I am upgrading an Alienware Aurora R8 which came with a Nvidia 1070 graphics card that has a single 8 pin connector on it. However, when I inspected the system, the motherboard also has an 8-pin connector on it as well labeled GPU PWR. The original power supply was running an 8 pin connector to both the GPU and the motherboard's GPU PWR connections. I am throwing in a RTX 3060 which has one 8 pin and one 6 pin connector (yes I am also replacing the power supply at the same time). Am I correct in assuming that I should connect the 8 pin and the 6 pin directly to the card and the 8 pin to the system board is not needed? Or how should the power be run to this card in this instance?
