I'm planning on upgrading my current setup by buying a Sapphire 7970 Vapor-x 3gb, an aftermarket heatsink - Cooler Master 212EVO and an extra 500gb 7200rpm hard drive.
So, in the end the build will look like this:
Motherboard: Asus p8z68-v pro/gen 3
CPU: Intel i5 2500k
RAM: 2x Corsair XMS3 4gb
GPU: Sapphire HD7970 vapor-x 3gb
HDD: SAMSUNG Spinpoint F3 1TB and Western Digital CAVIAR Blue 500GB
Heatsink: Cooler Master 212EVO
Total of 4 case fans.
PSU: Corsair CX600v2
I'm not sure that my Power supply will be able to handle the system, it has 40A on a +12V rail, which I think results in 480W. Am I ok to stick with it? I do plan on overclocking, eventually. But it can wait, since, I think this build can run pretty much everything on decent settings.
You will will be close to above power consumption, (maybe slightly less) They used a higher end CPU, But only used a single SSD and No DVD drive and 16 gigs Ram verse your 8 Gigs.
Bottom Line, Yes CX600 is fine as long as you do not xfire in the future.
Personally I consider the Corsair (love them) CX line-up as a Mid grade PSU, Thier entry level PSU, and prefer the TX and HX line-up - AX just flat out to expensive. Believe the CS line is a cut above the CX
