GTX 670 in SLI power consumption

[Spartacus394]

Alright, I know that there are articles about this stuff, but everything I saw wasn't exactly what I needed.

I'm looking into getting 2 MSI GeForce GTX 670 PEs and puting them in SLI. My concern is weather or not I'll have a big enough power supply. I will mostly be gaming with a side of video creating/editing.

Specs:
i5-3570k (I'm thinking about getting an i7-3770k for better video editing)
ASRock Z77 Extreme6
8gb Ram
OCZ ModXStream Pro 600w

What do you guys think? I'm still new to PC building and I'm not sure how everything works. The GTX 670 says it requires a minimum of 500w PSU so I know I'd be fine with just one. I already have the PSU so if it's too much for my PSU I'll just get one for now.

The two card in load might reach ~340w, it still leaves a margin with cpu, that psu can pull ~600w, it will be almost at full load when gaming, that psu proved to be efficient at 550-600ish load : http://www.hardwaresecrets.com/article/OCZ-ModXStream-Pro-600-W-Power-Supply-Review/936/7

So I should be ok then?

It should, but you'll be stressing the psu, in gaming.
But it should be fine.

Alright. I'm just gonna stick to getting one 670 for now and I'll get another one with a bigger PSU later.

Thanks!
