I think you could do better for a decent power supply than the OCZ. While OCZ is not a bad power supply, it is not in the same class as the Corsair units. I recommend the Corsair 650 and if you are planning on moving (or even remotely think you might) up to a faster video card in the next year or so, go for the Corsair 750:
