Just use this website: http://www.extreme.outervision.com/psucalculatorlite.js... FYI, the figure this site generates is only a ball park, and so should be taken with a pinch of salt. As a general rule, I always add another 100-150 watts on top of what the site suggests, for both inacuracies and upgrades. Hope this helps!
