Review of Bitmain Antminer S9K, S9SE Bitcoin Mining Machine

Bitmain Ant S9K, S9SE Bitcoin Mining Machine is released in June 2016 by Bitmain. We will be doing an in-depth review of this Bitcoin miner machine. It makes use of the new generation BM1387 chip for mining Bitcoins. It is a 189 bits chip. The computing power of the Bitmain Antminer S9K Bitcoin miner machine is around 11.85 TH/s. The power of this mining machine is about 1172 W. The ratio of power consumption is 100 W/T. This chip is the fifth-generation chip from the Bitmain. It uses the sixteen nanometer FinFet technology from the TSMC. It is a fully customized design, specifically designed for mining Bitcoins. This BM1387 chip is capable of delivering computing power up to 74 GH/S.

This classic Bitmain Antminer S9K Bitcoin miner machine is really an unexpected arrival for many miners.

Generally, Bitcoin mining machines tend to have low life due to the fact that they get outdated because of the rapid advancement in technology. So, the older bitcoin mining machines will find it tough to mine Bitcoins at a good rate. This thing has not changed even with the arrival of mining machines with ASICs.

The Antminer S9 series of Bitcoin mining machines have been in the market since 2016. 11.85 T is the computing power of the first Antminer S9 miner machine on the market. After this model, Bitmain has released many other models in the same series that support different computing powers. There are Bitcoin miner machines in the Antminer S9 series that support computing power of 13.5 T and 13 T. Later, Bitmain released many upgraded versions of many of the Antminer S9 machines. They are the S9i and S9j miner machines. These upgraded miner machines come with a computing power of 13 T to 14.5 T. The power consumption of the newer machines is comparatively less also. Bitmain has also released a miner machine with a water cooling technique for heat removal. It is the S9 Hydro Bitcoin mining machine. It comes with 18 T computing power. The power consumed by this Bitcoin miner machine is about 1800 W.

Even now, Bitmain is dominating the Bitcoin mining machine sector with its different models of high-performance miner machines. In this article, we will review the latest Antminer S9 series machines, the Antminer S9SE and the S9K machines.

Bitmain launched the S9SE-16T and the S9K-14T miner machines in July 2019. The Bitcoin market was at its peak during that time. The price of Bitcoin touched around 90,000 Yuan during this time. It has really helped the market for this miner machine.

Both the Antminer S9SE-16T and the S9K-14T miner machines are short and small when compared to the S9 models in the first generation. The size and weight of both these Antminer machines were the same. The size of the machine is around 32.13 cm x 12.96 cm x 20 cm. The miner machine weighs around 4.56 Kg.

All these 3 models in the Antminer S9 series come with the same power plugs. It comes with three 6-pin power plugs. Each of these mining machines requires ten 6-pin power connectors. It is in addition to the connectors in the control board power supply. There is some difference in the power plug for the new generation miner machines. The material used in the plug is different in the new generation. It is more resistant to heat.

The Antminer S9SE-16T miner machine is the latest one from the Bitmain. There are a few differences when you compare it with previous generation miner machines. You will find a new protective cover in the latest model. You can easily remove this protective cover by removing a screw from the middle. It helps to install the power cord. This protective cover is positioned between the power interface and the control board.

This additional cover demand for more racking processes. But it helps to protect the power interface and the control board of the miner machine. It also helps to give a stylish look to the miner machine after the installation of the power supply.

The power consumption of the Antminer S9K-14T is found to be 1273 W. We did this measurement after running the machine continuously for 24 hours with a stable reception. 14.21 T is the average computing power of this miner machine. The power consumption ratio of the miner is around 89.58 W/T.

The power consumption of the Antminer S9SE-16T is found to be 1378 W. We did this measurement after running the machine continuously for 24 hours with a stable reception. 16.03 T is the average computing power of this miner machine. The power consumption ratio of the miner is around 85.96 W/T, which is lower than the Ant S9K-14T miner machine. This measured value is almost 4 percent lower than the power consumption ratio of the S9K miner machine.
