Antminer S19 miner was released on March 23, 2020. It is equipped with a 7nm process chip and is the third generation machine of Bitmain 7nm. According to official data, Antminer S19 miner has a rated computing power of 95TH/s and an energy efficiency ratio of 34.5J/TH±5%, making it a well-deserved top ASIC mining machine.
The Antminer S19 miner is slightly larger in appearance than the S15 and S17. The bare metal size of the Antminer S19 miner is 400×195.5×290mm, and the net weight of the whole machine is about 14.4 kg.
In terms of appearance, the Antminer S19 miner adopts an integrated design of "chassis + power supply". Antminer S19 miner has a very high level of integration. The power supply and control board are all integrated in design, which is also for the convenience of operation and maintenance, and it is more convenient to put on and off the shelf. It can be freely placed horizontally or vertically according to the actual needs of users.
The overall design of the Antminer S19 miner follows the previous two generations of mining machines, and adopts a dual-tube design, so that the mining machine can better dissipate heat from the hash board during operation. There are two fans in the front and rear of the miner, which are the air inlet and the air outlet.
The Antminer S19 miner fan is covered with a metal grille, which can prevent users from being injured by mistakenly touching the fan, and at the same time prevent foreign objects from being hit by the high-speed rotating fan on the hash board and damage the miner.
According to the actual calculation and feedback from the mining machine operation and maintenance personnel, the Antminer S19 miner is a model with the ultimate computing power and power consumption. As a model with a low long-term power consumption ratio, the Antminer S19 miner enables miners to mine with a stronger ability to resist risks.
