PSU making faint static/squeaking nose (link of sound attached)

Hello all,

I have another problem that just appeared recently. I just re-installed Windows on my new SSD and have been loving it lately...except my PSU seems to be making this noise that is very nerve wrecking after a while. It's a Corsair HX750 and I haven't had one problem with it before, but this has just recently happened.

Weird thing is that this noise happens the most when I'm browsing the internet. When I'm using Chrome the noise persists, however, usually when I'm gaming the noise cuts out.

I have isolated the problem to the PSU, so I know it's no other component. I also unscrewed it and re-screwed it, tried a new power plug but not of that worked. I hope I don't have to get a new PSU because this one has served me well.
I have attached a link to a video I took that shows the sound so maybe you guys can help me out.

I am running the following off it:
FX-8120 (3.8 Ghz, unparked my cores)
AMD 7950
Samsung 840 Evo 120GB SSD
8GB 1600 RAM
1TB Seagate HDD
2x 250GB Seagate HDD
4 Case Fans and 1 H50 Corsair Cooler

Thank you in advance

  1. im hearing a high pitch squeal sounds like coil whine.
  2. What do you think I should do?

    theres not a lot you can do mate. you can RMA it but you will likely get another psu with the same issue.
    or you can open it and get the hotglue out, inject it under the caps and coils to dampen the vibration that causes the squeal. but this can have a negative effect on heat dissipation if you use to much or put it in the wrong place.
  4. Thanks for the help. I think I'll just put up with it because it only really does with when I'm using Google Chrome. It doesn't make sense to me as it doesn't do it under light load (when CPU is at idle) or heavy load (when gaming). It really only does it when using some other small applications like Chrome and Firefox. I'll try and see if I can fix it at all by myself. But I don't think I'll be RMA'ing it cause it's working just fine.
  5. probably only happens at certain frequencies of voltages. any electronics engineer would be able to fix it for a small fee if your unwilling to return or fix it yourself. just a thought.
