The MicroBT Whatsminer M31s is an SHA-256 algorithm mining device that Micro BT Whatsminer sells. This mining device can mine Bitcoin and has a maximum hash rate of 80th/s with a power consumption of 3220W. The MicroBT Whatsminer M31s is regarded as one of the most profitable miners in the market.

It was released in April 2020 by the Whatsminer company; it comes with a Noise level of 75db. The Noise level indicates that the miner creates noise pollution and would be something to factor in before purchasing. The high power consumption requires a great amount of power supply to be able to consume much power. With such a high hash rate, the level of power supply that will be needed needs to be considered.

For new miners, the electric cost of supplying power to the miner needs to be known and added to the production cost. A high hash rate and high power consumption of any mining device show a high level of power supply needed for the mining to be done. Electric charges vary with location, so locations with high electric costs will affect the product's profitability.

The device comes with 130 x 220 x 390mm and weighs 12500g. It also comes with dual fans that help keep the temperature at the level of optimal performance. The fans help reduce the heat that is emitted from the device when mining. It performs within the temperature range of -5c to -40c. This is the temperature where the performance is optimal. It works over the Ethernet as its interface has a humidity within the range of 5 - 95%.
