GMO miner B2 official historical specification
- 24 TH/s
- 1950 W at that point
- Manufacturer rounded label: 81 W/TH; exact derived arithmetic: 81.25 J/TH
- BTC and BCH workload labels; SHA-256
B2 was announced at a fixed 24 TH/s / 1950 W performance point with one included PSU and daisy-chain support up to 32 units.
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.
