A 550w power supply would be plenty to run that system, but I would say 600-650 would be around optimal. If you want to Crossfire in the future, I would get at least a 750w power supply, with 850w being close to optimal. But the key to choosing a power supply is to make sure you get a good quality brand/model, not just look at the wattage it can supply (or says it can supply)

What setup do you have? Having more watts than needed won't hurt anything, to a point. A system topping out at 450w draw would be at near-perfect efficiency for a 1000w unit, so that would be fine. It takes some strong components to pull that much power though, unless you're in SLI/Crossfire.

BleedingEdgeTek is correct. To sum it up, NO, having more power then the PC needs (at maximum draw) will not hurt your PSU nor your system. The PSU will actually run cooler and probably last much longer if it is a bit overpowered.
