How to figure out how many watts is enough for your power supply?

I just ordered parts to put together a good fast system. I ordered a 750w power supply and am wondering if it is enough.

If you want to know exactly what I'll be running off of it, it is listed here:

But I'd like to know the forumla for figuring it out for other systems I build too.

Drop the Rosewill PSU, from the look of things a good quality 650W will be more than enough. Look for: Antec, BFG, Corsair, PC P&C, OCZ, or Silverstone (unless in a 220v area).

Why do people ask after they've already ordered? I don't understand that logic.

That particular Rosewill is a new one; 80+ bronze certified, with Active PFC. While the older Rosewills were lessons in overrated suckage, that new model should be decent. At the very least, it was run at 100% during the certification process, and didn't croak.
