Help!

My PSU is the Antec 650w TruePowerNew PSU. Performance was great until i plugged in my new Phantom 570. During loading screens for games (amd, intel + nvidia logos etc), i get this horrible high-pitched squeeling sound (different pitch/whine depending on the loading screen, load up a game and it's sound like a bloody orchestra lol). Same thing actually happened on my old Gigabyte 460 but to a much lesser extent, i just thought it was graphics card capacitor whine due to overclocking. At first i thought my new graphics card might be the problem, but i have definatly narrowed it down to my PSU as being the cause. The more i overclock my new 570 the more the whine becomes noticable until the point where it's just constantly squeeling, loading screens or not. Kind of a bummer seeing as i've put so much effort into builing a quiet rig.

Am willing to replace my PSU (somewhat reluctanly) but i was wandering if there was anything i could do to undo the effect???

Any advice on what i should do would be greatly appreciated. Thanks

Seems like it is (over)maxing out the PSU hence the noise yet that is pretty weird as it should be more then enough

And Antec is a good brand never had a single problem with these PSU's ...

Do you have a multimeter by any change ?

Sorry, got no multimeter.

And it's a semi-modular PSU btw, currently running my 570 off the single non-modular rail, but i don't think that's the problem. I've tried swapping to one of my modular rails and even tried splitting the power between them, but no configuation i try (i've tried them all) seems to work without making this high-pitched noise.

I've also been getting an occasional stutter which i can't seem to fix. Every now and then i'll be gaming and i start to get a lot of jerking, as if the card is starting and stopping rapidly, i'll exit the game and the same thing will happen in windows until i restart.

It's feels like a power draw problem, but as you say, my PSU should be enough to run what i'm running. I'm at a loss really.

Before you plugged in the 570 did you notice any power draws then ?

could be the PSU is ending its life

Same thing used to happen to my 460 when overclocked, i just thought it was the card. And it wasn't nearly as bad.

Plus i bought the PSU off Ebuyer quite recently, like 2-3 months ago. Guess i'll have to send them an e-mail and try to get it RMA'D i guess.
