Overview
The Bitmain Antminer E9 Pro, unveiled in February 2023, is Bitmain’s flagship Ethash ASIC miner built for Ethereum and Ethereum Classic mining. Boasting a hashrate of 3.68 GH/s and a power draw of around 2200 W, it delivers about 0.6 J/MH efficiency—optimized for the Ethash algorithm.
Exterior Design
The E9 Pro sports dimensions of 550 × 195.5 × 310 mm (without packaging) and weighs 20.2 kg net (22.0 kg gross). While its form factor resembles other Bitmain S-series miners, it’s optimized specifically for Ethash mining with a sturdy, industrial-grade 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 via dual 10 A AC inputs. The PSU design aligns with Bitmain’s industrial standards, ensuring stable delivery for round-the-clock mining operation.
Cooling System
The E9 Pro uses four high-speed fans arranged for efficient air flow through powerful heatsinks. These fans manage thermal load even under full operation. Noise level is rated at around 75 dB—typical for industrial-class
Fan Specifications
- Model & Size: Martech Industrial-grade fans, 120 × 120 × 38 mm
- Count: 4 fans—two front intake, two rear exhaust
- Voltage & Current: Each runs on 12 V (current not officially disclosed)
- Speed & Airflow: High RPM (exact RPM not published)
- Noise Level: ~75 dB under load
Internal Components
While specific control-board details are not officially disclosed, the E9 Pro features a sturdy internal layout including multiple hashboards, a Bitmain control board with SOC, and firmware supporting industrial-grade reliability.
PSU
Bitmain’s integrated high-load PSU APW121215b features dual power inlets and robust circuitry built for continuous high-power operation .
Control Board
Uses a Bitmain control board with an embedded system-on-chip Ctrl_C9 (SOC), making it firmware-compatible with other Bitmain industrial models.

Profitability (Last Update: 23rd June 2025)
- Hashrate: 3.68 GH/s
- Power Draw: ~2200 W ≈ 2.2 kW
- Daily Energy Use: 2.2 kW × 24 h = 52.8 kWh
- Electricity Cost @ $0.01/kWh: 52.8 kWh × $0.01 = $0.53/day
- Estimated Daily Revenue: ≈ $6.19 (per MiningNow.com)
- Estimated Daily Electricity Cost: ≈ $0.53
- Net Profit: $6.19 – $0.53 = $5.66/day
Conclusion
The Antminer E9 Pro is Bitmain’s top-tier Ethash miner, delivering 3.68 GH/s at ~2200 W with ~0.6 J/MH efficiency. Equipped with BM2280AA ASIC chips, robust hashboards, and a capable cooling system via four industrial fans, it excels in Ethereum-based mining. At low electricity costs, it remains one of the most powerful and profitable Ethash miners available today—ideal for large-scale or industrial mining operations.
