I'm running a system I built using a system guide 2 years ago. The guide suggested a case with a built-in Antec 380 Earthwatts PSU. The PSU has served me fine despite a lot of friends telling me it wasn't enough juice to run the system(AMD X3 435 and Radeon 5770).

I'm looking to upgrade the vid card possibly to a 6850 and maybe upgrade the CPU to a Phenom II X4 or X6. I'm wondering if this PSU will still get the job done? If not, and this will sound dumb, but how do I know the size of the CPU to buy?

I want to use the same case and have always bought cases with the PSU built-in. Here is a link to the case: http://www.newegg.com/Product/Product.aspx?Item=N82E16811129059

Thanks for any help and advice!
