Should i upgrade my Power Supply?

Im thinking about finally getting my graphics card a EVGA GTX 660. I was wondering if i would need to upgrade my power supply(Corsair builder series 600w). 

 

Motherboard: Asrock z77 extreme 4-m

Ram: Ripjawz X 2x4 1866

i5 2500k

in a Phantom 410 

What power supply are you currently using?

UPDATE: I misread the post. 600w is plenty for a 660, and OC on both CPU and GPU.

No, that PSU is fine, unless you intend to OC you should have no problems.

Alright thanks for the help guys.

Even with an OC, its fine.
