While the above figures give you a ball-park figure for what wattage your PSU should be able to handle, it then becomes a matter of ensuring that you get a PSU which *will* be able to 'deliver' because many PSUs (including expensive ones) claim one thing but simply do not 'deliver' when it comes to the crunch.
Just to back up Basil's comments... I had loads of odd and unsolvable problems with peripheral devices (like printers), and randomly failing hard drives (that worked fine when put into a second test machine). Very frustrating problems that I knew should not be a problem, or should be easily solved. I ended up replacing the PSU with a BeQuiet 600W (http://www.be-quiet.net), and that cleared it all up. The computer has been rock solid stable ever since. Now the only issues I have are all the ones I create by tinkering.
