PSU:Cool master silent pro 1200w
CUP: I 7 3930k 3.20ghz
MOB: ASUS rampage 4 extrm
GPU: gtx 780 ti directcu II

So I install one gpu and everything works now I install the second gpu and sli it I put it next to my other gpu and now my computer wont power up. Board and gpu both has power. I remove the second gpu and put it on the third slot and still no luck. I remove the second gpu and now my computer turns back on again. What could it be.

I already switch all the cards one by one and I already put each card at a time in each slot. Everything work with single gpu in. But as soon as I SLI it my computer wont turn on.

Try putting the second card in the first slot.Then try the second card in 2nd slot to see if you might have a bad slot
