MicroBT Whatsminer M61 19w 206T

The MicroBT WhatsMiner M61 (206 TH/s, ~19 J/TH) is a next-generation SHA‑256 ASIC miner tailored for Bitcoin and related cryptocurrencies. Launched in December 2024, it delivers a strong hash rate of 206 TH/s while drawing approximately 3,914 W, resulting in a solid energy efficiency of ~19 J/TH . Housed in a compact and rugged metal chassis (430 × 155 × 226 mm), it weighs around 13.5 kg and features dual high-speed fans with an acoustic output of about 75 dB, making it ideal for 24/7 operation in professional mining facilities  Operating reliably within a –5 to 35 °C temperature range and compatible with 220–240 V power via a standard IEC C19 connection, the M61 also includes a built-in PSU and Ethernet interface for easy deployment . For miners with access to competitive electricity rates (e.g., ~$0.045/kWh), this model offers a promising balance of high performance, efficiency, and reliability—making it a compelling option for scalable Bitcoin mining operations.
