| Status | OEM support reference |
Evidence-controlled DR3 reference: Bitmain’s algorithm map associates DR3 with DCR/Decred and HC under the printed algorithm label Blake_256. Do not project DR7’s later algorithm/coin wording onto this model.
| Hashrate | Power | OEM efficiency field | Transparent arithmetic |
|---|---|---|---|
| 7.8 TH/s ±2% | 1,410 W ±7% | 80.73 J/TH ±7% | 1,410 ÷ 7.8 ≈ 180.77 J/TH |
Official-source conflict: the OEM efficiency field and direct power/hashrate arithmetic materially disagree. Both are shown, but neither is selected as a normalized canonical efficiency. Efficiency must be withheld from metadata and structured data.
Electrical and physical boundary
The miner input is 11.6–13 V DC through ten PCIe connectors. Bitmain’s roster supports APW3, APW5, and APW7. This is device-side DC, not a facility-mains specification. A qualified person must verify the exact installed PSU nameplate, mains circuit, protection, conductors, connectors, grounding, and disconnect before energizing.
