Overview
The Bitmain Antminer HS3, unveiled in December 2022, is Bitmain’s flagship Handshake (HNS) ASIC miner. Boasting a hashrate of 9 TH/s and power draw of around 2079 W, it delivers about 231 J/TH efficiency
Exterior Design
The HS3 sports dimensions of 430 × 195.5 × 290 mm (without packaging) and weighs 16.1 kg net (17.7 kg gross) While its size resembles small Bitcoin miners, it’s optimized specifically for HNS mining.
Power Supply & PSU Details
It integrates the APW12 power supply (same as on S‑series miners), supporting 200–240 V input at 47–63 Hz and drawing approximately 20 A This rugged PSU ensures stable delivery for prolonged, intense operations.
Cooling System
HS3 employs four high-speed fans, each capable of handling heavy-duty airflow to manage thermal output and maintain optimal performance. Noise level is rated at around 75 dB, typical for industrial-grade ASIC miners
Fan Specifications
- Model & Size: Nidec fans—measuring 120 mm × 120 mm × 38 mm.
- Count: Four fans in total—two at the front, two at the rear.
- Voltage & Current: Each fan runs on 12 V and draws 1.65A
- Speed: Rated at 5,000 RPM for both front and rear fans.
- Airflow: Around 360 CFM, ensuring efficient heat dissipation in high-thermal environments.
- Noise Level: Operates at approximately 75 dB, typical of industrial ASIC miners
Internal Components
While specific control-board details aren’t publicly disclosed, like other Bitmain miners, it features a robust internal layout supporting the PSU and efficient hashboard communication
PSU
- APW121417b PSU—same rugged unit used in several Bitmain ASICs
Control Board
- Uses the Ctrl_C87 control board with an embedded Xilinx Zynq chip—flexible and shared across multiple models including HS3
Hashboards & Hashing Performance
The HS3 includes multiple hashboards delivering a combined 9 TH/s. Efficiency stands at ~231 J/TH—impressive for a Handshake‑algorithm miner Wall‑power draw is officially **2079 ± 10 % W(some sources note ±5 %)
Hashboards & ASIC Chips
- Contains 3× BHB10601 hashboards, each populated with BM2130AA ASIC chips (approximately 92 chips per board)
Operational Specs
- Algorithm: Blake2b+SHA3 (Handshake)
- Voltage: 200–240 V AC
- Operating Temp: 0–40 °C; Storage: –20–70 °C
- Humidity Tolerance: 10–90 % RH
- Network: RJ45 Ethernet 10/100 Mbps
Profitability (Last Update: 19th June 2025)
- Hashrate: 9 TH/s
- Power Draw: ~2079 W ≈ 2.079 kW
- Daily Energy Use: 2.079 kW × 24 h = 49.90 kWh
- Electricity Cost @ $0.01/kWh: 49.90 kWh × $0.01 = $0.50/day
Estimated Daily Revenue: ≈ $4.11 (per MiningNow.com)
Estimated Daily Electricity Cost: ≈ $0.50 ($0.01kWh)
Net Profit: $4.11 – $0.50 = $3.61/day
Conclusion:
The Antminer HS3 is a powerful and efficient HNS miner, delivering 9 TH/s at ~2079 W, built with advanced BM2130AA chips, BHB10601 hashboards, and strong cooling via four Nidec 5000 RPM fans. At low power cost, it can earn up to $4/day, making it profitable in low-cost environments.
As for Handshake (HNS), its mission to decentralize internet naming is unique, but adoption remains niche. If HNS gains traction, the HS3 could offer long-term value. It’s a strong choice for miners betting on decentralized web infrastructure.
