GTX 670 sli with a 600w PSU?

[bkbarrin]

I have recently built a new gaming rig and would like to make one additional upgrade to it by sli'ing another GTX 670 with the one I already have, namely because its a cheaper way to match the power of the Titan, but adding the cost of a new PSU may not be worth my while. I just want to know if my current PSU can sport two 670's with the other components I'm currently running. Here is my build:

CPU- i5 4670k (Initially 3.4 gHz, overclocked to 4.0 gHz)
GPU- Gigabyte 2 Fan GTX 670 (2gb vram DDR5)
Motherboard- MSI Z87-G43
RAM- Two 4gb 1600 mhz
PSU- Corsair CX600

If you do recommend an upgraded PSU, I'd appreciate some suggstions, but in the mean time I am doing my research.

No , it cant support SLI of 670's.

Here's a SEASONIC that will do the job.

No suggested 750W or higher. The XFX SR-71 listed is excellent
