PC Shutting off randomly

I've been experiencing (multiple instances of) my pc switching off completely when playing PoE2.
No other games do this on much higher settings, deeming it PoE2-related.
I've tried multiple things to no avail.

I'm on Win 11 23H2 and not 24H2 (Therefore not limited to 24H2 as I've heard people suggest)
I've tried Vulkan and DX12(Default)
I limited my FPS to 60 and lowered my quality settings
I've set CUP affinity for PoE2 to exclude logical processors 0 and 1

My PC is a recent upgrade and doesn't even get to 50% use on anything, so nothing is being stressed or overheated. (7800X3D, 7900XT, 32GB ram)
