If http://extreme.outervision.com/PSUEngine is anything to go by, you need about 340W @ 90% full load. I usually double it up, round up to the nearest 50W, then do a +/- 50W spread. In other words, a 650W-750W should be good if you don't want to spend that much. However since you never usually have 90% full load a lot of the time, you can drop this down to about 600W and still be good.

Make sure the power supply is at least 80PLUS (Bronze or better preferably) and try to get a single 12V rail. There's nothing wrong with multiple rails, but since video cards require a lot of amps, you have to be certain which rail you're plugging into, otherwise you'll blow it out.

how do you know which rail to plug it into? Currently i have a 400w power supple hooked up and it smells of burning metal while i play world of warcraft at merely Fair quality. It is loud and gets very hot. a lot of the time it will just crash my entire computer while i am playing. i let it cool and it turns back on as normal. i have ordered the power supple mentioned above already so i really hope it will be enough and fix my problems. i would love to run this video card at top speed but im afraid to because my computer keeps dying. is your opinion that all of these symptoms will subside after installing this new PSU or is there another underlying cause?

Again what do you mean by specific railing?

Well the rail thing is only a problem if you use modular power supplies, and they should tell you. Otherwise it's probably a good idea to plug the PCI-Express power plugs in every other port. If you have a non-modular supply, then the manufacturer (usually) does the separation for you.
