Quick question on a PSU

[regulus]

Got a 980GTX coming next week. Never actually occurred to me to check whether my current PSU got enough kick to power this thing. Spec is;

8320 at stock
8gb RAM
600 OCZ PSU

Currently have an 7950 I clock now and again and never had any issues.

Should the PSU be alright?

Just copied it from my OCUK order from 2010;

OCZ ModXStream Pro 600w Silent SLI Certified Modular Power Supply

crazy to think I bought this just over 5 years ago (£49) and it's still dead silent and running as strong as day 1. Been through about 5 graphics cards and 3 CPUs, which is a slow month for some posters here I suppose.

Should be good enough?
