GTX 770 SLI Build issues

[Lhyde123]

So I'm building my first pc and a few of my friends are going to help me, together they have built many pc's. My problem however is I was originally going with the 780ti and have decided to switch to two GTX 770 SLI instead. I've been reading on the forum about problems people run into from SLI and running 2 GPU's. Any one else have any problems? I'm going to be treading into some new water now because my friends have never set up SLI before and wondering if any one has any tips from as far as performance goes and set up goes... Also before I decided to run two 770's I only bought a 750w PSU should this be enough or will I need to bump it up 50-100w?? Also I will continue reading the forums and threads (not trying to take the easy way out by posting this!) I just want a little insight and maybe some tips that other people have found over the years that maybe isn't posted yet. Thanks again!!!!

Looks good, 750 is the lowest I'd go with your rig, would prefer a 800 for a little extra breathing room. As far as the mobo and the rest, no problem, I'm running a paior of 780s in SLI on my Hero (in sig)....if you run into any problems give a shout

I would have stuck with a 780 Ti, but hey, dual 770s will be awesome lol For the most part, SLI isn't a hassle, it's AMD's Crossfire that is a hassle.

As you'll see below, a system running dual 770s with an overclocked i7 extreme pulls 550w at full load. 750w is on the weaker side, but I wouldn't worry about it.

Thanks guys. I made a few changes though.....
I upgraded to an 850w PSU, Ditched the two 770's and bought a 780ti, Ditched the G.Skills and got 4x4G 1866 Corsair dominator platinum. If I would have known I was going to make these changes I would have upgraded from the hero to the formula when I first bought them.. Should the hero be fine or do you guys think I am going to need to go ahead and get the formula or even extreme??

Well, if going 16GB then would suggest going 2x8GB rather than 4x4GB, less stress on the MC (memory controller) with 2 sticks rather than 4, and a hair faster
