Official two-bin reference: Bitmain’s S9j specification covers 14 and 14.5 TH/s versions. Hashrate is rated ±5%; paired power and efficiency are rated ±10%.
| Nominal hashrate | Published power | Published efficiency |
|---|---|---|
| 14 TH/s ±5% | 1,320 W ±10% | 94 J/TH ±10% |
| 14.5 TH/s ±5% | 1,350 W ±10% | 93 J/TH ±10% |
Common manufacturer-published details are two 12 V fans rated at 2.4 A, both listed at 6,000 rpm, 0–40°C operation, 5–95% non-condensing surrounding humidity, 76 dB noise, ten PCIe power connectors, three hashboards, 189 chips, 4.2 kg net weight, and dimensions of 350 × 135 × 158 mm.
Electrical boundary
The published 11.6–13 V figure is the miner’s DC input. It is not a 120 V or 240 V facility AC rating. The exact external PSU governs acceptable AC input, circuit loading, cord, connector, and protection requirements; verify the PSU model and revision independently.
Firmware and recovery
Do not choose firmware, recovery media, a control board, or a replacement hashboard from “S9j” alone. Record the full miner label, control-board markings, installed firmware version, visible recovery interface, and symptom. Board identity must match the image or procedure explicitly.
- Identify the exact control board before changing firmware.
- Once miner and board identity both match, consult the current manufacturer entry and the board-scoped recovery guide.
- For no boot, missing boards, unstable operation, interrupted writing, or electrical or physical damage, request Antminer diagnosis.
Unknown or revision-dependent: the specification page does not establish one universal control-board revision, firmware image, recovery medium, external PSU, facility AC requirement, or current sold configuration.
