No prob. Like Pingy and ttcboy said, you really don't need all that power, as your system draws around 400W (Around 440 w monitor) I'm building a 3470 system that draws around 350W, and it draws about 360W with no overclocking, and I have a 550W PSU for it. It would only make sense that with the more powerful parts you are using, that you have upwards of a 600W PSU.
