About MicroBT
One of the top manufacturers of Application Specific Integrated Circuits (ASICs), Shenzhen Bit Microelectronics Technology (also known as MicroBt) was founded in 2016. The company develops and offers assistance in blockchain technology, cloud computing, and artificial intelligence in addition to producing and designing high-end 28nm/16nm/7nm working chips.
Its specialized chips and auxiliary products are protected by separate intellectual property rights held by the MicroBT company. They are one of the biggest ASIC miner manufacturing companies.
Their flagship product, the Whatsminer, is Plug and Play Bitcoin Mining Hardware that enables end users to immediately begin mining coins using the SHA-256 algorithm and partake in the digital currency gold rush. The simplicity of use, even for novice miners, is what made this popular.
Overview of MicroBT WhatsMiner M20S
A new multipurpose device is the Whatsminer M20S. The benefit of an all-in-one machine design is that it has fewer wire connections, a more streamlined and attractive appearance, and is easier to use and operate. It is a part of the ASIC mining apparatus, which consists of three boards for computing power and one main control board. The mining machine has a number of buttons on the outside, including buttons for IP address feedback, network cable interface, reset, and status indicator configuration. , the button configuration part is no different from the traditional mining machine, the power supply of the mining machine is integrated with the body, saving the horizontal space of the mining machine.
Specifications
This particular model of the M20 series has the highest hash rate. The power consumption ratio is 48W/T. It is a little on the high side in terms of power consumption (3200W), which lowers profitability. It can mine about 40 coins using the SHA-256 algorithm. Bitcoin (BTC) and Bitcoin Cash (BCH) are the most profitable coins, though.
It uses a conventional single tube design and comes with a single 16A 3×1.5mm power cord (Note: the miner power plug is also only for 16A power cord interface; the power plug is specifically for 16A jack). It measures 390x158x240mm and weighs 11.4kg.
Fan and Air Circulation
The control board’s side is where the air inlets are located, and a metal shield protects the power interface. There are no shields to protect the fans at the air outlets. Both Whatsminer M20 and M10 models adopt the same control boards with identical interfaces. New power supply unit P20-12-3350-V1, included with M20s, provides 12V 265A and 12V 12A DC output with a peak power consumption of 3360W.
It uses premium components, demonstrating that the makers paid close attention to every last detail. Its transformer uses the traditional dual voltage mode Whatsminer is famous for, and it is divided into the upper and lower part. With a two-stage low pass, two PFC enable voltage rise, and two LLC cause voltage drop. LLC has higher efficiency for voltage drop with fewer losses.
Power Supply
A programming interface is also used to control voltage. Its two transformers and inductors raise costs, but they also offer a reliable power source. For effective heat emission through suitable ventilation, one of the 12V 1.5A cooling fans is located at the back of the power supply. To prevent oxidation and moisture intrusion, it uses an air exhaustion method. The power supply case is designed for heat dissipation.
It has three hash rate boards with aluminum heat sinks on both sides. There are 26 spring screws on the two heat sinks, and the aluminum heat sink has a high density. The temperature on the side of the miner of 45.3℃ and the cooling fan bearing is 66.5℃.
Noise Level
This device’s noise about one meter away is 75dB, which is pretty standard, as most miners have a noise level of 60-80dB. To better understand this, consider that the noise emission from a vacuum cleaner is 75 dB. Although mining farms are more appropriate, the Whatsminer M20s is used for mining at home because the noise level is ideal. Because there are two fans set up for cooling, the noise is to be expected.

Real Data of MicroBT WhatsMiner M20S
Whatsminer M20S mining machine has two built-in performance modes: normal mode and low power consumption mode. Only the normal mode is supported by this test. The low power consumption mode is not open yet and cannot operate normally. Let’s wait and observe the low power consumption mode calculation data. (Data resource: Jsbit)
Installation and Commissioning
The Whatsminer M20S all-in-one computer is very easy to use once the hardware installation is finished, which involves mounting it in a rack, plugging in the power supply, and connecting an Internet cable.
Open the mining machine’s local management page, change the mining pool address and account name on the mining pool setting page, change the name of the miner (the account set is the account name registered with the mining pool used; this test uses f2pool), and change the operation data. Connect the power meter and run the mining machine with power.
Temperature
The fan started at full speed as soon as the mining machine was turned on. The air inlet temperature was 29.5 degrees, the air outlet temperature was 47.5 degrees, and the current indoor temperature was 27.3 degrees after 24 hours of stable operation (manual sampling).
Noise
The mine’s soundproof door’s measured noise is 65.4 decibels, the test’s close-range noise is 86.7 decibels, and the distance test’s measured noise is 74.5 decibels. picture
