In general, provided that you won't OC neither your CPU or GPU 600W PSU is more than enough for this card.
However CX series from Corsair is no where as good and is known to be a "dodgy" series of PSU-s.
If you can afford it, something from AX series from Crosair (re branded Seasonic with 7 year warranty and cheaper). This should cover all your needs.
If not, then HX or even refreshed VX v.2 series will do just fine.
Or just get a Seasonic PSU and be done with it.
