Quality PSU w/Case

[Wonderwill]

This case looks like it has a quality PSU included:

Antec LifeStyle SONATA II Piano Black Steel ATX Mid Tower

Will it support a C2D E6400 Computer with 2 gigs 533, 1 HD, Geforce 7600GT,
and Foxconn Mobo?

should work fine.

It will be more than enough to power that system. It's got a 450W Smart Power PSU. It's not a True Power, but it will do. Although, if you go by the newegg reviews (I don't, BTW), there have been a lot of those power supplies that die in 6-8 months. Oh well, you get what you pay for. I'm actually thinking of building a similar system to yours, but with a Gigabyte P965 S3 mobo.
Also, if you ever want to know how much power you need for your system, follow this link to figure it out PSU Calculator

Hope that helps!
