So, I put in an order for the mobo, the box, and the server style PSU.  I noticed that it's 2200 watts (240v), but only 10 6-pins.

I have plans for this to power 8 1080tis (once I find them).  All 1080tis together is just 1600 watts on neoscrypt, well below the 2200 watt maximum, but it only comes with 8 usable 6 pins, since the board itself needs 2 to power on.

Anyone know what I should do in this situation?

I found a 6 pin to two 6+2 pins adaptor/splitter that should work, but that seems awfully dangerous. 

Anyone have any idea how best to use the server PSU with a host of 1080tis?
