(UPDATE)Ok so since someone suggested I get a different brand, which one should do the trick? Not forgetting it's got to have 4 x 6 pin video card connectors because I have 2 video cards.

Corsair HX1050W power supply looks like it might have what I need

I'm guessing this isn't normal? Should I take it back, or is this just something that happens? I've heard this whistle in a bunch of high voltage gear but never in anything as low voltage as a computer power supply.

Video for proof. The whistle is pretty high pitched so you might need a set of speakers/headphones capable of reproducing really high frequencies to hear it. Those $10 flea market speakers might not cut it.



MW3 runs fine, I can crank out videos from virtualdub with no issues, the only game I have that crashes is the sims 3 which produces a BSOD with some direct x error (I think). The fact that everything except the sims 3 is stable kind of makes me think it's not the PSU's fault but maybe the sims is tickling a part of the video card that nothing else uses and the PSU just gives up so it's one of my suspects.

That's the 2 video cards, they don't get any quieter. If your speakers are capable of really high frequencies the whistle is quite loud and obvious. I can hear it really well on my headphones.

playing around with a sound EQ it seems to me the whistle is somewhere up from 10khz - 20khz (eq only goes to 20).

^ that, or its fan, but more likely ^

have it replaced

your PSU should not be trying to communicate with the neighbour's dog

Take it back and get it replaced.

My Antec High Current Gamer PSU made an intermittent ticking/tapping noise when I first bought it. Took it back and Antec replaced it through the RMA.

If it an antec then rma it sell the rma'd unit to a noob and get something that isn't a steaming pile of shit

hit it harder :P

I'd recommend anything Silverstone Whoop.
You'll pay a little more, but they're well worth every cent!

Well I took it back tonight, hopefully it won't fuck me over and not make its noises. I'll get a decent one & tear the "new" one a new asshole & turn it into a lab power supply to power my battery chargers & stuff.
