I've my GPU plugged to the PSU with a 8-pin and a 6-pin connector
but there's this 6-pin slot which the MB's Manual describes as "used to provide power to the graphic card" i can plug one of my PSU's 6-pin connector to it but i donno
do I have to?
 
no, just plug the cpu 4/8pin power connector and leave the other one and only if the pc does not boot then use the other connector, i believe the 6pin for gpu's on the motherboard is for multiple cards that dont use pci connectors from the power supply
