1080ti looks like a beast on equihash coins.

How are people finding the power use and cabling?

What I mean by 'cabling' is that each 1080ti needs two 8 pin cables. Most 8 pin cables are 2x8 (or 2x 6 +2) pin - that is, they have two 8 pin connectors on the one cable.

Are you able to use just two cables for a 1080ti, with one 8 pin connector to power half of the 1080ti, BUT then use the other remaining 8 pin connector on the same cables to power, say, a 1070?

Getting the most (safely) out of your cables is important if you're running out of sockets/cables on your PSU!
