Question PC Turning Off (Possibly Overheating)

[ClickMeFish]

Over the past week my PC has been randomly turning off, this doesn't only happen when underload sometimes it happens when I am just watching youtube. Looking at my temps my GPU is normally staying below 40c when not under load and below 70c when under load, cpu is normally below 50c when idle and around about 70c when under load. At this point i'm unsure if its my PSU overheating or something else, I don't have a good way of checking my PSU temp however feeling it with my hand when my pc shuts off, it doesn't feel any hotter then it normally does at any other point. Any help with this would be greatly appreciated.

Welcome to the forums, newcomer!

Extras: 9 120m Case Fans, AIO
Make and model of the case, the make and model of your fans and their orientation? Make and model of your AIO?

PSU: Corsair RM850x
How old is the PSU in your build?

Mobo: ROG B550-F
BIOS version for your motherboard?

You might want to source(borrow, not buy) a reliably built PSU(similar to your current unit) with slightly more wattage at the entire system's disposal to see if your PSU is at fault.

Little update here: I did some testing on my PSU and figured out it wasn't overheating but somehow the power switch on it was going too far into the on state to the point where it was turning itself off. Corsair is replacing it under warranty so the issue should be fixed.
