I am wondering why my psu is making whining noise? I have an older ocz 1000w (in sig) and i thought there was a lot of life left.. all my specs are in my signature below. I have used the psu tester to see how many watts my system will use and its only 621 watts.
Are you hearing a whining noise from the fan or something else? In some cases you may hear a high pitch whisting noise because of high frequency vibrations. Old tube tv's had this problem from time to time from the high voltage flyback transformer. It usually doesn't mean you will have a failure but it is annoying.
