Power Supply Screaming Bloody Murder

post #1 of 13
Thread Starter 
I'm not sure what section to post this in, but it seems to be effecting the power supply the most so here it goes. A couple weeks ago, I started folding and my power supply started making a screeching sound, and it went away a couple days later. Just a few days ago a couple buddies came over and i loaded up Codename Eagle (old game, but hilariously fun) to play over the LAN, and same deal, but even louder. The weird thing is, newer games like Unreal 3 and BF2142 run just fine with noise to be heard. Crysis will make the sound only in the menu. I'm really stumped. My 8800GT also made the sound a few days after I installed it (it would only make the sound running the cube in ATITool), but it seems to have disappeared as well. I don't think my power supply is being overworked, as I only have one optical drive, one hard drive, 2gb of ram (@1.8v) and my 8800GT. I didn't have the problem with my 7600GT or 7950GT, so i'm leaning toward the power supply, but i have 29 amps on 2 rails which is more than sufficient, right? I'm really stumped here.

29A across two 12V rails is pushing it, esp. when overclocking. It should (barely) be enough at stock, but the PSU will run out of breath when you overclock. Not sure what the 'screeching' sound is (electronics? A fan going nuts? some kind of build-in alarm?)

In short, I'd highly recommend a new PSU, with a bit more amps on the 12V rail(s). This Corsair is nice for just $99: http://www.newegg.com/Product/Produc...82E16817139004

It sounds like capacitors squealing, which it very well may be.

If I was going to spend that much, I'd want to get some more wattage. Anything you can recommend closer to the 650-700 watt range?

I'm really happy with my OCZ 700w. Great PSU for a reasonable price IMO. Hope this helps

I got mine for $88 from ncix a while ago (after rebate) but it doesn't look like that deal is still on.

For $100, I'd rather get that (proven high quality) Corsair than something that's 650W - 750W, but not as high quality. The Corsair delivers 41A on a single 12V rail, and there are plenty PSUs with higher Wattage that deliver the same or even less. Wattage isn't everything.

The most viable alternative is this 610W PC Power & Cooling unit (which isn't much more, given the free shipping):

Actually, the noise could be your GPU. They're known to make a high pitched squealing noise when they cannot draw enough power (which is somewhat determined by how high your FPS are, and might explain why an old game which is presumably much less stressful is causing the noise). A more powerful PSU would still be the fix regardless, though.
