Well my PSU has 2x6 pin connectors and 2x2 pins connectors but I accidentally ordered a 6 pin GPU white sleeved extension
when my GPU needs a 8 pin.
PSU - EVGA 500W BRONZE CERTIFIED PSU.
if you have two 6-pin cables then use a dual 6-pin to single 8-pin adapter
I have a 6+2 on my PSU but the white extension i ordered is only a 6 pin when my gpu is 8 pin.
also im surprised that psu does not have a 6+2 pcie cable
