What power supply do i need?

[GTA1989]

Im upgrading my system to a Athlon64 3000+, Asus A8N-SLi, 1 Gb DDR 400, Evga PCI Express 6600GT, and eventually get another videocard to run in SLi mode. My question is, what power supply do i need?

I was intending to get this case and psu.

Im a little confused as to ATX 2.03, whereas the power supplies are ATX 2.01.. :S

i don't think that case is worth that much. It's reall plain, if you want a cooler looking case for that price go here: http://www.xoxide.com/pccases.html

but if ur gonna get one from here, make sure to get one that your mobo fits in, because they have a lot of different size cases.

For that much power... I suggest a 400W psu, maybe 500W if you want to elongate your psu's life and keep it for a while. RUnning at 90% the power of your psu is not good for it. Something like this:

will do the best for you...

what do u mean running it at 90% of it's power isn't good for it. should u use 100% of the power, or get more power than u need.

No No No.... bad. You have the wrong idea. Running the psu at 90% of its limit is bad. Very bad. It shorten's its life considerably. Use no more than 80% usually. If you overclock once in a while and push the limits for short period, it won't be bad, but running the psu at 90% of its limi all the time will have you looking for another one very shortly. The more power you have, the longer you can keep your components. Hope this helps...

case

and as for power supply choose one of the ones they got nice ones. i dont think that case is worth it if u really want a case get that one with like one of tehre 500watt power supplys. u can buy it with a ps just choose one at the bottom.

Yeah, that case works nicely. Plus has a nice little addition on top...

I personally like the Aspire cases. Most of them have a nice clean look to them.

I know it only has a 350watt power supply, but you can always change that out and buy a better one. Keep the 350watt stock power supply as a spare or tester.

or here's another nice one that has an adequate power supply. This is what I would get:
