PCIE connections

post #1 of 2
Thread Starter 
Hi. I have a seasonic x750 which has 4 x PCI-E connections. Currently I have 2 Galaxy 670's, each with a 8 pin and 6 pin power connection. When I originally set up my system I wasn't sure if I could rin the 8 and 6 pin off of the same cable (1 of the 4 PCI-E connections) so I used 2 connections per 670. Now I want to run tri-sli, so my questions are:

1. Is 750 enough to run these in tri sli with a 3770K?
2. If so, can I run the 8 and 6 pin off of one connection/cable?

750 watts with 3 video cards yes you could do it but you would have little power left over

And yes you can you one cable for one card the cable wont burn out or overload or anything like that
