I think this is the first non-officiel antminer s7+ in the world,

this monster is composed of 3 antminer S7 from bitmain + S5+ board with custom modifcation of the s5+ firmware.
With more 7200WATT of power, 540AMP, Frequency to 900MHZ + 12.5 input voltage, the maximum TH touch average for 5 second 21TH/SEC
But this make noise like big fly plan on the startup. Look like this !
