Greetings. I would like to know if anyone knows the configuration of the positive and negative pin sides that the eight pin PCI connector that goes into the Toughpower 1250W PSU to the GPU's. On most PCI PSU configurations, the side that is near the connector clip (pin holes 5-8) are for the negative side. Then, pin holes (1-4) would be for positive. Is this correct for this unit? The reason I'm asking this, is all cables (except for SATA data) are custom made for they had to be built for the Cooler Master HAF Stacker (935, 915R and 915F) cases are poorly made to fit and reach components, the thing is 42" tall when put together. I have an Asus Rampage IV Black Edition motherboard, an Intel i7 4930K CPU, two Asus R9 280X video cards, everything is liquid cooled, 5 hard drives (4 in RAID config) one is a 500gb VelociRaptor, SSD plus the rest of the accessories. I have far to much invested in this build plus the time, to make this mistake. Too long of story as to why I don't have the original cables that came with the unit. Thank you everyone for your help, highly appreciated.....
