Evidence-controlled D7 reference: Antminer D7 is an X11 miner associated with DASH in Bitmain’s official algorithm map. Hashrate and efficiency remain in X11-native source units and must not be compared numerically across algorithms.
| Model | Hashrate | Power consumption | OEM efficiency field |
|---|---|---|---|
| D7 | 1,286 GH/s | 3,148 W | 2.4 J/G ±10% |
Efficiency-unit note: Bitmain prints 2.4 J/G ±10%. Direct arithmetic gives 3,148 W ÷ 1,286 GH/s = approximately 2.4479 J/GH, equivalently 2,447.9 J/TH. Those arithmetic equivalents explain the ratio but are not replacement OEM claims. Metadata and structured data must not describe 2,447.9 J/TH as Bitmain’s published efficiency.

Have a qualified person verify the exact D7 and installed PSU labels, both power ports, cords, connectors, circuit capacity, protection, conductors, disconnecting means, grounding, ventilation, and applicable requirements before energizing. Exact mains frequency, maximum current, cord/connector model, PSU submodel, and power-on sequence are not asserted without exact D7 evidence.
