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 :)

    All points out to 750W being more than enough.
