Hi everybody, this issue is getting me crazy. Here's my story:
I bought HX1000i, connected everything, turned on and was really happy. Then during the night in the silent room (because I have almost noiseless system - 3x Noctua fans on 400 rpm in idle are inaudible) I realized something is making a very low electrical constant buzzing sound. So I turned OFF the PC and the buzz was still there! I put my ears to the case and the noise was louder. Then I put my ears on the metal case of PSU and here we go, TRANSFORMERS buzzing. Usually this is not a problem for 99% of people, but if you have a super silent PC you want to have super silent PSU. OK, I thought it was a bad luck so I've ordered RM750W instead and guess what, exactly the same buzz from transformers.
So, I told myself I will abandon corsair and bought Seasonic X 750W.... And ? The same buzzing as corsairs... Then I've read somewhere that transformers in corsairs are provided by Seasonic :) So I don't know what brand produce PSU with non buzzing transformers....
Now I'm asking myself, is there a PSU which is not making any noise in standby mode ??? With PC turned off ? Did I have just a bad luck with those 3 PSU ? I have an older Antec 520W and there is no buzzing whatsoever so this needs to be some manufacture flaw. I would love Corsair's PSU if even there is no such issue :(
