The 500W Antec PSU I had 4 years ago had similar 12v rails (18a and 17a I think) and I was using a much weaker CPU at the time (athlon x2). I can't remember if it was the 7900GTX, 7950GX2 or the 8800GTX that did it (I had them all in a span of 8 months ), but my PSU started whistling and I had to RMA it. I'd never lost a good PSU before that, so I figured it was just overloaded.

Just to be safe, I bought my OCZ GameXStream700W (4 12v rails at 18a each) and used the replacement Antec 500W in another (weaker) system where its been running fine 2 1/2 years with no whistling.

Since then I've been a bit more careful about how much I load onto a PSU, especially if it isn't a good name brand.

If you want to get a new unit musman, there are a lot of options it just depends how much you have to spend. Corsair's PSUs are among the best you can buy, but you're looking at $100 for one that'd be good for your setup.

This OCZ StealthXStream 600W should be good for you though and its cheaper:

Hmm, I didn't take a close look at his PSU. The Rosewill I was using had quad 12V with ~18A each rails, and it was only 30W more power, so I just assumed his was as well. Taking a closer look, seeing that its only dual 12V with 19A each, that is fairly weaksauce for a 600W PSU.

Other factors will go into how well your PSU performs also, but perhaps it might be best to upgrade the PSU.
