Bitmain Antminer KS5 Pro 21T

One of the top miners from Bitmain with a hashrate of as much as 21 TH/s. It is used mainly for mining KAS, SDR, BGA and other coins that work with the kHeavyHash algorithm. One of the main advantages is excellent energy efficiency of the 150 J/Th class, which is an order of magnitude higher than average when directly compared with miners used to mine similar coins. At the same time, it has a radically re-equipped cooling system with 4 high-speed coolers.

Equipment Features

The miner belongs to the top line of the Antminer KS5 brand. Consumption is around 3150 W, while the manufacturer provides the ability to overclock and fine-tune the power supply to achieve maximum energy efficiency and optimization for a specific pool in which the miner operates. The maximum noise emitted is 75 dB. The miner can also be used in combination with liquid cooling (immersion in oil), which will additionally compensate for electricity costs by reusing the generated heat. The device is massive, but does not vibrate at all even under maximum load. A high-speed Rj45 port is provided for connecting to the Internet.
