MicroBT Whatsminer M31S+

The refurbished MicroBT Whatsminer M31S+ arrives fully tested and dust-cleaned, delivering ≈ 80 TH/s at about 3.36 kW - roughly 42 J/TH - with the original
Whatsminer firmware.

Each unit includes a P221B/P222B 220–240 V PSU, weighs ~12 kg and measures 430 × 155 × 226 mm. Rated to run from –5 °C to 35 °C, the M31S+ suits home racks, container farms or data-centre overflow.

Note: Not all third-party firmwares such as Braiins OS+ are available to install. It ships and operates with stock MicroBT software.

Electrical reminder: The Whatsminer M31S+ draws about 3.4 kW, which is over the continuous-load limit of a 230 V / 16 A circuit (~3.7 kW). Have a licensed electrician connect the unit - via an IEC C19 cable—to a dedicated CEE socket. Standard household outlets are not intended for this load.
