My power supply is a fully modular system but it only has 6+2pin and 6Pin to connect to the video card. My video card needs 2 8Pin connectors for power. In the box the only way i see how this maybe could work is on my PSU. There is VGA1 and VGA2. And they plug straight into the PSU and one cable end to the video card which is 8pin. But its only 1 8pin. So my question is can i have one cable in VGA1 run to 1 video card power input and another in the VGA2 run to the other video card power input?
