Exact OEM reference: Antminer KS5 version KS1-20, sub-model Std, is a kHeavyHash miner. Its manufacturer-supported lane is 20 TH/s. Hashrate and efficiency are scoped only to kHeavyHash.
| Model identity | Algorithm | Typical hashrate | Typical wall power at 25°C | Typical wall efficiency at 25°C |
|---|---|---|---|---|
| KS5 / KS1-20 / Std | kHeavyHash / KAS | 20 TH/s; actual ±3% | 3,000 W; actual ±5% | 150 J/T; actual ±5%, on kHeavyHash |
The OEM’s J/T efficiency is algorithm-specific. It must not be compared numerically with another proof-of-work algorithm.
Single-input electrical and power boundary
| AC input | 220–277 V AC, 47–63 Hz |
|---|---|
| Maximum input current | 20 A |
| Input arrangement | One 20 A input wire |
| Adapted AC output-power requirement | 4,000 W; Bitmain strongly recommends that miner wall power not exceed this value |
| KS5-only PSU roster | APW171215a/c or PW380a/b/c |
| KS5-only cord roster | C20-P13, included |
| Network | RJ45 Ethernet 10/100M |
This is a single-input 220–277 V machine. Do not inherit the KS3’s 200–240 V dual-wire arrangement. Wrong input voltage can damage the server.
This high-power equipment requires a qualified installation. Verify the exact KS5 Std, PSU, inlet and cord labels; supply voltage and frequency; circuit capacity; continuous-load treatment; protection; conductors; connector; disconnecting means; grounding; and applicable requirements before energizing it. The manufacturer roster is scoped only to KS5 and does not establish compatibility with KS5 Pro, another miner, or another PSU or cord revision.
Physical, acoustic, and environmental specification
| Sound | 76 dBA at 25°C with fan at maximum RPM |
|---|---|
| Miner dimensions | 400 × 195 × 290 mm |
| Packaged dimensions | 570 × 316 × 430 mm |

Firmware, support, diagnostics, and repair
- Record the exact KS5 / KS1-20 / Std identity and every installed board, PSU, inlet, connector, and cord label.
- Use Bitmain’s official firmware selector; select the exact KS5 model and installed revision, then read the complete package description.
- Use the official KS5 support hub for the current manual, setup, reset, firmware, troubleshooting, and repair routes.
- For power, zero-hashrate, fan, temperature, firmware, control-board, or hashboard-signal symptoms, start with Bitmain’s ANTMINER failure diagnostic guide.
- Use the ASIC fault finder to organize symptoms and logs.
- Request ASIC repair diagnosis with exact labels, photographs, logs, symptoms, and prior firmware actions.
- Open the Antminer KS5 family hub to keep Std and Pro assumptions separate.
Evidence boundaries: no ASIC identity/count, process, control-board identity, board architecture, tuning range, residential or heat-reuse recommendation, economics, release date, or cross-model firmware, PSU, cord, connector, board, fan, or parts compatibility is asserted. No cross-algorithm comparison is made.
