Just go off what your graphic card needs. A high end card will generally require a 500-550W psu unless it's a dual gpu card then you are 750W+. The rest of the system doesn't pull enough to have a real affect.

Use this link as a guide. It does not hurt to overprovision a bit.
The psu will use only the wattage that is demanded of it, and will operate most efficiently in the middle third of it's range.

Thanks crewton and geofelt for you reply .
geofelt :: That link was really helpful .

Conclusion : Your Power-supply depends on Graphics card otherwise without graphics card a 500WATT 80+ efficiency PSU will Do ,
again it depend on graphics card , you need more power supply if you are using crossfire / sli features .
both answers were helpful , the link is very use-full .
