Antminer KS5 family owner hub: Standard and Pro

Antminer KS5 family identification: KS5 Std and KS5 Pro share model/version labels but are distinct sub-models with different exact performance lanes. Confirm Std or Pro on the complete identity before selecting specifications, firmware, electrical assumptions, or repair parts.

Canonical sub-model	Exact kHeavyHash lane	Electrical class	Reference
KS5 / KS1-20 / Std	20 TH/s; 3,000 W; 150 J/T, typical at 25°C	One 20 A input; 220–277 V AC; 4,000 W adapted-power requirement	Antminer KS5
KS5 / KS1-20 / Pro	21 TH/s; 3,150 W; 150 J/T, typical at 25°C	One 20 A input; 220–277 V AC; 4,000 W adapted-power requirement	Antminer KS5 Pro

For each sub-model, actual hashrate fluctuates ±3%; actual wall power and efficiency fluctuate ±5%. J/T is explicitly scoped to kHeavyHash. Do not compare or calculate efficiency deltas across algorithms.

Electrical preflight

1. Photograph the complete model/version/sub-model, installed board, PSU, inlet, connector, and cord labels.
2. Confirm one 20 A input at 220–277 V AC and 47–63 Hz. Wrong voltage can damage the server.
3. Respect the 4,000 W adapted AC output-power requirement; Bitmain strongly recommends that miner wall power not exceed it.
4. Have a qualified person verify circuit capacity, continuous-load treatment, protection, conductors, connectors, cords, disconnecting means, grounding, and local requirements.
5. The current manufacturer roster lists APW171215a/c or PW380a/b/c and an included C20-P13 cord for KS5 only. It does not name KS5 Pro. Do not extend that roster to Pro.

Do not inherit KS3 or unrelated hardware assumptions

KS3 uses a different published electrical boundary. Do not transfer its 200–240 V, dual-wire, efficiency-label conflict, firmware, PSU, cord, board, fan, or parts assumptions to KS5 or KS5 Pro. Likewise, similarly named miners from another manufacturer are outside this family and establish no compatibility or specification.

Firmware, support, diagnostics, and repair

• Select firmware by exact KS5 Std or KS5 Pro identity and installed revision.
• Use Bitmain’s KS5 support hub for exact Std manual and operating routes; do not extend a Std-only procedure to Pro unless explicitly matched.
• Start with Bitmain’s failure diagnostic guide for power, zero-hashrate, fan, temperature, firmware, control-board, and hashboard-signal symptoms.
• Use the ASIC fault finder to organize symptoms and logs.
• Request ASIC repair diagnosis with exact identity and component labels, photographs, logs, symptoms, and prior firmware actions.

Family boundaries: this hub does not merge KS5 Std and Pro, absorb KS3 or unrelated manufacturer records, assert component interchangeability, or compare kHeavyHash performance with another algorithm. No unsupported silicon, controller, tuning, home, heat, economics, lifecycle, or release claims are made.

Primary evidence: Bitmain’s official KS5 and KS5 Pro specifications, current KS5-only PSU/cord roster, firmware selector, KS5 support hub, and diagnostic guide linked from the two canonical references. Reviewed August 28, 2026.
