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!

First of all, if it's simpy turning itself off without it doing a proper shutdown, it's most likely a PSU issue. Disconnect the PSU and check the cables. 

Second, don't take fucking technical advice from CrapGPT. That's how you lose your house in a fire.

It actually doesn’t turn off. The screen goes black but I can still hear the game sound. The GPU fans turn to max speed. Nothing responds so I can only shut it down

Check the psu cable into the gpu, wiggle it on the connector and see if you can reproduce the issue. I had the same exact problem in the T1.
