so what actually happen with the luminous ups?
I have APC 600va and it works with my CX430v2 but with humming sound from PSU as well as speakers(Due to square wave)
Did you return the Luminous as you have ordered it online? tell some reason and get refund ASAP.
it restarts straightway. not going to return since its good quality build... think its just problem with my vs550 psu. going to change that to antec 450p or corsair CX series
i also have apc 600va which doesn't face such problems (although it did get restart about 2/3 times in last month)
