Proliant DL380 G6 GPU

Hello people,

I have a Proliant DL380 G6 and I want to build a Graphics card into it. To be specific, it is a GTX 960 from Asus. The card When I now want to build it in, I am pretty shure I need a pcie slot riser, which one would you recommend? And also, can I just plug the card in on the SAS Connector A or B on the motherboard? If no, how would I get power to the card? I post a picture of my server below.
