The Bitmain Antminer S7 was introduced to the market in 2015. It has since become one of the most popular Bitcoin hardware miners and dominates the market courtesy of its low power consumption compared to the S5.
The power supply unit recommended for use the S7 is the 1600 watt APW3. This power supply unit is by far one of the best available in the market. It is precisely designed for Bitcoin mining.
The miner can run even the most potent mining hardware – the Antminer S9. It, however, requires a minimum of 205 Volts to operate. The optimal power consumption makes it the most efficient bitcoin miner.
The efficiency of the S7 depends on the effectiveness of the power supply used and the ambient temperature. But, at room temperature of about 25 degrees Celsius, the S7 produces about 1300 watts. At this point, you should note that every generation of the Antminer is near twice as efficient when compared to its predecessor.
