Um, mine was a normal, working PSU (5 years, 2 Mobos). Generic though. At one moment though my Mobo mysteriously stops powering up (at all - fans etc.) even with another psu. Now plugged in another mobo, power on does half a revolution (fan) and no more. Hope it didn't fry the second one. CPU seems also fried on the first one. Is that possible (Asus A7V KT133 - the old one with the seperate ATA 100)
