My Crossfire came with 4 of the holes "plugged" with a plastic insert. I have a Tagan Piperock 700W PSU that has a splittable plug that can be wither 4 or 8 pin depending on whether or not I slide one 4 pin onto the other or not.
Should I pull out the plug thing and connect all 8 pins from my PSU? Why are 4 of the pins plugged to begin with? I am afraid that it is that way for a reason and don't want to harm my mobo..
Appreciate any help on this.
