Official multi-bin reference: Bitmain documents the Antminer S19j as model 240-Cb in 82, 86, 90, and 94 TH/s bins. The corresponding wall-power ratings at 25°C are 2,829, 2,967, 3,105, and 3,243 W; all four bins are rated at 34.5 J/TH.
| Nominal bin | Wall power at 25°C | Efficiency |
|---|---|---|
| 82 TH/s | 2,829 W | 34.5 J/TH |
| 86 TH/s | 2,967 W | 34.5 J/TH |
| 90 TH/s | 3,105 W | 34.5 J/TH |
| 94 TH/s | 3,243 W | 34.5 J/TH |
Bitmain prints +3% beside nominal hashrate rather than a symmetric tolerance. Power and efficiency are ±5%. These are rated bins, not a continuous tuning range.
Electrical, physical, and environmental requirements
The official input is 200–240 V AC, 47–63 Hz and 20 A maximum-condition total through two 10 A inputs. Network access is RJ45 Ethernet 10/100M. The server including PSU is 400 × 195.5 × 290 mm and 14.6 kg net.
The manufacturer documents 0–40°C operation, −20–70°C storage, 10–90% non-condensing RH, and altitude up to 2,000 m. Its specification and setup pages disagree slightly on gross packaged weight and the altitude where temperature derating starts, so this reference does not collapse those revision differences into one asserted value.
Exact-name boundary
S19j, S19j Pro, S19j Pro+, and S19j XP are separate identities. Matching 240-Cb text, chassis appearance, or an “S19j” prefix does not establish the same bin, PSU, controller, hashboard, firmware, or recovery route.
Firmware and recovery
Bitmain’s grouped factory-firmware procedure has separate BB and AML routes for this model group. That proves board-specific handling, not that every S19j uses one controller or that packages are interchangeable.
- Identify the exact board and installed version before selecting any file.
- Secure Boot enabled and Root Authority disabled do not establish an unlock or recovery method.
- For no boot, package mismatch, interrupted writing, instability, or electrical and thermal symptoms, request Antminer diagnosis.
