yes it will work, it as the 8pin/8pin configuration setup so all you have to do is remove one of the 8 pin plugs and install the included 6 pin plug, adjust it as per instructions. if the video card came with 2 6 pin connections then you would need to order/buy the 2nd 6 pin seperate for the power link.
if you check out my mod rigs link you will see that it keeps it nice and tidy, dont forget to +1 my rig
thank you
