your wont need that cable.that cable is for older power supplys that dont have any pci power plugs. your power supply has one.

it the one on the top of the photo it a 6 pin plus 2. the plugs are keys and can only go one way into the top of the card.
pci video card some of them need more the 75w to run. the pci slot cant give the card all the voltage in needs so vendors have to use one or two extra power plugs for there power hungry cards.
