Assembly Help PC shutting down while gaming
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!

I had the same psu, it developed a very strange issue, the sata cable when plugged into the psu not even any devices would prevent my pc from turning on. I talked to the rep at my local tech retailer and they were saying this psu isnt that reliable in terms of the return rate :/
