Every PSU whines?!

[tragd]

So I've gone through about 5 different PSUs, including M12D 850w and corsair ax750 (2 of them).

And literally every single PSU has given me whine after a little use.

Am I just being really picky? (The case is on my desk, and I am able to hear it)
Or is this not supposed to happen?

I can notice the whine go away when I up the load (P95) or do something, but sitting on desktop, every PSU so far has given me whine...

It is annoying, but if this is the case with every single PSU out there, I will give up.

maybe bad luck? hows the juice coming from the wall? did you try another ups/power bar?

Are you sure it's the PSU that's whining? And not the graphics card?

If by some chance its the PSU and not the VC thats giving you this whine, try getting a good quality Line Conditioner and see if that takes it away.
Maybe you have really dirty power comming from that wall outlet.

it's definitely the PSU, and not video card.
I will try to find a line conditioner/ups or something and do that.
thanks for suggestions.

What's the rest of your hardware?

I find that Gigabyte motherboards with the advanced C-states can cause whining problems. My AX750 squeals like MAD on a H55M-USB3. M12D-850 squeals gently with an X58-UD5.

Sometimes it can be really confusing where the whine is coming from (ive seen this issue before)

To be 100% sure (not that i doubt you) just get some small tubing or hose about 40cm long and put one end to your ear and move the other end over the GPU and the PSU to eliminate any doubt?

This will give you an accurate idea (it would suck to go through another PSU to find it was the GPU)

Anyway good luck

This is when Zero is missed......

Dirty power can cause the transformers to whine in the PSU. Definitely try a conditioner. Also, how far away are you from your distribution transformer and what kind of typical load do you have in your house?

True. You will get no argument from me on that.


As for this situation, I still believe a line conditioner would be the best way to narrow down the issue.
