The power supply is 2024 newest version of NZXT C850 modular power supply.
Cause of damage: I connected EVGA molex cable to the Sata port and test it with a ATX tester. Since the pin out on the EVGA is wrong, result in the 12V pin shorted to the 5V pin, in the 12V back-feeded to the 5v port.
Damage: Power supply shorted out, shut off itself internally, damaged the 5v or 3v rail or the monitoring circuitry. The self protection circuit shut off the power supply when power up because it detected some abnormal/defect. I waited a few minutes, let it self reset then try to re power up. It try to power up, fan spin up but immediately shut of. When turn on the power switch immediately on a 2nd attemp, it no respon at all, the fan not spin up anymore. Waited a few minutes and try it again, the same behavios happen, fan spin up and shut off on 1st attemp only.
