Bitmain Antminer S17+ For Sale

The computing power of Bitmain Antminer S17+ is as high as 76TH/s, with strong performance. Through the optimization algorithm, the stability is stronger, and the new fan speed regulation logic is used to effectively reduce the chip temperature and reduce the noise of the fan.

 

Bitmain Antminer S17+ 76T was released by Bitmain in October 2019, and Antminer T17+ was also released at the same time. The two new mining machines were officially released in October, attracting many miners to choose.

 

Bitmain Antminer S17+ can be divided into five models according to different computing power: 76T, 73T, 70T, 67T, and 64T, with a power consumption ratio of about 40W/T. What is the actual performance of the Bitmain Antminer S17+?

Bitmain Antminer S17+ Appearance

Since Bitmain released the S17 series of Bitcoin mining machines in 2019, the outer packaging size of the Antminer S17 series has been kept uniform, 486*388*265 industrial carton packaging, with manufacturer information and the Antminer logo on the box. ,

 

The standard value of logistics warehousing, the specification, and model of the mining machine, and the barcode identification code, including the weight of the box is about 11KG.

 

The only difference between each model is that a label is added under the bar code of the mining machine, which has been certified by the technical regulations of the Customs Union to ensure product safety, unified standards, and certification of requirements.

 

The interior is encapsulated by a customized Tiandi cover pearl foam mining machine, and there are gaps around the periphery to facilitate the pick and place of the mining machine. The inside of the box is also equipped with a mining machine qualification certificate and multi-national language instructions, which is convenient for miners in various countries to understand the detailed operation.

 

There is also an anti-static shield inside the miner for enhanced protection. The net weight of the Bitmain Antminer S17+ 76T is 9.8KG and the size is 298*178*304mm. At a rough glance, the Bitmain Antminer S17+ is not much different from other S17 series mining machines.

 

The mining machine uses an all-in-one machine design with front and rear dual exhaust air and parallels dual fans. The mine can freely choose the placement method according to the size of the rack, adapt to the size of different racks, and choose to place the Bitmain Antminer S17+ 76T upright or lying down.

 

Bitmain Antminer S17+ 76T Detailed Review

Antminer S17+ 76T adopts ultra-high integration, the whole machine is an integrated design, the changes of the mining machine need to be analyzed from the details, we can analyze the overall details of the mining machine by dismantling.

 

Dashboard Details

 

The control panel cover combines the design of Antminer S9SE and Antminer B7, combining buttons and screws, abandoning the sliding cover design of B7, and changing to a flip cover design, which is much more convenient, remove the screws, Press and hold the button up to open the lid.

 

The various connecting lines at the position of the control board are neatly arranged, all the connecting lines have been standardized, and the traditional cable connection is used between the control board and the computing power board.

 

Location details of the power connection tabs

Bitmain Antminer S17+ 76T adopts a fully wrapped body design, so the cable of the machine is not exposed. Due to the change of the chassis, the cover of the control board and the cover of the power supply are separated, so that an additional shell is installed at the position of the power connection piece, and the shell is fixed with snaps and screws.

 

After removing the shell, you can see that the connection between the power supply and the hash board is to use two copper plates to connect the three hash boards.

Power Details

The Bitmain Antminer S17+ 76T is equipped with an APW9+ power supply, providing 12.3V, 14.5-21V DC voltage, rated power of 3600W, and a maximum rated current of 170A.

 

The APW9+ power supply PFC and PWM output of Antminer S17+ 76T can extend the life of components and enhance reliability, and use three fans to supply air to provide active cooling for the power supply. The APW9+ power supply has a compact structure and dual inputs can reduce the power consumption and safety risks of heating the input cable socket.

 

fan details

The fan is the heat dissipation guarantee of the Antminer S17+de. The whole machine uses four fans in double parallel to provide heat dissipation, and the case is fixed in the form of snaps and screws.

 

Bitmain officially said that the Antminer S17+ 76T adopts a deeply customized and optimized cooling solution, which reduces losses through refined temperature control, making the operation of the miner more efficient and stable. This is reflected in the fan, the air inlet, and the outlet of the miner. The current of the fan is different.

 

The current of the air inlet is 2.7A, while the current of the fan at the air outlet is 3.14A, which is not much different but reflects the refinement of the design.

The baffle where the fan is installed uses a relatively complex casting process, and a sponge is used as a buffer material on the contact surface with the hash board to reduce the impact of the mining machine on the hash board and the casing during transportation.

 

The fan power cable process also takes into account the anti-scratch situation, adding protective materials to the contact surface with the chassis, and the fan extension cables are reinforced with cable ties.

 

Dashboard details

After disassembling the fan, you can see the computing power board. The Antminer S17+ 76T has three built-in computing power boards, and the three computing power boards are installed in the chassis through the fitted card slots. Each hash board carries 65 7nm chips, and the three hash boards have a total of 195 chips.

 

Both sides of the hash board are covered with stainless steel heat sinks of different lengths. The heat sink on the air inlet side is shorter and more dispersed, and the length and density of the air outlet side are greater. Maybe this is the depth of the Antminer S17+ 76T. Customized and optimized heat dissipation design, of course, more details are reflected in software control.

Antminer S17+ 76T shell details evaluation

The chassis of the Antminer S17+ 76T is no longer a one-piece die-casting structure but is divided into two parts. The two sides are formed separately and then connected through the card slot to form the intention. This structure makes the miner lie flat. As a result, the miner will be tilted a little,

 

This explains why there are four pads included in the package. The chassis is made of aluminum alloy, and it is uncommon for the inner wall to show a rainbow-like color.

 

Measured data of Antminer S17+ 76T

We tested the Antminer S17+ 76T for more than 24H, the test environment temperature is about 23.8℃, the noise value is about 56dB, and the power-on voltage is 226V.

 

The power consumption of Antminer S17+ 76T is 40W and the noise is 73dB. When starting, the network cable light is on, and the status light is red. When starting, the miner will automatically adjust the frequency. After 3-5 minutes, the miner will run normally.

After the miner runs for more than 24 hours, you can see that the control page shows that the computing power is 78.5T. At this time, the temperature of the inlet side is 24.8℃, the temperature of the outlet side is 50.9℃, and the temperature of the outlet side of the power supply is 38.7℃. The temperature in the middle of the chassis was 31.7°C, and the temperature in the middle of the power supply was 33°C.

 

Each Antminer S17+ 76T has four PCB board temperature sensing modules and four chip temperature sensing modules distributed on each hash board. The PCB board temperature value is in the range of 39-61 degrees, and the chip temperature value is in the range of 57-80 °C.

 

The power consumption of the Antminer S17+ 76T is 3100W, and the noise value at close range is 79dB. The 24-hour receiving computing power of the BTC.com mining pool is 76.67T, and the computing power reaches the standard. The final test power consumption ratio of Antminer S17+76T is 40.43W/T.
