what do you mean your video card doesnt have a port to the outside ?
that doesnt make sense
heres the rear of that cardhttp://www.hisdigital.com/UserFiles/product/0128_08_1600.jpg
and the cord is connected to the motherboard through the back of the case?
i seriously hope you dont mean directly to the motherboard
you do mean to the graphics port on the outside of the case at the rear?
