That is the same P# I ordered as well. Works good, but needs a custom pcb due to the different pin pitches. I was able to cram it into a regular proto board with some tweaking
The 6 pin mini-fit jr connectors I bought are not pci-e, one pin is square, but the female socket on the gpu is rounded. These came from a batch of GPUs. Once I realized the mistake in connectors I ordered I cannibalized the 4 pin molex adapter cables, using new pins from digi. Most cards I've ordered come with them. The +2 P/N is wm7263-nd, it fits properly but is missing the little ridges that make it mate on the proper end of the 6 pin connector.
Frozencpu.com sells the proper 6 pin, but I haven't found the right one on digi. You can see the two types, check to make sure you get the right one. I've never seen a supplier for the proper 8 pin pci-e plug. I lucked out and my dual-x gpus came with dual 8 pin gpu power adapters.

The entire chassis had engineered cooling to run on one huge fan or something. I took one apart to check out the heatsinks and figure out the best orientation for a fan, pretty sure I'm going to go with two nice delta fans while running pairs of these stacked so air flows through horizontally. If all my gpu's come with pci-e power adapters this will be a super cheap power supply!
