Antminer S19 Pro 110 T Bitcoin Miner Machine Review

The S19 series of Bitcoin miner machines from Bitmain got released in February 2020. There are two models in the S19 Bitcoin miner series. They are the Antminer S19 Pro 110 T and the Antminer S19 95T miner machines. The computing power of the Antminer S19 Pro 110T miner machine is around 110 TH/s. The energy efficiency of this miner model is around 29.5 J/TH.

The chairman of Bitmain, Wu Jihan, has also announced that the T19 Antminer series will be launched later. The Antminer T19 series machines are the lower-end variants of the S19 machines. So, the computing power of T19 will be lower than that of the S19 series. The price will be less for the T19 series. The power consumption ratio is going to be high for the T19 series.

Bitmain uses the term “Pro” for their flagship miner machines. So, the S19 110T Pro variant is one of their top-end miner machines. These flagship miner machines are not only known for their excellent performance but also for reliable and stable functioning. Therefore, we will evaluate the Antminer S19 Pro 110T miner machine and see if it can deliver high-end results. The power consumption ratio of this miner machine is 30 W/T as per the manufacturer’s specification.

The appearance of the Antminer S19 Pro 110T miner machine

We have an engineering prototype of the Antminer S19 Pro 110T miner machine. It comes in a simple carton package. There is no logo on the box. It will be due to the fact that this sample is an engineering prototype. You cannot see the contents inside the box from the outside. The first feeling that I got after seeing this package is that the miner machine has become bulkier and heavier. The size of the package is around 68 cm x 42.5 cm x 53.5 cm. The weight of the package is 15.3 kg. If you compare this with the previous version, it is quite strong and heavy.
