Everytime my UPS kicks in and runs on battery my Enermax power supply makes a loud buzzing noise. At first i thought it was the UPS so i returned it and got another one but the noise is still there. Could it be a bad power supply?

Well it seems I need a UPS with true sine wave output instead of a simulated sine wave ouput because the Enermax PSU has active PFC. :roll: FFS I've had some problems with power supplies since I got my latest rig. 2 coolermasters and this enermax .. although the enermax is a great power supply .. I can't be buying a true sine UPS cuz they are expensive. So looks like I gotta try to sell my enermax and get a different model. GREAT.

I never even knew about this issue so I guess I've been lucky with PSU/UPS's. :?
