Is 500w enough

[kenng]

Im hoping to upgrade my system in the not too distant future. Though, im concerned that a cx500 wont be enough power. I want to upgrade my processor to a Phenom ii x4, my GPU to a 7870 (already ordered and on the way) and maybe a little more ram. my only worry is the processor with the 7870. The processor alone takes 125w. So is the corsair cx500 enough?

Current specs:
CPU: athlon ii x3 450
GPU: asus 6670 gddr5
Ram: 4gb Gskill ripjaws
Mobo: Asrock 880gm-le
PSU: Corsair cx500

Easily

The CX500 will be more than enough for that build, even after the upgrades. You don't need to worry.
