PSU whine! Help needed.

post #1 of 4
Thread Starter 
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.

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.

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

TIA

Gtx570 is a 220w GPU and draws a bit more when OC and in bench. Based on what you have, your rig should not use more than 500w. That Antec new 650 can pull 54a on 12v. Unless this is faulty unit, it should be a problem.

If it is psu related, as i believe it is, then you should disable your oc immediately. It seems that when the gpu tries to fully power up, the psu becomes unable to spare another 75+75=150watt supply. A good 650w psu should be able to handle that card.
try running games one last time after disabling all oc parameters. Dont play games till you get a new power supply.

Thanks for the info guys. Good stuff from both of you. +reps.

I think it's a faulty PSU too tbh, will have to exchange it i think, just to be on the safe side. Try to resist the temptation to play games until the new unit arrives.

Cheers
