The AX1200i is a bit of a pain in the ass with regards to cabling. It comes with two double headers and four single headers. While this is 8 PCIE total, it uses up six of that PSU's 8-pin sockets, when it could be 4. Not a problem for a 1080ti rig, but a real pain for 1070/ti rigs.

PS: EVGA SC BLACK is my favorite 1080ti - low heat, high hash, low power and a very small footprint.
