The graphic card demands 2 power cords to it in order to work, one 6 pin and one 8 pin.
When my PSU was delivered I was given a large set of cables (PCI-E 6+2Pin), however I never got a 6 pin from anywhere.
- Am I able to use those 6+2 pin-cables in order to set my 6 pin up to the PSU. (See the outputs in the link above).
Yes of course that's normal, 6+2 pins are standard now in PSU's, they are used for both 6 and 8 pin connectors. Just connect two PCI-e connectors to your PSU and insert one 8 pin and one 6 to your GPU, easy peasy mate.
