Power Supply HX620W and UPS


Recommended Posts

I own a Corsair HX620W, that is with active PFC. Could there be any problems in using a cheap UPS with approximate sinewave?


Should not be any problems, however some users have noticed a slight buzzing noise coming from the PSU when using a cheaper UPS. The buzzing would not indicate any problems, and usually will only occur when running on battery power.
