930w from the wall.
System : ~75w
=
855w
Split that on six gpus: ~142.5w per gpu from the wall @30Mhs
Still really good numbers. People should stop staring at gpu-z numbers because they are pretty much irrelevant.
The wattage presented in gpu-z is what the gpu itself are pulling, not the whole card.
The GPUZ number is 69W, the actual power consumption is 142W from the wall, or 125W for the card, so the difference is about 55W.
So many more factors to include in this.
You've got PSU efficiency, type of gpu, the way the rom is modded (power draw from the pcie cable or the slot (it makes a difference!)), the risers also pull some power, not every cpu is even efficient, same goes for the memory, etc...
