You're experiencing issues switching from an FSP 850W power supply to a CM V850. The machine starts up with the FSP but fails to boot with the V850, showing signs of instability—clicking fans that shut off immediately. You suspect a compatibility or power delivery issue between the PSU and motherboard. Your current setup uses a B450I Gaming Plus AC.

No, I did not replace all the cables before testing the CM V850.

I rely solely on the new cables from the CM, including the power cord. I've also experimented with changing between the 8-pin CPU and 4+4 pin CPU cables.
