Hello ya'll!

First i'd like to say sorry if I put this in the wrong category, feel free to move it to the correct one.

When I first got help to build this system I have i didn't plan to run SLI, but now as my friend bought a 780 card, I got his Nvidia GTX 670. So what I'm wondering is, would I be able to run SLI on my current XFX ProSeries Core Edition 550W PSU?

More system speccs:
Gigabyte GA-Z77X-D3H, Socket-1155
Intel® Core i5-3570K Processor
Cooler Master Hyper 212 Evo CPU Kjøler
2x ASUS GeForce GTX 670 2GB PhysX CUDA
Crucial m4 SSD 2.5" 128GB
Seagate Barracuda® 2TB
Samsung DVD±RW Writer, SH-222BB
XFX ProSeries Core Edition 550W PSU
Corsair Vengeance DDR3 1600MHz 8GB CL9
Fractal Design Define R3 Black Pearl
Noctua NF-P14 FLX 140mm Vifte

the GTX670 has a max TPD of 170W, so you will be really tigh on that SLI, reducing PSU life expectancy, for that SLI I recommend a 750W from that same series for instance(XFX 750W pro series)

any from 750W and up
