New gtx 1080 issues

[c26steam]

I just got a gtx 1080 and it needs two pcie cords plugged into it but I only had one in my old gfx card and I looked on my mother board and I saw only one port to plug in a pcie cord

 

[sizzling]

The motherboard has nothing to do with it, its the psu you need to connect it too. What make and model psu is it? If it doesn't have a second pcie power socket it means the psu isn't good enough.
