I have a PNY GTX 770 and these power connectors are weird!

So my PSU is 750w and has 1x8 pin PCI-E Female slot. The Y-splitter the 770 came with is 1x8 pin Male to 2x6 pin Female. The connections on the 770 are 1x8 pin Female AND 1x6 pin Female.Do I need to have both slots on the GPU filled? Do I need some fancy Male to Male adapter?
