Whatsminer M21S 58Th 3428W SHA-256 Second Hand MicroBT Mining Machine Asic Whatsminer
Brief introduction:
Whatsminer M20: Hashrate 45T, power consumption 48W/T, 10A socket
compatible
Whatsminer M21: Hashrate 28T, power consumption 60W/T, 10A socket
compatible
Whatsminer M21B (welfare for old customers): MicroBT provides
hashboard compatible to M3, and users can assembly with M3
components so that the control board, power supply, and casing of
Whatsminer M3 can be reused to cut cost and improve utilization.
Hashrate 28T, power consumption ratio 60W and 10A socket
compatible.
Whatsminer M21S (fast cost recovery): provides standard 56TH hash,
power consumption ratio 60W/T, hash at low power mode 30T, power
consumption ratio 50W, 16A socket is needed.

Product Appearance
The hash board is designed to be compatible with that of Whatsminer M3, so that the user can purchase the hashboard separately to assemble with M3 components and reuse the control board, power supply, casing and other accessories of M3 miner, which can reduce the costs of upgrading and improve the utilization rate.
Fan and Air Circulation
Air inlets are set on the side of the control board and power
interface with a metal shield. The fans at the air outlets do not
have protective shields. Both Whatsminer M20 and M10 models adopt
the same control boards with identical interfaces. M20s comes with
a new power supply unit, P20-12-3350-V1, to provide 12V 265A and
12V 12A DC output with a peak power consumption of 3360W.
It makes use of high-quality materials, which shows the manufacturers paid attention to 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
It also functions with a programming interface to control voltage.
Although its two inductors and transformers cause higher costs,
they provide a stable power supply. One of the 12V 1.5A cooling
fans is at the back of the power supply for successful heat
emission through proper ventilation. To prevent oxidation and
moisture intrusion, it uses an air exhaustion method.
