Can anyone comment on the power consumption for the RX580 cards. I have two rigs each has 6 RX580 and both are dual mining ETH+LBC (Eth: 176 Mh/s + LBC: 510 Mh/s). Each rig consumes about 1020 Watts reading from the wall-meter while GPU-Z reads less than 130 Watts for each card. I think they should all be around 6*130 + 70(system) ~ 850 Watts total. My setting (-cclock 1150 + -mclock 2100 -cvddc 870 -mvddc 870)
