About Whatsminer M21S

Like its previous model, Whatsminer M21, Whatsminer M21S comes with an integrated design with a long power supply and smaller sizes. The hash board has a design like that of the Whatsminer m21 to buy the dashboard separately to couple it with M21 components.


The hash rate of the Whatsminer M21S is 56T, which gives it an edge over the M21 model, and the physical size is 155 x 240 x 390mm with a weight of 7.1kg. The size dimension makes the device less bulky to handle and also helps conserve space in mining farms.

The M21s come with a P5-12-2200-V1 power supply to produce an output of DC 12.8V 172A, and the 10A socket in the mining farm works well.
The power supply comes with an aluminum rack, which protects the wires on the connector side. It is used as a handle for ease of usage.
This miner works with a power efficiency of 0.06j/Gh, and it has two 12038 cooling fans, one for blowing air and one for release of air, and the fan power is 12V 2.8A, just like its older model.
