only quick info for all original Z800 users, successfully running 2x X5687 + 2x R9 290 OC with stock 1110W PSU (no additional psu needed).

power to GPUs
V-G1 6pin -> 8pin
V-G2 6pin -> 8pin
1x molex -> 6pin
1x modified CPU power cable -> 6pin (1x +12 CPU0  1x +12 CPU1)
(Obsidian Series 800D 8-Pin Motherboard Power Extension Cable Corsair CC800D-8PIN)

all stable

quick info:

i was searching for max power output thought 6pin GPU connector and i find this pdf
http://www.nvidia.com/content/quadro/maximus/di-06471-001_v02.pdf
where they use  6-pin to 8-pin adaptors for tesla and quadro fx5xxx in Z800

because i want to try SLI GTX980 and dont want case full of molex conversion cables


Z800 board is not GeForce SLI certified so you will need to use an SLI hack to make it work. I did this back in the day on an Asus P5Q-E board. As far as powering them if you're using the standard Z800 case you can run dual 5.25" drive-bay PSUs (1 for each GPU) I'm doing this for my dual AMD R9 280X set up as Crossfire requires no certification. Here is a picture of my set up:



Can you share pictures of your custom cable and how you have it connected?
