WhatsMiner M21S 38-58TH/s, 2128-3360W, 54-60J/TH Fully Functional withPSU Used

Size: 155 x 240 x 390mm. Power: 2128 - 3360W 240v PSU. Temperature: 5 - 45 °C. Humidity: 5 - 95 %. The WhatsMiner M21S is a powerhouse in the realm of Bitcoin mining, with profitability that remains steady even after halving events.

Its resilience extends beyond market fluctuations, as it is remarkably resistant to environmental factors. Its robust design allows it to withstand dry, wet, and dirty conditions without malfunction, making it a standout performer among ASICs and a reliable choice for miners. The machine requires only a wired internet connection and a power source to begin mining.

Variations exist in fan connectors (4 or 6 pin), hashboard, and control board models, but these differences do not affect performance. It's power demands are strict, requiring a steady supply of 220v to 240v to function correctly. Any deviation from this voltage may cause operational issues, there is low risk for damage if voltage falls outside this range temporarily. Adherence to specific electrical requirements ensures optimal functionality and longevity. With its efficient design and unwavering performance, the WhatsMiner M21S remains a top choice for those entering the dynamic landscape of cryptocurrency mining.

Just connect it to the internet and power, and you're ready to go. Bulk discounts are available for orders of 10 or more machines. We keep a stock of excess parts for all WhatsMiner M21S models to address any issues that may arise during deployment.

Upon receiving your machines, carefully unbox them and place them in a well-ventilated area with adequate filtration. Ensure that both power and internet are connected. To configure your mining pool, please consult this tutorial.

Regularly use an air compressor to clean dust from the machine, filters, and fans to maintain optimal heat dissipation and longevity. Verify that your electrical panel delivers 200-277v, as many North American buildings default to 120v panels. Soundproofing and HVAC ducting may be needed depending on the location of operation. Do NOT update or change the firmware! We have tested optimal firmware versions to ensure nameplate hashrate and machine longevity.

Firmware changes are made at your own risk, and versions are tracked. Non-functionality is the only valid reason for parts or machine replacement.

If you receive a malfunctioning unit, we will replace parts or the unit at no additional cost. Note that machines may arrive with cosmetic imperfections such as rust, scratches, or corrosion, which do not affect performance and are not valid reasons for return.
