Need help with choosing PSU - gtx 760, FX-8320

[skygazer842]

Hi guys
I am building a new rig, video card - gtx 760, CPU - FX-8320. I plan to overclock video card and CPU, my current PSU is Chieftec CTG-550C. Is it enough for my needs?

If not, could you recommend me an appropriate PSU?

550 is plenty, although chieftec isn't a brand I'm familiar with.
