How Much Power Do I Need?

[8du8]

Planning to build a HTPC with some old parts but I find that I tend to go overkill sometimes with PSU's and thought I'd ask here for some advice.

What would I need for:

Core 2 Duo E6600
Geforce 8800 GT
4gb of ram
1 500gb 7200rpm hard drive
1 optical drive

I'm not sure how much gaming I will do with it since I game on my desktop, is it worth it to replace the 8800 GT with a less power consuming card? Thoughts?

It will more likely than not pull around 320 watts, Buy a corsair http://www.newegg.com/Product/Product.aspx?Item=N82E16817139026

CX430 V2, especially when it goes on sale for ~$20.

The Antec Earthwatts psu isn't to bad and can usually be picked up on sale.

Thanks for the replies, think I'll just go with the CX430.
