Corsair HX620W Squealing

post #1 of 5

SORRY, I MEANT THE CORSAIR HX620W - typo in the title

History:

Had been squealing for a long time. The computer seems to be running and no bulging of the capacitors visible, etc.

See: http://youtu.be/5SnQgfT_Lvc

I use a straw to probe inside the power supply and it sounded like the larger capacitor in the middle. rolleyes.gif

Ordered a new one (105C, 400V, 470uF from Panasonic) and will try to replace it.

Sounds about right idea (trust me on the spec of the capacitor, it is correct)?

Or is it something else that is wrong?

Yeah I've had caps make a frequency that I could pick up, but my father in law in his 60s couldn't. Have you tried to do anything with it? Take a regular pencil with a rubber eraser and tap on it, see if that does anything. PSU is probably going on you if it's old anyways so replacing it would be the best thing to do at this point.

That's coil whine and there's pretty much nothing you can do about it.... try running some demanding synthetics for a while (a few hours at least), see if it makes any difference.

I FurMark at full resolution - no difference?

I have two HD4850 of which one constantly stays at or above 80C even when idle. The other one stays at around 40-45C.

I will replace the graphic card but ...

are you sure it is the coil and not the capacitor? It sounded quite loud when my straw is next to the capcitor but nothing next to any of the coils?

You, of course, can tell better than me what's the source or the noise (you're there)... but that's a strange sound to be coming out of a capacitor.wink.gif
