Some water got into my psu and it popped. It then wouldn't turn on. I found out that if I unplug the 8pin for my CPU it will turn in fine. If I plug it in, the psu shuts off immediately. So I'm figuring that either A. Something in the mobo fried or B. The water somehow damaged the psu in a way that reduced its power output and it can't handle powering the cpu. I'm hoping all I need is a new psu. Anyone have any thoughts or advice about my situation?

If water went in the PSU when it was on and you heard a popping sound...don't use it on anything you care about.

It's possible that other stuff was damaged in the process, but you can't really be sure until you get a good power supply to test with.

If you are sure the water only went in the PSU, your odds of having the damage isolated to the PSU are probably better than 50/50.

What is the brand and model of the power supply unit?

The 8-pin CPU power connector is strictly +12 Volts. Does your power supply have multiple +12V rails or just a single +12V rail?

Graphics cards also draw the majority of their power from the +12V rail(s).

Replace the PSU then go from there
