MicroBT WhatsMiner M66S 292T 18.5/TH Bitcoin Mining Machine for Oil Cooling Immersion Equipment

The M66S delivers around 270–298 TH/s for the SHA-256 algorithm, with power consumption approximately 5,000–5,500 W, achieving an energy efficiency of about 18.5 J/TH.

This model supports immersion or oil-cooling (or hydro variants) for thermal management, making it suited for high-density deployment and professional settings.

It mines the SHA-256 algorithm, which supports coins such as Bitcoin (BTC) and other SHA-256-based coins like Bitcoin Cash (BCH).

Probably not in a common residential environment. Its high power draw (5 k+ W), requirement for immersion/hydro cooling infrastructure and high-density setup make it more suited for a dedicated data-centre or mining warehouse. If used at home, you’ll need strong power, cooling, noise & heat management.

You’ll need:

• Three-phase power supply (often 380-480 V) or equivalent capable of ~5-6 kW continuous.

• Immersion or hydro cooling loop (oil or coolant bath, plumbing, heat exchange).

• Adequate ventilation or heat rejection for high heat output.

• Stable network/Ethernet connection.
