Evidence-controlled Antminer S15 reference: The S15 is a SHA-256 miner with separate normal and low-power operating lanes. Bitmain publishes the low-power values as ranges; the endpoints are not asserted here as paired presets.
| Mode | Hashrate | Power | Efficiency | Frequency |
|---|---|---|---|---|
| Normal | 27 TH/s ±2% | 1,539 W ±7% | 57 J/TH | Auto |
| Low-power published range | 16 TH/s ±2% to 18 TH/s ±2% | 800 W ±7% to 900 W ±7% | 50 J/TH | Auto |
The catalog’s former 28 TH/s / 1,596 W label is not Bitmain’s exact specification. No one-to-one pairing between the low-power range endpoints is implied.

Attached APW8 boundary
The S15 has an attached, all-in-one APW8 power supply and two miner-side PCIe connectors. Bitmain identifies the S15/T15 APW8 by its 16.32–20.04 V output. Other APW8 revisions have different output ranges; an APW8 family name alone does not prove suitability. Confirm the exact PSU label and revision before connection.
Bitmain’s model specification does not publish an exact facility AC voltage, current, frequency, cord, or connector here. A qualified person must verify the PSU nameplate, facility supply, circuit protection, conductors, connector, grounding, and disconnect before energizing the miner.
Firmware, diagnostics, and service
- Select S15 and the exact revision in Bitmain’s firmware selector; do not cross-flash T15 or another model.
- Identify the exact APW8 revision and output range.
- Use Bitmain’s APW8 removal procedure.
- Use the S15/T15 control-board removal procedure.
- Follow Bitmain’s test-jig guidance; it requires the corresponding model master program.
- Review EOS status: S15/T15 reached EOS March 1, 2021; APW8 reached EOS March 31, 2021.
- Organize symptoms and logs; request repair triage; open the family evidence hub.
No architecture, economics, residential-use, heat-use, tuning, compatibility, or parts-interchangeability claim is asserted. Primary source: Bitmain S15 Specifications. Reviewed August 28, 2026.
