GMO miner B3 official historical specification
- 33 TH/s maximum-output point
- 3417 W at that point
- Manufacturer rounded label: 103 W/TH; exact derived arithmetic: 103.545 J/TH
- BTC and BCH workload labels; SHA-256
B3 is adjustable, not a fixed 33 TH/s appliance. Automatic mode optimizes hashrate and power up to the maximum based on environment, electricity and network indicators; Manual mode (“Auto Mode Off”) permits user control. The announcement also states a 1950 W / 81 W-per-TH operating point but does not publish its exact paired hashrate. No value is fabricated by division.
B3 planned two PSUs with specifications still to be determined. B2 PSU data is not inherited.
Electrical and physical evidence conflicts
The B2 releases conflict between 100–240 V and 100–250 V tentative PSU ranges and between 2210 W and 2220 W electricity-unit values, while recommending approximately 200 V. Exact delivered voltage, current, plug, connector and 120 V compatibility are not established. B3 PSU specifications were TBD.
Announcement dimensions and weights were planned values: B2 136 × 355 × 163 mm / 4.0 kg; B3 136 × 430 × 163 mm / 5.0 kg. They are retained as evidence notes, not delivered-unit structured facts.
Lifecycle, acoustics and firmware
GMO ended mining-machine development, manufacturing and sales in December 2018. Online monitoring, temperature-response controls and update capability were announced, but no surviving exact firmware binary, version, checksum, controller/board mapping or rollback package is exposed. No numeric acoustic or environmental limits were published.
Current compatibility, MSRP, BTU, profit and home-use conclusions are unavailable.
