For several months I faced an issue: under heavy load my PC would simply shut down; no BSOD appeared, only a power-off and restart. This mostly occurred during video editing, though it also happened occasionally when searching the event log I found 41 error codes.
Attempts to resolve included reducing the GPU's power by 8-10%, which temporarily helped but led to frequent restarts. Even after lowering the GPU voltage to 25%, restarts continued, especially during video editing sessions.
I also changed the power cable, suspecting it might not be providing sufficient power from the previous unit. Trying different GPUs didn’t change the problem—an RTX 2060 6GB worked just fine, while a GT 1030 did not.
I suspected the power supply unit could be the root cause, as it seemed capable of handling my system’s requirements, but I couldn’t test another one. Recently, I considered the possibility that the motherboard might be involved, though I haven’t managed to verify this yet.

What's the age of this PSU in your setup?
I installed it last summer, around a year ago.
I've used different GPUs before; the same happened with an RTX 2060 6GB, but it worked well with a GT 1030.
You might want to consider getting a more reliable 750W PSU from a trusted source and powering your system. The problem you're facing wasn't with the GPU or setup, it was definitely with the PSU itself.
