I really think you could get by easily with a quality 750watt PSU, Corsair of course comes to mind, You might give this a look.

You dont need alot of power for that, a corsair hx620 will be fine for that system.

Technically, even a Zeus ST56ZF will run that without problems, but I'd suggest you go with an Indy regulated unit like the Corsair TX750 or BFG-800ES (if you are more comfortable using a larger wattage unit) as mentioned by Scott and Cabose. What is your budget, BTW?

620 would be fine. Even a 520 would power that.
