Ok, I tried warranty and they said it was probably my fault or the fault of the electricity company. I didn't want to use lots of time for this problem, so I just bought a new one. The OCZ ModXstream PRO 600 Watt, because it's modular and nice and quiet.
Nice choice! = i own two of those:)
You should add a decent surge protector = spend at least $20.
Anything less is a glorified extension cord.
