came across another thread with quite literally the same exact issue I'm having with the same hardware as well. For anyone else that might need it:
