PSU & Case help.

[Rburma]

I'm building a new P.C (790GX, Phenom II 955, HD 4890, 1tb SATA 3gb/s HDD, 8gb DDR3 1333)

How hefty of a power supply do I need to buy, and would all of this fit into a mid ATX case?

This should be more than enough

And it should fit into a mid ATX case, but which one are you using?

Here is another option that is a little cheaper:

Do you have plans to overclock your system? And what case are you planning on using?
