I am new to mining, so have a newbie question! I have six GTX 1070 GPUs. I allow WinMiner to select the best coin, and it happens to select ETN. With a slight overclock on the RAM, I get a harshate varying from 610-641 h/s, depending upon the card. The GPU utilization is 100%, however the GPU power is only 45%. This is consistent with KillAWatt, which report 300W for a EVGA 750W PSU being used for three cards. My question is why only 45% power? I used some GTX 1080 Ti GPUs the other day, and they were using 100% power.

Ideas? Is this normal, or is something screwed up in my setup?

TIA
