Official two-bin reference: Bitmain’s S9k specification covers 13.5 and 14 TH/s versions. Hashrate and power have model-specific tolerances; the manufacturer publishes one efficiency rating for the series.
| Nominal hashrate | Published power | Published efficiency |
|---|---|---|
| 13.5 TH/s ±5% | 1,148 W ±10% | 80 J/TH ±7% |
| 14 TH/s ±5% | 1,190 W ±10% | 80 J/TH ±7% |
Common manufacturer-published details are two 12 V fans rated at 2.4 A and listed at 6,000 rpm, 0–40°C operation, 5–95% non-condensing surrounding humidity, 76 dB at 25°C, ten PCIe power connectors, three hashboards, 180 chips, PCB high-temperature protection at 85°C, and dimensions of 321.3 × 129.6 × 200 mm.
Published weight inconsistency
The manufacturer’s specification table lists a net weight of 5.46 kg and a packing weight of 4.56 kg. Because the packed figure is lower than the net figure, the pair is internally inconsistent. This reference omits a normalized weight instead of silently choosing one. Confirm the exact unit and packed weight directly when shipping, handling, or rack loading depends on it.
Electrical boundary
The manufacturer’s 11.6–13 V value is the miner’s DC input, not a facility AC-input specification. An external PSU supplies the miner. Its exact model and revision govern permissible AC input, circuit loading, cords, connectors, and protection; verify its physical label and manufacturer documentation separately.
Firmware, recovery, and repair
The S9k name does not identify a universal control board or authorize one firmware or recovery image. Record the full unit label, control-board markings, installed firmware version, visible recovery interface, and failure symptom before writing anything. Board identity must match the manufacturer procedure explicitly.
- Identify the exact control board before firmware work.
- After both miner and board match, use the current manufacturer entry and the board-scoped recovery guide.
- For no boot, missing boards, unstable hashing, interrupted writing, overheating, or electrical or physical damage, request Antminer diagnosis.
Unknown or revision-dependent: the specification page does not establish one universal controller, recovery medium, firmware image, external PSU, facility AC requirement, or current retail configuration.
