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.
Bitmain has provided a pearl foam for the Antminer S19 Pro 110T miner machine inside the carton box. This foam ensures sufficient protection to the miner machine during the shipping process. The foam design is in the form of a buckle cover. In addition, there is one more layer of protection in the form of an anti-static cover. The miner machine is wrapped in an anti-static cover.
We will have a look at the appearance of the Antminer S19 Pro 110T miner machine first. This miner comes with an integrated power supply. There are dual fans on the front and the back side of the miner machine. These fans help to remove the excess heat from the system. The machine comes with 10 A dual power interfaces. You can keep this miner machine in the upright position as well as lie down position. The physical size of the miner machine is 37 cm x 19.55 cm x 29 cm. The weight of the Antminer S19 Pro 110T miner machine is around 13.2 kg.
Internal Analysis of the Antminer S19 Pro 110T miner machine
We will disassemble the Antminer S19 Pro 110T miner machine for internal analysis. First, we will remove the three main sections of the miner machine. They are the power supply unit, computing power board, and control board. We will also do a comparative study on some of the parts like fan, shell, heatsink, connecting cables, etc. We will disassemble the Antminer S19 Pro 110T miner machine in the following order.
Disassembly of Control panel
You need to remove the screws of the control panel cover first. It is near the air outlet side of the miner. Now, press and hold the button and push it up to open the cover of the control panel.
Now, you will have to remove the protective cover of the bronze medal. You can see it next to the power supply section. You can move to the next step only after completing this step.
Now, you will be able to see the computing power board and the power supply unit’s connection copper bar. This connecting copper bar of the Antminer S19 Pro 110T miner machine is completely different from the one in the Antminer S17+ 76 T model. They have removed the cross direction. You can see the “+” marking on the copper connection bar. You will also be able to see an increase in the thickness of the copper bar.
Another difference that you can find is the increase in the length of the cable that connects the hash board. It indicates that the length of the hash board has increased. You can see the ports for the cooling fans near the cable. The power supply of the control board is also located here.
Now, you need to get rid of the battle in the front side of the control pane and the control panel’s connecting cable. You can easily pull out the control pane from the air inlet side of the miner machine.
Th Antminer S19 Pro 110T miner machine makes use of a new design in the control board. The color of the PCB is changed from green to blue. The interfaces and the size of the control board in the Antminer S19 Pro 110T miner machine are the same as in the S17+ miner machine.
Control Board’s Interfaces
You will be able to see the SD card – TF card slot interface for flashing the firmware of the miner machine. There will be the IP report button to find the IP address of the Antminer S19 Pro 110T miner machine.
You need to use it along with the ant tool. There will be an interface for connecting the Ethernet cable. You can reset the whole miner machine by pressing the Reset button. If you long-press the reset button, default factory settings will be loaded into the miner machine. There are status indicator LEDs that show the operating status of the mining machine.
Disassembly of the Power section
Now, we will disassemble the power supply unit of the Antminer S19 Pro 110T miner machine. You need to remove the fixing screw first. You can find these screws near the air outlet side. You will have to push the power supply module to remove it. APW12 power supply unit is used in the Antminer S19 Pro 110T miner machine. The conversion efficiency of this power supply module is 95 percent. It is an adjustable voltage power supply. The voltage can be varied between 12 V and 15 V. The nominal maximum power output of this power supply unit is 3600 W. You can get a maximum power output up to 4000 W from this power supply module. You can also see a warning label on the power supply module. The warning label states that you need to disconnect both the power cables of the power supply at the same time when there is a power outage.
So, the Antminer S19 Pro 110T miner machine makes use of a new APW12 power supply module. There are a couple of 10 A power cables for this power supply. The dual input feature of this power supply module helps to reduce the safety risks. It lowers the chances of getting the power cable heated as well as the power socket. You can use the machine continuously for a long time with the power coming from a couple of 10 A power sockets. The size of the power supply module in the Antminer S19 Pro 110T miner machine is larger than the one in the previous versions. The larger size helps to dissipate the heat efficiently. You will be able to see 3 fans in the power supply. These 3 fans help push out the hot air from the power supply. The S17 miner machines make use of 40 cm fans. The power supply unit of the S19 pro makes use of 60 mm fans. So, the fan size is larger. It helps to reduce the power failure rate since the volume of air that gets pushed out will be more.
Dismantling of the Hash Board of the Miner Machine
The cooling system in the Antminer S19 Pro 110T miner machine is a highly-customized one. There are four fans in the Antminer S19 Pro for the removal of heat. These are 1.65 A-rated fans.
A brand-new mold is used to manufacture the chassis of the Antminer S19 Pro 110T miner machine. A one-piece die-casting method is used for the creation of the mold. The S17+ machine makes use of a split design for the chassis. The Antminer S19 Pro 110T miner machine comes with a flat bottom. There are no rubber pads on the bottom of the miner machine. It would be nice to have rubber pads at the bottom. It helps to improve the safety of the miner when they are pushed on to the racks.
There are 3 built-in computing power boards in the Antminer S19 Pro 110T miner machine. These computing boards come in square shapes. You can see the heat sinks on both sides of the board. So, they have implemented a proper heat dissipation scheme for the Antminer S19 Pro 110T miner machine.
There are two heat sinks for a single chip. It ensures the effective removal of heat. The design of heat sink helps to reduce the wind resistance. It also helps to improve the air circulation inside the miner machine. It also helps to avoid dust accumulation inside the miner machine. You can see a pink thermal gel between the heat sink and the top surface of the chip. This thermal gel helps provide good surface contact of the chip with the heat sink. It helps to remove the heat effectively.
Only one heat sink is used on the other side of the board. If you observe the size of the heat sinks, they are gradually increasing from the air inlet side towards the back. This design helps to remove the heat uniformly from the hash board.
Antminer S19 Pro 110T miner machine comes with the latest TSMC 7nm ASIC chips from Bitmain. They use BM1398 chips in the miner machine. There are 114 chips on each of the computing power boards. So, there are a total of 342 BM1398 chips inside an Antminer S19 Pro 110T miner machine. It helps to generate the 100 T computing power for the miner machine. Each of the BM1398 can provide computing power up to 322G. If you see the computing power of the chip in the first generation of Antminer, it is around 180G. This latest Antminer version has almost doubled the computing power.
