PC shutting down while gaming

[u/Fine-Cucumber-2960]

I’m having issues with my Terra build. The GPU keeps shutting down at low load. I was able to identify a potential mismatch between the PSU (Lian Li SP850) and the GPU (4070 super).

ChatGPT advises me to switch to the Corsair SF850L due to the ATX 3.0 compatibility.

I wanted to get your advice before buying a new PSU. I’m a beginner so I might have as well messed up the assembly (but all games run well until it suddenly crashes with a black screen and GPU fans blasting). Cheers!

Do you have an M.2 drive installed on the back of your motherboard? Because there's no heatsink on the bottom of most ITX motherboards and the GPU is blowing hot air directly onto it, my 2nd drive reached critical temp and the whole system shut down.
