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.
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. The power supply case is suitable for heat dissipation.
