But yeah, it does seem weird that it causes a spike in PSU load. We both have 850W PSU, and mine’s an 80Plus Titatinum. Both of us have similar types of hardware, even though I have i9-9900K.
I always thought that those crashes are related to overheating from the GPU trying to render too many things. I don’t know how 850W PSU would not be enough for the load.
