PSU strange beep after shut down

post #1 of 12
Thread Starter 
So I just put together an HTPC, but when I shut it down it beeps. It's a continuous beep that sounds like it's coming from the PSU. I ran the idea by in another thread on a different topic and I got bad capacitors.

I hit up Corsair's website (it's a CX430) to email them to ask about their RMA policy since the place I ordered from only refunds and it may cost a restocking fee and I hit up the FAQ's and found this:

Q: Why does my computer emit a strange beep when it shuts down?

A: The loud beep heard during shut down is a warning from the video card that it is unpowered. Typically on shut down, the video card will have a small delay to account for the loss of power from multiple sources, such as the power it gets through the PCI-Express slot and the power it gets through the power supply connector(s). It is not uncommon for one source to shut down a fraction of a second before the other due to hardware variance, and it will not harm your video card, power supply, or motherboard. In this case, that delay is insufficient to accommodate the gap between the loss of power from those two separate sources. Should the motherboard stay powered a fraction of a second longer than the cable(s) to the PSU, the video card alarm delay is triggered and there will be a short squawk from the video card’s onboard alarm speaker. This can happen with any power supply and any video card, and replacing the power supply may not fix the issue due to fact that power off timing changes slightly (even between seemingly identical units) due to that hardware variation. In some cases, it may be possible to fix this issue with a new BIOS for your video card that increases the delay slightly. For more information on obtaining a newer BIOS, contact your video card’s manufacturer.

So that leads me to believe I'm not getting enough power. Here are my specs:

Asus P5G41T-M/CSM
Intel E6500 (OC'd from 2.93GHz to 3.00GHz to get the FSB to 333MHz so I can get my RAM to go to 1333MHz)
G.Skill Ripjaws 1333MHz 4GB (2x2GB)
Gigabyte GT 430
Two old WD 500GB's, about 3 years old
One 140mm Scythe Kazemaru 2 fan (that's not plugged in right now)
SilenX 80mm CPU cooler
DVD drive
A couple card readers up front, one's two USB ports and one's an SD card and a USB

Do I need to send the PSU back and get a new one or what? I've got the latest BIOS for the mobo. Then again this doesn't say if the beep is prolonged or not. I did a quick computation on a generic power supply calculator site for this build and got 330W.

That PSU should be enough for that system IMO, but you could try disconnecting some unneeded drives/ dvd rives, fans, usb devices ect, and see if it makes any difference.

That in no way follows from Corsair's response. Read through their reply again. It's nothing to do with too little power, it's simply a shutdown timing issue (assuming they are correct). Even if they're wrong, having too little power would not cause anything like the symptoms described.

I thought the PSU should have been enough as well.

I've run it without the second HD before, could try everything else... but I dunno. Any other ideas?

EDIT:
@Phaedra: I thought the same thing... but it seemed too coincidental to ignore -- me going to ask them and just happening on this. What would you say would cause my symptoms? Some more info is that it only beeps AFTER the computer's been running and stops when I switch off the PSU. If I turn it on it's fine, but after it's run and shut down it beeps. Not really beeps though, bad word. It's like a whine.

You could do what Corsair says and try flashing a new BIOS. Since, you know, they do seem to know what they're talking about.

I'm on the most recent BIOS.

EDIT: Didn't see it was card BIOS, not mobo BIOS. I'll look into that.

Mobo has built-in video, so I removed the GT 430 and booted. Shut down, same beeping/whining. Removed the PSU from the case just to attempt to isolate where the noise was coming from and it's definitely from the PSU.

Guess I'm left with sending 'er back/RMA'ing.

The PSU doesn't have a speaker in it...

Well aware that PSU's don't have speakers in them. I'm only chose the word beep because that's what it said on Corsair's sight. Then, if you'll read earlier, I changed it to whine. I was told it could be bad/crappy capacitors. The point is my PSU is emitting a noise that it shouldn't be.
