So I had an odd day today building a new rig. I got the MSI Z270 Gaming M7 Motherboard with an i7 6700k and a Corsair 750M power supply. One thing I noticed was the CPU power on the motherboard requires and extra 4 PIN to which my PSU does not have. Doing some research everyone said it will not power on but it did for me and everything seems to work just fine. Is the extra 4 PIN for 7th Gen CPU's? That would be my wild guess.
