Lower your voltage. As low as you can without crashing.
I do that and saved some energy.
But my problem is not because of the energy expenditure is because it reaches the temperature of 85 ° c
Dude, watts = heat. Lower your energy expenditure ffs.
Hey guys, can you also share more details on power consumption on wall? I did not found any details on a 6x GPU rig or single card .. i just want to know if a 1200w psu is still enough or i should go with 1300w or 2x 750w 
thanks!
thanks!
I'd always get an EVGA 650 + http://www.parallelminer.com/product/hp-1200-watt-power-supply-kit-for-gpu-mining-platinum-94-zec-dash-eth/
Doing 30MH on the RX 570 Pulse with -200mv (775mv core voltage). Pulling 95 watts at the wall 
775mV running enough juice to keep the core clock high enough to hit 30 is very doubtful. It's not -impossible-, but it just means he hit the ASIC quality lottery on ONE card, good for him.
