I have purchased many cables to properly power my graphics cards in my setup but they did not all work as easily as this dual PCIe cable. It was a very easy install and very clean wiring. The dual PCIe cable is long enough to power the 8-pin GPU and 6-pin adapter simultaneously, with extra length to keep it away from the GPU. I used an Evga 1000W G1+ to power my rig by connecting the standard end of the PCIe cable to the PSU's PCIe connector and the other (6+2) 6-pin end to the dual PCIe cable connected and then connected the dual PCIe to the climber. and GPU. I will order more
