Designed by MicroBT, the WhatsMiner M66 276T is one of the most powerful SHA-256 ASIC miners available today. With a maximum hashrate of 276 TH/s and a power draw of ~5492W, it’s ideal for miners who need high output and dependable operation.
Unlike many air-cooled units, the M66 features advanced water cooling, allowing it to run at only 45 dB, making it noticeably quieter than traditional miners. As a result, it’s a great choice for large-scale deployments where thermal efficiency and noise management are essential.
Because it’s built for industrial performance, this miner thrives in controlled environments between 5°C to 45°C, with 5–95% humidity tolerance. Its compact build and Ethernet connectivity ensure it’s both easy to integrate and scalable.
Moreover, it comes brand new from the factory with a 360-day warranty, offering peace of mind from the start. Whether you’re upgrading your farm or expanding into new territories, the M66 276T is a miner you can rely on for serious profitability.
