WhatsMiner M61

At 202 TH/s and 4000 W, the efficiency works out to approximately ~19.8 J/TH (4000W ÷ 202TH = ~19.8 J/TH) in Normal Mode. Some variant listings suggest ~16.7 J/TH for similar models.

It can be used at home if you have dedicated space, sufficient power and good ventilation—but because of its ~4000 W draw and noise (~75 dB), it’s better suited to a dedicated mining room, garage or small-farm environment rather than a normal living room.

Yes  this model supports an “Overclock Mode” where you can boost the hashrate to ~220 TH/s at ~4800 W. Use caution: higher power draw, increased heat and potential impact on warranty/long-term reliability.

Ensure:

• A reliable PSU and circuit with appropriate current rating

• Proper cabling and breakers

• Good airflow and dust control to maintain uptime

• Firmware updated and monitoring system in place

• Dimensions: ~ 430 × 155 × 226 mm.

• Weight: ~ 13.5 kg (13,500 g) in listings.

• Noise level: Up to ~ 75 dB under load according to spec sheet.
