I am having trouble getting my recently purchased GeForce GTX 1080 to work. I am receiving the following message on boot: "Please power down and connect the PCIe power cable(s) for this graphics card." I suspect it has something to do with not getting enough power from my PSU. The GPU was provided with an 8 pin male cable that splits into two 6 pin females. My PSU did not have two free 6 pin male cables, so I purchased an 8 pin male to 6 + 2 pin male adapter cable thinking that would be sufficient. Unfortunately, that did not fix the issue. What should I do next? Am I supposed to purchase two 6 pin male to 6 pin male cords to connect to the 8 pin male cable that splits into two 6 pin females?
