Ah, well, I heard "going up" Is better because overtime eventually the components will degrade, so having a little cushion would be better, I was thinking about that Corsair 850HX Especially since I am going to most likely be getting a 5970.. Soon
Hi SS. If your system specifications are accurate, I'd say that you need a 600-750W PSU. There are many good products which you can choose from, depending on what aspect of performance takes priority for you and how much you are willing to spend.
