My old motherboard died recently, so I had to upgrade my mobo, CPU, and RAM. Also added a DVD burner. Anyway, after building (or re-building) my pc, I decided now's the time to address this longstanding noise that's been coming from the Corsair VX450 PSU. It's an electronic buzzing or chirping noise that is definitely coming from the PSU and it intensifies when I move the mouse or scroll a page with the mouse wheel. It doesn't happen when first booting and going into BIOS setup. It begins as soon as the Starting Windows logo appears. Whenever my CPU shows a load of about 50% or more, then the noise ceases. I tested this using Prime 95 and PCMark 7, as well as when playing Command & Conquer 3.
I RMA'd the unit, but the replacement is doing the exact same thing! Doing a lot of research and found just how common this problem is for Corsair and other manufacturers. I'm reluctant to do another RMA, so I'm hoping that there's something in the BIOS that I can adjust.
Here's what I've tried so far:
- Disconnected all drives, graphics card, case fan, front panel USB and audio cables.
- In BIOS setup, disabled C1E under CPU Configuration.
- In BIOS setup, disabled Anti-Surge Support under Power.
- Connected the power cable to another outlet in another room on a different power circuit.
I read a possible solution that someone found that involved fixing Vcore to 1.2V, but I don't know how to do that and I'm frankly very nervous since I've never messed around with voltages.
(I also didn't install every driver or utility on the motherboard CD, in case that is relevant.)
Could really use some advice from you kind folks. This buzzing is really getting on my nerves!
