what about the power draw ?
1-2-3TH/s gain with 500-600-700 watts or more power usage probably not even worth it to using your mod
It would be great if you can provide some basic information about power draw so members not going to burn down they power supply
or they mining room
...something like :
15TH/s mod / 1400watts / 240volts
16TH/s mod / 1500watts / 240volts
18TH/s mod / 1700watts / 240volts
