I am sick of electricity failures ... so I've decided to buy a UPS
My PSU is: Enermax modu 82+ Active PFC 425W
I've heard that since it's Active PFC I can't use any UPS, only one with True sine wave (I don't have any knowledge in electricity)
Is it true that I can't use any UPS with this Enermax PSU ?
if so, which UPS can I buy and what parameters should I look for when searching for UPSs ?
The Cyberpower PFCLCD series use this sine wave technology compatible with active PFC PSUs. I have two (1500va and 1000va) and have tested them with two of my systems using the active PFC PSUs. They work without fail. They have decent software for managing shutdowns, the switchover threshold, and monitoring outages, surges, spikes, etc...
For your wattage, you could pickup the 1000va model:
