Antminer Z15 family owner hub: Z15 and Z15 Pro

Antminer Z15 family authority hub: Z15 and Z15 Pro are separate Equihash generations, not interchangeable variants. The most important distinction is electrical: legacy Z15 has an external APW7 path and an 11.6–13.0 V DC miner input, while Z15 Pro is an integrated APW12-generation miner with two 200–240 V AC inputs.

Canonical	OEM hashrate	Evidence state	Electrical preflight
Antminer Z15	420 KSol/s	1,510 W ±5%; 3.6 J/KSol ±5%	Miner-side 11.6–13.0 V DC; ten PSU connectors; APW7 compatibility. Verify the exact PSU nameplate for mains requirements.
Antminer Z15 Pro	840 KSol/s ±3%	Power/efficiency conflict: web 2,780 W / 3.31 J/KSol versus manual 2,650 W / 3.15 J/KH	Integrated dual input, 200–240 V AC and 20 A; two 10 A input wires; energize both simultaneously and switch all off to stop.

KSol/s and J/KSol are Equihash-native units. Do not convert these pages into generic cross-algorithm hashrate or efficiency fields, and do not compare their numerics across algorithms. Z15 Pro’s two official performance lanes must remain visibly separate, with no single normalized power or efficiency value in metadata until the exact source conflict is resolved.

Choose exact-model resources

• Z15 official support and Z15 Series specification.
• Z15 Pro official support, current web specification, and official English manual.
• Choose the exact model and revision in Bitmain’s firmware selector. Never cross-flash generations.
• Use Bitmain’s failure diagnostic guide, then organize symptoms and logs or request repair diagnosis.

Before power-up, a qualified person should verify the exact miner and PSU labels, input architecture, circuits, protection, conductors, disconnects, cords, connectors, grounding, ventilation, and applicable requirements. No compatibility, tuning, residential suitability, heat, or economics claim is implied.
