Hey guys I have a Corsair TX 750W V2 80 plus bronze certified unit and wondering if I would be able to run gtx 670s in sli? Here is my power supply link as a reference:

or you will need a more powerfull PSU, 700 will be a bit... on "red zone".

Will definately work. I used one of those with a GTX470 SLI system a while back...with zero problems. GTX470s are way more power hungry than GTX670s. I also had 2x DVD writers, an O/C 970, 5x Harddrives, a camera, a TrackIR, a magicJack, headphones and a whole host of other things being powered.

with 670 x2 in SLI and 2500k (as it is his CPU) it should work as 750w is recomended but i guess he will overclock those babies (unless he would have used a non "k" i5 CPU and NVidia overclock very nicely lol).

when overclocked they will consume more, despite less of the previous generation.
exemple: with corsair 850w i was ok with single 590GTX even in full stress but when start overclocked i started shuttering and having artefact on screen... after test i discover that the issue is not from the GPU card but from the PSU that is not powerfull enough (i was at nearly 900w)... i still have this GPU (with another one for SLI) and i run without problem nearly 27/7 overclocked without any issue after having changed my PSU.
BTW: my old psu is on another smaller computer and is still 100% working as corsair are rock solid PSU

So basically I have made my mind up and think I am going to go for getting 2 EVGA GTX 670 FTW edition video cards to SLi. Since it will most definitely work without a problem, I will pick up one for now and in a month or two get another one. 2 of these babies will beat the crap out of a gtx 680 and even 1 EVGA GTX 670 FTW is better then a stock 680!

Also I won't need to overclock them at all anyway with the FTW Edition cards. Will I be able to OC them a bit higher? Atleast the one card I get for now I will OC a bit so it beats most of the GTX 680's by itself! So my question is when I get another of the GTX 670 FTW Editions, will I be able to OC or I should really just keep at stock clocks since they are factory OCed anyway right?

Only question is get the FTW Edition or the ASUS DCII Top, yes, I saw the negative reviews, but most of the people are getting good reviews plus the amazing review on TechPowerUp a 10/10 rating. for the first time ever for the Top Edition! Is it a dual slot card?

670s really don't need much power at all so it shouldn't be a problem. Even with full overclock I'd get along fine with a 400W psu so 750W (a good one of course!) for two cards wouldn't be a problem at all.
