Water Cooling Leak: How to Tell if PSU is Okay?

Short version of the story: My water cooling loop sprung a leak (100% my fault) inside my computer. I quickly shut it off, took everything apart, dried it off with paper towels, and let it dry for over 24 hours. I tested my parts with an old 650W PSU I had lying around, and everything seems to be okay! But I'm not really sure about the 850W PSU I was using with the rig when it leaked. Most of the water collected right under the power supply, which was mounted intake-fan-down. It didn't look like a lot of water got in, but obviously it's hard to tell...and there was a pretty big puddle right underneath it.

If I hook up the PSU to a 120mm fan and "jump" the 24-pin cable (like you do when leak testing), it appears to work fine--but how would I know if the power supply is damaged? Could a damaged PSU hurt my other parts if I put the PC back together as it was? Could it be "partially" damaged and work at low load, but have problems once I started pushing it? I don't know much about power supplies and don't want to damage my other parts. Thought maybe someone here knew more or had a little experience with this.

I think you will just have to take a risk on this one TBH.
The only way to test what your concerned about to my knowledge requires something that can draw variable loads and monitor voltage/amps at the same time, which is basically how reviewers test PSU's. This kind of equipment is pretty expensive.

If it works fine jumpered to a fan, I'm inclined to think its fine.

Alright, I'll give it a go then. Hopefully everything works out alright!



Right, this is what I did when I said I tested the PSU. I was worried more about what issues that might not show me.
