Am I understanding right that you link the boards together? So basically I'd have 4 boards from one assembly and 1 board from a second assembly linked and powered by the 1300 and the remaining 3 boards on the second assembly linked and powered by the 850?

That's correct.

The boards are electrically separate so the PSU doesn't care. Just do NOT power the same board (ie two touching PCI-E ports) with different PCI-E ports or you'll cross load the PSUs and mess up both.

Ok cool I should be good to go then, assuming my current thinking is correct as below:

- 200 W per board without overclock
- 250 W per board with overclock
- that puts my 850W PSU at 600-750 W when powering 3 boards
- puts my 1300W PSU at 1000-1250 W when powering 5 boards
- 1A x 12v max X 2 (max) for the controller = +24 W, will probably run this from the 850W PSU**
- Huh

- profit (hopefully?)

**This assumes molex connectors on a PSU run on the 12V rail... does anyone know if they do? If not, which rail do they run from? Pretty sure its the 12V though, otherwise GPU manufacturers wouldnt ship molex-to-pcie adapters...
