Howdy folk. I'm in the process of trying to help a friend out who recently purchased an EVGA GTX 1070 FTW edition. After doing some research on the model he bought, it appears he picked up quite the power guzzler when compared to other 1070s in EVGA's line. This particular model has two 8 pin PCI-E connectors. When doing a little research, it appears that he has a power supply strong enough to power this thing, but we're not having the best of luck getting this thing going. I'm not the best when it comes to computers, so I'm hoping you guys can point out what I'm doing wrong and help steer us in the right direction.

My friend has an OCZ ModXstream 600W Power supply. ( Heres a link to a full review for this PSU http://www.overclockersclub.com/reviews/ocz_mxs_pro_600w/ ) I feel like this guy should be powerful enough to run the video card but clearly something is wrong. Unfortunatly, my buddy does not have all the original cables for his PSU so i tried using some of my own cables. In the first attempt, we used two 8 pin to 6 pin connectors (8 pin side connected to the video card and 6 pin ports connected to the PSU side) and this configuration did not work. When we try to power on the computer, it turns on for a split second and then turns right off. I tried one last attempt and used the 8 pin to dual 6 pin splitters that are provided with the video card and used 3 6 pin connector cables and 1 molex to 6 pin converter since there were not enough 6 pin ports on the PSU. This combination also didnt work.

I have two questions for you guys. my first one is if my buddies PSU (OCZ MXSP 600W) is actually powerful enough. The second is if I'm connecting this thing up the wrong way to his PSU? I see that there are two red 8 pin ports on the unit, are they the only ones powerful enough to run the video card? If i buy two 8 pin PCI-E power cables and directly plug them from the video card in to the red ports, will this sucker power up, or am I working with a PSU that isnt capable of running this thing at all? thanks again for your help. Ill try and provide any additional information that you guys may need.
