Evidence-limited Antminer K5 reference: Bitmain’s maintained records identify K5 as an Eaglesong miner associated with CKB (Nervos). An exact manufacturer performance specification was not located in the current durable support corpus, so this page publishes no hashrate, power-consumption, efficiency, or physical matrix.

The electrical facts above describe the miner-side DC boundary and a manufacturer family roster. They do not establish the AC input rating of an individual PSU revision. Facility voltage, phase, current, frequency, cord, connector, circuit protection, and grounding remain unresolved. A qualified person must inspect the exact PSU nameplate and revision and verify the complete installation before energizing it.
Hashrate, wall power, efficiency, dimensions, weight, board and chip counts, noise, ambient operating range, humidity, and frequency remain unpublished here pending an exact K5 primary source. No ProductModel specification is asserted.
Firmware, diagnostics, and service
- Open Bitmain’s firmware selector and select K5 only if the exact model and revision are present; do not cross-flash another model.
- Follow Bitmain’s firmware-download workflow.
- Use Bitmain’s general diagnostic workflow.
- Organize symptoms and logs; request repair triage; open the K5 service router.
End of service: Bitmain’s current consolidated roster dates K5 to March 1, 2021. This page does not imply continuing manufacturer repair coverage.
No architecture, economics, residential-use, heat-use, operating-modification, compatibility, or parts-interchangeability claim is asserted. Evidence anchors: Bitmain algorithm map, PSU roster, and fan roster. Reviewed August 28, 2026.
