| Efficiency | 96 J/TH ±10% |
| Fans | Seven fans, each listed at 12 V and 2.4 A |
| Noise | 45 dB |
| Hashboards | Four |
| ASIC chips | 216 total |
| PCIe connectors | 13 |
| Operating temperature | 0–40°C |
| Surrounding humidity | 5–95%, non-condensing |
| Dimensions | 360 × 150 × 190 mm |
| Net weight | 5.2 kg |
The manufacturer also lists automatic frequency operation and a chip-temperature value of 80°C. That chip-temperature entry is not an ambient-air target or permission to operate outside the published 0–40°C environmental range.
Electrical boundary
The published 11.6–13 V value is the miner’s DC input. It is not a facility AC-input specification and does not mean the bare miner connects directly to 120 V or 240 V AC. The exact external PSU and its revision determine acceptable facility voltage, circuit loading, cords, connectors, and protection. Confirm the PSU’s physical label and its own manufacturer documentation before energizing the system.
Cooling-system boundary
The specification and owner-support pages establish that this is the S9 Hydro identity, but the model name alone does not define a complete site cooling loop. Do not infer coolant chemistry, flow, pressure, hose, fitting, radiator, pump, or heat-rejection requirements from an air-cooled S9 or from another hydro model. Match the exact unit and the manufacturer’s S9 Hydro operating instructions before filling, connecting, or running the system.
Firmware, recovery, and repair
“S9 Hydro” alone does not identify one universal control-board revision, firmware image, or recovery medium. Record the complete unit label, control-board markings, installed firmware version, visible recovery interface, cooling-system state, and failure symptom before writing firmware or replacing parts. Similar ports and S9-family names are not proof of cross-compatibility.
- Identify the exact control-board revision first.
- Only after the miner and board both match, consult the current manufacturer entry and the board-scoped recovery boundary.
- For no boot, missing hashboards, instability, interrupted writing, leaks, cooling faults, or electrical or physical damage, request Antminer diagnosis.
Unknown or revision-dependent: the specification page does not establish one universal controller, firmware image, recovery medium, external PSU, facility AC requirement, or complete site cooling-loop design.
