might be an easy 1 but im unsure so ill ask anyway. i have a 990 fxa ud7 with a atxp4 sata connection on the board. question is can i use the cable i power my hd with to also power the board or should i run a separate cable? the cable running to my hd has 3 sata 15pin connections the hard drive being at the very end. 3 280x gpus if that makes a difference.
