Hi,
I recently purchased GeForce GTX 1070 Ti card. My 850w power supply has several 6-pin connectors. The card has two 8-pin connectors. I have a 6-pin to 6+2 cable, and a 6-pin to 8-pin cable connected, but still getting error message "Please power down and connect the PCIe power cables for this graphics card".
Please advise fix. Bob
