GTX 670 SLI Power Consumption

Hey everyone, I have a question about SLI-ing a GTX 670.
But first, the specs:
- Intel Core i7-3770 3.40GHz
- Gigabyte GTX 670 Factory OC WindForce 3X
- 8GB RAM
- Asus P8Z68-V PRO/GEN3 MOBO
- XFX PRO 750W Power Supply

I was thinking of buying myself another GTX 670 for Christmas so I could SLI the two but I was wondering whether I had a large enough Power supply to run the two along with the rest of my parts.

My Motherboard and power supply state they are SLI ready on their boxes, but I just wanted to make sure beforehand.

Any other tips on SLI-ing and/or recommendations for a different card to SLI would be much appreciated as well. I'll also provide any more information on my PC if you desire.

Thanks guys :) 

Best solution

nVidia itself recommend 500W for a single 670.

For testing conducted for SLI 670, the resulting system consumption for SLI is 433W of which 293W are attributed to the gpu cards.

If you use this psu calculator considering your components, the result is 664W (overclocked processor & used 680x2 to simulate gpu OC:

All points out to 750W being more than enough.
