That video card has two 6-pin connectors? Use the one that's on the PSU (6+2) and for the second one use a free molex and an adapterhttp://www.newegg.com/Product/Product.aspx?Item=N82E16812201004
You should have an adapter in the card's package.
For the mobo you have a 4+4 Pin EPS 12V (don't use that for the video card!) and the 24-pin ATX.
