To save yourself some cabling in the future, you can split one power cable to two of your 480s easily. I use a 6pin to dual 6+2 pin adapter and the builds are much cleaner. Very nice job though.

Yea, I thought about that too, but then I wanted to future proof my rig, in case future cards require (2) 6pins or (2) 8pins each, then I am ready for them, just need to swap out the cards and good to go with no modification needed. Since right now, each GPU has a spare 6+2 PCIe as can been in the photos of the rear. I would hate having to redo my cables in the future if the newer cards requires more PCIe ends, which is the reason why i took this step.
