I am trying to see if my rig can support a RX Vega 64. This card requires two 8-pin connectors, but my PSU only has a 6+2 pin, 6 pin, and 4 pin connectors available, all seemingly separate wires. Can I take the 6 pins from my 6+2 connector and the remaining 6 pin and 4 pin connector and use those to substitue for the two 8 pin connectors needed for this card?
