Help, PSU won't turn on after leak testing.

post #1 of 13
Thread Starter 
So I've had this rig for over a year, decided it was time to clean out the rads and install new tubing. I start filling it up with coolant, and my psu is jumpered. After like 10 or so instances of flipping it on and off to let the coolant circulate, my power supply won't turn on anymore. I've tried other outlets in my house, do you think my power supply is broken now?

hmmm might be in some type of limp or protection mode.. have you tried letting it sit for 5 minutes unplugged?

How do you have it jumped? If with just a wire or something similar, make sure it is still making good contact. And maybe try a new power cord. I've had one go bad on me and almost bought a new PSU until I tried that cord on a known working PSU and it didn't turn on

I am using the paper clip method green wire to black. I did let it sit for awhile still doesn't work. I'll check it out more but I don't have another power supply to test the cord.

If morencyam's excellent suggestions don't pan out, my guess is maybe the switch broke. Being a mechanical part, it happens. Usually you can feel a physical difference in how the switch moves when it's busted. If the PSU is only a year or so old, it should still be under warranty.

Also, assuming it's the PSU listed in your sig rig, make sure the mobo extension cable is plugged into the PSU nice and snug. Failing that you could CAREFULLY!!! figure out which pins on the PSU itself correspond to the green and black wires, double and triple check that you aren't going to blow it up, and only when you are 100% certain, jumper it directly.

If you have a multimeter that reads continuity you can check your power cable and the mobo cable to see if there are any breaks. Also if you don't have a PSU tester yet, those are pretty handy at times like this.

Most computer monitors use the same style power cord.

Thanks for all of your replies. I don't feel a difference in the switch. I tried a different power cord from my computer monitor, didn't work either. I did have a slight leak but I had towels covering the psu. I tried looking in with a flashlight maybe a drop fell in?

Took it to get tested today, it is in fact burnt out. 2 Gtx 680s ftw and i7 3770k too much overload for it? Not to mention all the pump, lights, and fans drawing power from it?

Nah, the load was fine...it was the turning off and on that killed it.

I have an old 250watt PSU I use for leak testing. I would not be surprised if my PSU burned out from having the power cut repeatedly in a short time even though I have a monster of a PSU. The capacitors really take abuse from that. This little old one doesn't pull much for amps from the wall so it doesn't get too much strain...and back in 1995 they built them pretty beefy.

I will always get after people that will unplug their computer or switch off a power strip as well. They just aren't made to handle that.

For a $150 gold-rated PSU, that shouldn't be an issue. I'm sure the total number of power cycles he put it through were still well within design spec. It sounds like saophen has a very strong warranty claim.
