Hi everyone i require some help concerning my current and future setup. As the title suggests im the happy owner of a p9 psu, i also have a Asus gtx 580 dcu 2. Now first issue is that because the gpu takes 2 x 8 pin power i have to use 2 cables connected to 2 pci-e slots on psu, i would like if possible to use one pci-e slot to power 1 card. So i require a pci-e cable with 2x 8 pin power, if i can do get hold of a couple of these cables i can free up a pci-e connection on the psu for a gtx 580 sli set up. At present im using 2 out of the 3 psu connections on 1 gpu so sli is not going to happen. I do have the option of making the cables myself but its a time consuming ballache procedure. 1 do be quiet make these cables if so how much ? 2 will 1 pci-e connection power my gpu ? Any thoughts or help would be massively appreciated.
