Overview
The Bitmain Antminer D9, unveiled in February 2023, is Bitmain’s flagship X11 ASIC miner built for Dash mining. Boasting a hashrate of 1.77 TH/s and a power draw of around 2839 W, it delivers about 1.60 J/GH efficiency—optimized for the X11 algorithm.
Exterior Design
The D9 sports dimensions of 430 × 195.5 × 290 mm (without packaging) and weighs 16.1 kg net (17.7 kg gross). While its size resembles other Bitmain S-series miners, it’s optimized specifically for X11 mining with a solid and compact frame.
Power Supply & PSU Details
It integrates a rugged power supply supporting 200–240 V input at 47–63 Hz and draws approximately 20 A in total. The PSU design is similar to the APW12 used in previous Antminer models and ensures stable delivery for continuous high-performance operation.
Cooling System
The D9 employs four high-speed fans, each designed to handle demanding thermal loads. These fans maintain safe operating temperatures even under full load, critical for maintaining long-term stability and efficiency. Noise level is rated at around 75 dB, typical for industrial-grade ASIC miners.
Fan Specifications
- Model & Size: High-efficiency Nidec fans—120 mm × 120 mm × 38 mm
- Count: 4 fans total—two front intake, two rear exhaust
- Voltage & Current: Each fan operates at 12 V and draws ~1.65 A
- Speed: Rated at ~5,000 RPM for both front and rear fans
- Airflow: Roughly 360 CFM, optimized for dense ASIC layouts
- Noise Level: Operates at approximately 75 dB—standard for this class of equipment
Internal Components
While specific control-board details aren’t officially disclosed, the D9—like other Bitmain units—features a robust internal configuration with three hashboards and a standardized control board setup that supports reliable performance and firmware upgrades.
PSU
Bitmain’s integrated high-load PSU (similar to APW121417B) supports sustained power delivery with dual power inlets and high-efficiency internal circuitry designed for 24/7 industrial operation.
Control Board
Uses a Bitmain control board with an embedded system-on-chip (SOC), likely based on the Xilinx Zynq family. This provides flexibility and compatibility with other high-end Bitmain models including the D9.
Hashboards & Hashing Performance
The D9 includes 3 hashboards delivering a combined 1.77 TH/s. Efficiency stands at ~1.60 J/GH—outstanding for an X11-algorithm miner. Wall power draw is officially rated at 2839 ± 10 % W, depending on the environment and firmware version.
Hashboards & ASIC Chips
Contains 3× hashboards populated with BM1766 ASIC chips (approximately 126 chips per board), engineered for high-performance X11 hashing with optimal thermal efficiency.
Operational Specs
- Algorithm: X11 (used primarily for Dash and related coins)
- 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: 23rd June 2025)
- Hashrate: 1.77 TH/s
- Power Draw: ~2839 W ≈ 2.839 kW
- Daily Energy Use: 2.839 kW × 24 h = 68.14 kWh
- Electricity Cost @ $0.01/kWh: 68.14 kWh × $0.01 = $0.68/day
- Estimated Daily Revenue: ≈ $3.75 (per MiningNow.com)
- Estimated Daily Electricity Cost: ≈ $0.68 ($0.01/kWh)
- Net Profit: $3.75 – $0.68 = $3.07/day
Conclusion
The Antminer D9 is a powerful and efficient X11 miner, delivering 1.77 TH/s at ~2839 W, built with BM1766 chips, three high-performance hashboards, and a strong cooling system with four 5,000 RPM fans. At low electricity rates, it can still earn a modest daily profit, making it a reasonable option in regions with low energy costs.
As for Dash and other X11-based cryptocurrencies, the long-term viability depends on adoption and coin value. If X11 coins maintain or gain value, the D9 remains a viable option for enthusiasts and professional miners alike betting on the future of privacy and instant-payment digital assets.
