Well, I think my PSU is dead.... This is the 2nd TIME!, ive gotten a Forton/Sparkle PSU and was DOA. My brothers machine had a 530W forton, dead. My new cousins computer i got a 460 W Sparkle EPS, i think its a dud. I took the PSU home with me plugged it into the motherboard, just the 24 pin an 4 pin, i had adapters. The motherboard light wouldnt light up at all. So i tried shorting the green pin, with a black pin, and pplugged it in. nothing. This PSU has No On/off switch. I thought it was the mobo shorting out, but i installed those cardboard washers, and that didnt work either. I must have bad luck for getting dud PSUs, ill just go to PCclub and get an Enermax supply,and RMA this one.
