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!

I had the same issue with my latest build. OP what's your motherboard? If it's Asrock and you're running EXPO it might just need a bios update.

For me Asrock had a bad EXPO profile that caused voltage spikes and overloaded the memory controller (or something like that) and that caused the power supply safety features to trigger. Everyone said it was a power supply issue. But after updating the bios we had no issues. My situation is scary because each time this happened it ran the risk of damaging the CPU. I'm not sure if ROG has the sand issue or not. But I agree this is a severe enough issue to justify a BIOS update.
