Not much, 400W is fine. What's your budget?

For power supply needs in zones I'm not too familiar with, I usually use a PSU calculator.

a decent 300w PSU is all that's needed with a bit of room to spare. Peak power consumption on a rig like that would be approx 200 watts, due in large part to that Pentium D.
