It seems most, if not all blower style 1080 cards and a handful of multi-fan cards have only 8 pin power.
Most after market open air cooled GPUs seem to have 6pin + 8pin. I am thinking that the extra 6pin is there to supply extra power for multi-fan open air GPUs and possibly RGB.
On my MSI 1080 Seahawk EK X and it has an 8 pin as well as a 6 pin connector on it, it also has a RGB header and a fan header, though neither are in use as the GPU came stock with an EK Water block.
MSI also makes another Seahawk non-EK version. This is a hybrid blower + AIO cooler, though this only has an 8 pin. Both of the 1080 Seahawks have identical specs, in terms of GPU and Memory overclock listed.
I have a hypothesis that MSI uses one of two standard cards and that my GPU does not require the extra 6pin power connector. It would be nice if I could verify this some where.
