Solved 200W PSU enough?

From what everyone is saying you should do well with a 250 watt, please look for a bronze or silver rating if at all possible.

When you run PSU calculator like Britton30 did for you it has a "capacitor aging" factor. This has a significant impact on the recommended PSU ratings. I would guess cheap PSU = cheap electrolytic capacitors = crank the aging factor up.
