The power supply calculator above will give you a good, generous estimate of the wattage of PSU your system will need. It does err on the side of being slightly high, because it assumes all components are under full load at once, which in practice they practically never will be. However since the load on the PSU depends more on which rails (the "power lines" of the PSU: normally there will be a 3V, a 5V and one or more 12V rails) are being put under strain.
For all intents and purposes though, unless you're building a very lopsided system (like with 12 hard disks or whatever) it will give you a very good idea of what you need.
