each card needs to be connected to the PSU correct? so the PSU came with 3 sata wires because it only has 3 slots for those sata wires (hopefully they are called sata and i am not mistaken). Well one sata is used up, so we are left with only two for the graphic cards. is there any PSU unit that has 4-5 or 6 SATA wire slots so you can connect more than 3 items to it? and also which motherboard do you recommend i purchase i have 3 6970s. i am looking to keep the rig i built the way it is, and just get a new motherboard and a new psu unit for the additional 3 6970s that i have
