Possible PSU problem?

post #1 of 11
Thread Starter 
Hi. Ok I'm probably being paranoid, but I figured It'd be a good idea to see what you guys think.

Just recently I've had some minor issues that I'm thinking might be a dying psu, or maybe the power switch header.

First I noticed that after I turn my computer on then press the delete key repeatedly to enter the bios, I hear a clicking/buzzing sort of sound each time I press the button. Then a few hours later I heard a very faint whining/buzzing sound that promptly stopped (that one sounds like it could be the PSU or maybe coil whine). Now, after plugging a third HDD in to transfer some files after a fresh windows install on an ssd, the computer turns off and then back on before continuing to boot. Considering I'm about to drop in 2 GTX 470s when they arrive in the mail tomorrow is making me more concerned.

What do you guys think? Thank You.

PS: Most of the parts in the computer are 5 months old and newer, including the PSU.

That's very bizarre. To be honest I don't quite know what's happening. I think I'd blame either the power supply or the motherboard. Do you have a spare of either to test on?

Check if your AC cord is loose.

Also, it does no harm to grab a flashlight and peek through the grills of the PSU, just to check for blown/leaking caps, and burnt-out parts.

Sure, the Corsair uses Japanese caps, but everything has a chance of failing, so really, no harm checking.

Try another PSU to see if it still happens.

Unfortunately I don't have another psu to test with. I just find it strange these little things just started happening when I got a new ssd for christmas.

If the buzzing sound is coil whine it could be my MB. This board is known for coil whine but I have C1E/EIST disabled which stops the sound, except when I game (which I wasn't when I heard the sound so that's why I mention it).

And i'll try reconnecting the psu power cable, thanks.

if you are really scared, just rma your psu since it's still under warranty
but it can also be your motherboard. you said keypresses are making the buzz, so it might be a capacitor on the mobo

Oh man, well I just took a look through the grate on the PSU. I couldn't see much but I did some some white gook leaking from a couple of spots, but I couldn't quite tell if it was capacitors they were leaking from (probably a noob statement as I'd imagine thats the only place it would come from)?

So if the PSU was in fine condition I should'nt be seeing any ooze at all right?

White stuff is fine.

That's probably the hot glue they use to secure parts, and also to insulate against cap whine.

A blow cap is one that is bulging, or discharging a brownish liquid.
Also, a PSU with blown caps will have this unmistakeable odour of oil and rust.

Not hot glue; tacky insulation. Hot glue is what Linkworld uses.

Still fine though.
