MicroBT Whatsminer M31s Review

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 70th/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%.

This device comes with a power supply unit(PSU). The supply unit provides an electric voltage of 220v-300v.


Power Consumption of MicroBT Whatsminer M31s

The power consumption of the miner is about 3220W. This is known to be one of the miners with the highest power consumption. This also shows that the miner will have better profitability compared to other devices in the market. The power consumption also means that the hash rate will be high. This then results in higher profitability. But like has been mentioned above, power consumption means that there is a need for a greater power supply, which needs to be considered by any miner that is willing to purchase this product.

The MicroBT Whatsminer M31s run at 200v - 300v that mines at the hash rate of 70th and uses 3220W worth of power.


Noise Level of MicroBT Whatsminer M31s

The Noise level of the device is 70db. This contributes to the fact that the device has a high power consumption with a high hash rate. For new miners, the Noise level should be considered if the setup will be in a residential area. The Noise level is also an indicator the MicroBt Whatsminer M30++ consumes a lot of power and therefore increase the noise it produces.


The profitability of MicroBT Whatsminer M31s

The device mines Bitcoin on its SHA-256 mining algorithm. The profitability of the miner will depend on the price of Bt in the market. It will be crucial that the miner knows that this is estimated profitability gotten from the miner. The miner's profitability per day is $1.41/day, $42.34/month, and $508.08/year. Other factors such as the power supply, temperature, and the hash rate can also affect the device's profitability.


The efficiency of MicroBT Whatsminer M31s

This device's efficiency, which is a result of the power and hash rate it consumes, is at 0.046j/Gh. This is poor compared to the MicroBT Whatsminer M30++ and other similar devices in the market.

Apart from Bitcoin, which the MicroBT Whatsminer M31s mines, the device can also mine these coins: Acoin(ACOIN), Curecoin(CURE), Joulecoin(XJO), Peercoin(PPC), unbreakable(UNB), BitcoinCash(BCH). embark(DEM), Terracoin(TRC), BitcoinSv(BSV).
