Figured I'd post this here for people who don't follow the S7 thread.
Decided to "make a thing" to power my S7s 
. Hope some of you will appreciate this!
2X 2000w server PSUs sharing the load of the 3 S7s. Will shortly be replacing the PSUs with the 2500w versions since I'm actually pulling 4400w DC from them right now, which is 200w over their rating on each.
I've adjusted the voltage output to 12.6v on the PSUs.

what's the purpose of the busbar, and not just connecting the PCIe wires directly to your breakout boards?
obviously the load-sharing provides slightly better stability/overhead, but for ~$20 of extra materials and at least an hour of added assembly adding another PSU seems simpler
