Specifications
Out of all the M20 series, this model has the highest hash rate.
The power consumption ratio is 48W/T. With a power consumption of
3200W, it is a bit on the high side, which reduces profitability.
It uses the SHA-256 algorithm to work and can mine around 40 coins.
But the most profitable coins are Bitcoin(BTC) and Bitcoin
Cash(BCH).
It is equipped with one 16A 3×1.5mm power cord (Note: the power
plug is specifically for 16A jack, the miner power plug is also
only for 16A power cord interface) and adopts a classic single tube
design. It has a size of 390x158x240mm and a weight of 11.4kg.
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. The power
supply case is suitable for heat dissipation.
It has three hash rate boards with aluminum heat sinks on both
sides. The aluminum heat sink has a high density, and the two heat
sinks have 26 spring screws. The temperature on the side of the
miner of 45.3℃ and the cooling fan bearing is 66.5℃.

They started their flagship Whatsminer, a Plug and Play Bitcoin
Mining Hardware equipment, allowing end-users to start mining coins
on the SHA-256 algorithm immediately and join the digital currency
gold rush. What made this popular was the ease of usage for even
first time miners.
