also the PSU side has all 8 pins available, there is a metal pin inside every connector slot on the PSU.
there is also one extra 8 pin connector on the psu which can be used either as a second 8 pin eps for motherboards with two CPU's (server boards) or a PCIe power.
it is located on the top row next to the sata/molex ports... you will have a total of 5 PCIe's left over if using only 1 of them for the 8 pin mobo cable.
(so 6 PCIe connectors total on the psu all 8 pin, one has to be used for the mobo power, or two if you have a server board)
...third from the right, notice the psu side has an 8 pin block but two pin slots there are unused with the cables they send with the 760wXP2
this is the same as the PSU connector side, all pins are there, if the user uses an 8 wire 8-pin connector or a 6 wire 6+2-pin it's at the user and the cable's discretion...
