Is my PSU sufficient enough for my planned upgrade?

[Guest]

Hello

I'm planning my next GPU upgrade and was wondering if my PSU is going to make the cut. I have a Corsair Builder Series CXM 600W Modular 80 PLUS Bronze Certified PSU and wanted to use it with a GTX 970 or potentially a GTX 780.

My current rig (Minus GPU) is below:

Motherboard: Asus P8Z77-V LX
OS: Windows 7 Ultimate 64
RAM: 8GB
Memory: WD 1TB 3.5 inch Internal Hard Drive
CPU: Intel i5 3570 @ 3.40GHz
PSU: Corsair Builder Series CXM 600W Modular 80 PLUS Bronze Certified

Thank you

For GTX 970 is fine . Even for GTX 780 is sufficient
