Corsair CX500 ( builder series version 2 ) watt squealing.

So I purchased 1 Corsair Builder Series Version 2 CX500 watts... I get it and it smells like plastic, hot to the touch (UPS left it out) , and hook it in.. It makes a high pitched squeal soon as I flip it on (as in flip the switch in the back).

So.. I think the heat might have damaged it, RMA it.

The second one does the same thing.

So I'm lost now.

Is it just the PSU? The heat? I hooked the machine up with a 300 watt Bestec I have laying around and it doesn't squeal like an old TV (that heeeeeeeeeeeeeeeeeeeeeee sound).

The only thing that doesn't hookup on the bestec is the second part of the 8 plugin to the CPU (only has a 4 prong connection) so I'm assuming that's not it.

also it can be to do with how clean your power is in your house


I'm refunding it cause it's doing it with the replacement. "how clean my power is" ?

What's a good power supply I should purchase instead for around the same ($60ish) price ?

If you have a PSU tester, you can remove the Corsair PSU
and do this one simple test:

look very closely to see if fan blades are touching
the wire fan grill when the fan blades are moving

One of our Corsair "system builder" PSUs was making
a squealing noise, and I traced it to a slightly deformed
wire grill.

We noticed that the squealing noise only happened
when the PSU was in a normal, upright position,
but the problem stopped when we turned the chassis
on its side.

So, when doing your testing and close-up examination,
be sure to rotate the PSU through 180 degrees:
the upright position was the culprit, because the
fan bearing allowed the fan blades to drop down
just enough to touch the wire grill.


Solution: just bend that wire grill slightly away from the fan blades.


This may or may not be the problem you are having,
but it's a very quick and inexpensive fix, if this is the problem :) 


Hope this helps.

I'm not sure how it could be the fan since it starts as soon as it's plugged in (with it only powering the ASUS' motherboard light.)

Mine Corsair PSU does same thing. I've got new (same type) PSU as replacement, but this one makes even louder noise. And it's not fan's noise, it's sound of it's electric components (capacitor or coil).
