So I got a new Asus Strix Raid Pro sound card today for my new Tiamat 7.1 v2 headset but when i went to put it on my asrock z97 anniversary motherboard I realised it needs a 6 pin pcie connector and my evga geforce gtx 960 is using the only two that my 550w psu has. What can I do please i'm not very good when it comes to pcs. Does this mean I need to upgrade my PSU for one that has more than 2 6 pin connectors or is my psu fine and another solution is possible?
