recently I setup a new computer with a 480w truepower psu...everything was fine..tried to use it a week later and poof..nothing..hit power button ..fan spins and stops...
so I was annoyed...prior to swapping out psu and testing I tried a new power cord from UPS to PSU..and guess what everything was fine.....
so with NeoPower make sure you are using a working power cord...I should note the power cord I used was less than 1yr old(from 480w truepower which was a nrma on 480w that blew up)
