Im planning on buying a Corsaitr TX 650W for my GPU( i know thats more than enough i want to crossfire my card later) and as i sawy in a review this PSU haas 6+2 pins pcie-e connectors... Does that mean that the other 2 pins are detachable? like in the main atx 20+4 conector? If so can i connect one of these to my card leave the 2 pins aside? Does the Corsair TXEU 650W version of this PSU has the same conectors?What´s the difference between the two of them?
