First, we need to look at the different changes that Bitmain has introduced in this flagship miner machine. We will do the analysis by dismantling the miner machine.
Details of the Dashboard
The design of the Antenna B7 and the Antenna S9SE is included in the control panel cover. It is possible with the help of the buttons and the fixing methods for the screws. They have abandoned the sliding cover design which was used in the B7 slot. Now, it is a flip cover design. It makes it more convenient. You need to remove the screws and press and hold the button. Lift it to open the cover of the miner machine.
There is proper arrangement for the different connecting wires of the control board of the miner machine. The connection between the control board and the computing power board is the same as in the previous models.
If you look at the function keys and the interface keys of the miner machine, it is similar to the previous model.
Location details of the Power Connector of the Mining Machine
The Antminer S17+76T Bitcoin miner machine comes with a fully wrapped body design. So, all the cable connections in the machine will not be seen externally. In addition, there is a change in the design of the chassis from the previous models. This new design provides a separate cover from the control board as well as a power supply. You can see an additional shell in the place of the power connection piece. This shell is connected with the help of the screws and the snaps.
Once you remove the casing, you will be able to view the connection between the hash board and the power supply. There are three hash boards in the Antminer S17+76T Bitcoin miner machine. This miner machine makes use of two bronze medals to connect all three hash boards. Cross-type connection is used for the power connection using the bronze medals. You can see the positive and negative markings on the bronze medal.
Power Details of the Antminer S17+76T Bitcoin miner machine
This miner machine comes with an integrated power supply. The power supply used in the Antminer S17+76T Bitcoin miner machine is APW9+. It is capable of providing 12.3 V, 14,5 V to 21 V DC. The total rated power of this power supply unit is 3600 W. This power supply unit is rated for a maximum current of 170 A.
The dual-channel PFC and PWM output of the APW9+ power supply helps enhance the life of the components in the module. It helps to enhance the reliability of the power supply module. There are 3 fans inside the power supply unit for removing the excess heat from the module. It helps to ensure that the temperature inside the power supply never goes beyond the recommended value.
The design of the APW9+ power supply is really a compact one. The dual input feature of the power supply helps to lower the power consumption. It also helps to improve the safety of the unit since the chances of the power cables getting heated are very less.
The weight of the APW9+ power supply is 3.2 kg. So, one-third of the weight of the Antminer S17+76T Bitcoin miner machine is due to the power supply.
Details of the Fans
The Antminer S17+76T Bitcoin miner machine comes with a heat dissipation guarantee. So, we will evaluate the same. There are 4 fans used in the Antminer S17+76T Bitcoin miner machine for cooling the miner machine. It is fixed to the case of the miner machine with the help of screws and snaps.
According to the official statement from Bitmain, the Antminer S17+76T Bitcoin miner machine makes use of a highly-customized heat removal design. It helps to lower the losses of the machine and also helps to achieve better temperature control. Thus, this design will help to improve the performance of the Antminer S17+76T Bitcoin miner machine. We can see it in the design of the fans. The current consumption of the fan at the air inlet side is around 2.7 A. The current consumption of the fan at the air outlet side is around 3.14 A. The difference is current is not that big. But it helps to improve the cooling design of the system.
Bitmain has used a complex casting process for the baffle of the fan. In addition, they use a sponge material as the buffer at the contact surface with the hash board. It helps reduce the impact on the hash board during the transportation process. It also helps to protect the casing of the miner machine.
If you look at the power supply cable of the fan, you can see that they have considered the Anti-scratch design. Wherever the power supply cable makes contact with the chassis, a protective material is added. Cable ties are also used to reinforce the fan extension cables.
Details of the Hash board
You can see the computing board of the Antminer S17+76T Bitcoin miner machine after removing the fan. There are 3 built-in computing power boards in the Antminer S17+76T Bitcoin miner machine. You can also see 3 computing power boards that are connected to the chassis through the card slots.
There are 65 numbers of 7nm ASIC chips in the hash board. So, the total number of chips in an Antminer S17+76T Bitcoin miner machine is 195.
There are stainless steel sinks on both sides of the hash boards. The length of these two heat sinks is different. The heats sink near the air inlet side is smaller and arranged in a scattered fashion. The heat sinks on the air outlet side are slightly larger and dense. The difference in size helps to provide better cooling for the miner machine.
The Antminer S17+76T Bitcoin miner machine’s chassis does not make use of a single-piece die-cast structure. It comes in two parts. Both these sides are formed separately. A card slot is used to connect these two sections. You can see a protrusion in the middle of the miner. This protrusion makes the Antminer S17+76T Bitcoin miner machine lie flat. This slope in the design is the reason why they have provided 4 small adhesive pads in the package. Aluminum alloy is used for making the chassis of the Antminer S17+76T Bitcoin miner machine. You can see a rainbow color on the inner wall of the chassis.
