Bought the 600VA/360W with 4 backup and 4 surge plugs. Hooked up to the 4 backup power outlets is a 27″ monitor, a tower PC, 5-port switch, and phone. The UPS is hooked up via the supplied USB cable to my PC and I let Windows manage it via the native Windows Power Manager, in the same way it would a laptop as it “sees” a battery.
