Evidence-controlled Bitmain Antminer KS7 reference: this page covers Bitmain model KS7, version 10, for kHeavyHash / KAS. It does not describe another manufacturer’s same-name KS7 product.
| Typical hashrate | Power on wall at 25°C | Power efficiency on wall at 25°C |
|---|---|---|
| 40 TH/s ±3% | 3,080 W ±5% | 77 J/T ±5% |
Unit note: the manufacturer datasheet prints efficiency as J/T. The source label is preserved here; in this hashrate context it denotes joules per terahash. The three fields are typical values with the tolerances shown.
Same-name manufacturer boundary
A separate manufacturer publishes a different KAS product with the same KS7 name. It is a distinct product, not an alternate bin or submodel of Bitmain KS7 version 10. No specification, firmware, part, or installation fact may cross between the two identities.
Electrical and network boundary
| AC supply | Single phase |
|---|---|
| Input voltage | 220–277 VAC |
| Input frequency | 50–60 Hz |
| Maximum input current | 20 A |
| Network | RJ45 Ethernet 10/100M |
Manufacturer warning: wrong input voltage may damage the server. Before energizing it, a qualified person must verify the supply, circuit protection, conductors, connector, cord, grounding, and disconnect against the exact machine nameplate and local requirements. The datasheet does not establish a cord, plug, PSU submodel, number of AC inlets, or connector type.
Physical, acoustic, and environmental limits
| Server dimensions | 430 × 195.5 × 290 mm |
|---|---|
| Packaged dimensions | 570 × 316 × 430 mm |
| Net / gross weight | 16.4 kg / 18 kg |
| Noise at 25°C | 75 dBA under the manufacturer’s maximum-fan condition |
| Operating temperature | −20–45°C |
| Storage temperature | −40–70°C |
| Operating humidity | 10–90% RH, non-condensing |
| Operating altitude | ≤2,000 m |
Altitude derating: from 900 m through 2,000 m, reduce the highest operating temperature by 1°C for each 300 m increase in altitude.
Firmware, diagnostics, and evidence provenance
- Select KS7 and the exact revision in Bitmain’s firmware selector; do not cross-flash a same-name or different model.
- Use Bitmain’s official parts picker and verify KS7 plus the exact installed revision; a picker listing does not prove cross-model interchangeability.
- Use Bitmain’s general diagnostic workflow.
- Organize symptoms and logs; request repair triage; open the KS7 service router.
Source provenance: the exact specification is a Bitmain-authored April 2025 KS7 Product Datasheet identifying BITMAIN TECHNOLOGIES INC., model KS7, version 10, and bitmain.com. The currently accessible artifact is hosted by a third-party mirror rather than an official Bitmain attachment URL. The official Bitmain parts picker independently corroborates KS7 identity. Preserve this provenance note until a durable official attachment is available.
No fan count, fan speed, board or chip count, PSU submodel, cord, plug, control-board, architecture, economics, residential-use, heat-use, operating-modification, compatibility, or parts-interchangeability claim is asserted.
