High speed Video card that will work on this Borad wont take more than 30 Watts, Hard Drive will take 5-8 watt in ideal stage  and optical drive while working will drain max 18watts of power. So you are good with the 250 Watts of power supply with this Motherboard and CPU. If you want to add few more drives and additional components, you can go for 350 watts power supply. But more than that will not benifit  for this configuration, rather will increase energy Bill.

For this configuration, 350 watts power supply is recomended, still there will be a lot of headroom for other components as well.

Minimum Power Supply for this configuration you need is 180Watts. You can use any ATX powersupply with 250 Watts onward.

Mobo has a PCIe 2.0 slot and can accept higher end video cards that draw much more than 30 watts. 300 to 350 watts is adequate with a quality power supply and a basic video card but more may be needed depending on video card. Ensure that PSU has 20 amps or more on the +12V rail(s).

I guess with Pentium D Processor 930 one will never use NVIDIA Quadro 5000  or ATI FirePro V8800.
