[SOLVED] PC turning off on its own when I play games

[DeplorableEnd]

As the title says my PC has been shutting off randomly when I've been playing War Thunder, no clue why its just that game out of all the ones I play. I was trying to see what caused the shut off in event viewer and its Kernel-Power Event ID 41. I've ran benchmarks and never had it crash and all my temps are fine so I am assuming my power supply is messing up? Is there any way to verify that's what it is before I spend all that money on a possible fix?

Thank you in advance for any help or advice!

You didn't list model name of your PSU.

When system is shutting down under load, this usually is because of overheating or PSU protections kicking in.
Your system requires a good quality minimum 750W PSU. That is, if you have single RTX 3080 in your system.

You listed RTX 3080 two times. If that means, you have 2 of them installed, then this requires 1100W - 1200W PSU.

So sorry i thought it was in the spec list somewhere its a
EVGA SuperNOVA 850 GA, 80 Plus Gold 850W, Fully Modular

Also, no I dont have two GPU's I dont know why the software listed two when I got the read out

It's the PSU. EVGA GA is known to have issues with RTX 3080. https://forums.evga.com/PC-Suddenly-Restarting-EVGA-SuperNOVA-850-GA-Issues-With-3080-m3194797.aspx Avoid EVGA except the Supernova G6, Ps and Ts. Or get a good PSU from another brand like Corsair RM850x, Fractal Design ION+ 860w, Super Flower Leadex III Gold 850w/V Pro Gold 850w or XPG Core Reactor 850w.
