Default Electrical Buzzing Noise From PSU

Hi hopefully you guys will be able to help me out with my situation. Their are few threads that pretty similar to my situation but Im still unable to pin point the problem.

I have noticed an electrical buzzing noise coming from my PSU by only plugging in the power cord from the outlet and switching the power button on the PSU. I have tried numerous PSU and different outlet within the house (6 years old) with the same result an annoying but soft buzzing noise which Im pretty sure is coming from the transformer. Is this buzzing noise coming from my PSU normal or would a UPS with AVR solve the problem? I would appreciate any recommendations or personal experience that may resolve this problem. Thanks
