Product Overview

The Bitmain Antminer E11 9500M is a high-performance Ethash algorithm ASIC miner designed for Ethereum Classic (ETC) and other Ethash-compatible cryptocurrencies. Delivering 9,500 MH/s (9.5 GH/s) at approximately 2,200W, the E11 9500M is Bitmain’s flagship Ethash miner — bringing their ASIC manufacturing expertise to the ETC mining market with a competitive hashrate and power efficiency profile.

The Antminer E11 series is Bitmain’s dedicated Ethash product line, mirroring their approach in the SHA-256 market with purpose-built ASIC hardware for the Ethash algorithm. At 9,500 MH/s, the E11 9500M sits near the top of the available Ethash ASIC market — delivering substantial ETC mining throughput from a single unit. Since Ethereum’s transition to proof-of-stake in September 2022, Ethereum Classic remains the primary large-cap Ethash proof-of-work coin, making the E11 a focused ETC mining tool.

For South African ETC mining operators, the Antminer E11 9500M offers Bitmain’s proven manufacturing quality and established support infrastructure in the Ethash mining segment. At 2,200W, it sits in the mid-to-high power tier — requiring a dedicated 32A circuit but not the extreme infrastructure demands of the largest SHA-256 miners.

Key Features

• 9,500 MH/s Ethash Hashrate (±5%): Near-flagship Ethereum Classic mining output. At 9.5 GH/s, the E11 9500M delivers substantial ETC pool contribution from a single unit.
• Bitmain ASIC Architecture: Purpose-built Ethash ASIC from the world’s largest ASIC manufacturer. Substantial efficiency advantages over GPU-based ETC mining.
• 2,200W Power Consumption: Mid-to-high power draw for an Ethash miner. Requires a dedicated circuit but below the extreme infrastructure tier of the largest Bitcoin miners.
• Competitive Power Efficiency: Strong Ethash efficiency from Bitmain’s purpose-designed Ethash chip architecture.
• Air-Cooled Industrial Design: High-speed fans managing thermal load in a front-to-back airflow configuration for rack deployment in ventilated mining facilities.

Power & Installation Notes

The Antminer E11 9500M draws approximately 2,200W continuously. South African installations must comply with SANS 10142 and be certified by a registered electrician. A dedicated 20A circuit is the minimum recommended installation — a 32A circuit is preferable to provide headroom. South Africa’s 230V / 50Hz supply is within the unit’s 200–240V input range.

Load shedding at 2,200W is challenging but potentially manageable with a large commercial inverter (5 kVA+) and substantial battery bank. A 5 kVA inverter with a 10 kWh battery provides approximately 4.5 hours of runtime — covering Stage 2–3 outage periods. This is at the upper limit of most home inverter systems; plan for some downtime during major load-shedding stages.

Industrial ventilation is important. The E11 generates significant heat at 2,200W. Active extraction must maintain ambient temperatures below 40°C for sustained operation at rated hashrate.

Electricity Cost Context — South Africa

At R2.80/kWh reference tariff, the estimated monthly electricity cost is:

(2,200 ÷ 1,000) × 24 × 30 × 2.80 = R4,435.20 per month

This is an operating cost estimate only — not a profitability projection. At approximately R4,435/month, the E11 9500M has substantially lower electricity costs than the largest Bitcoin miners — making ETC mining via the E11 more accessible from an operating cost standpoint. Actual tariffs vary by municipality and supply category.

Ideal Use Cases

• Commercial ETC mining operations: The E11 9500M is designed for professional Ethereum Classic mining farms running multiple units with industrial power supply and networking infrastructure.
• Bitmain brand operators expanding into Ethash: Mining operations already running Bitmain Bitcoin (BTC) SHA-256 miners can add ETC Ethash exposure through the E11 9500M with familiar Bitmain platform management tools.
• ETC fleet upgrades: Operators running older Ethash hardware (E9 Pro, GPU-based ETC mining) will find the E11 9500M delivers substantially better hashrate and efficiency per unit.
• Diversified algorithm mining portfolios: Adding Ethash ETC mining alongside SHA-256 Bitcoin or Scrypt LTC/DOGE mining diversifies coin exposure from a single commercial facility.

Frequently Asked Questions

Does the Antminer E11 9500M work on South African power?
Yes. South Africa’s 230V / 50Hz supply is within the unit’s 200–240V input range. A dedicated 20–32A circuit certified by a registered electrician is required.

What coins does the E11 9500M mine?
The E11 mines the Ethash algorithm, primarily targeting Ethereum Classic (ETC). Since Ethereum’s transition to proof-of-stake in 2022, ETC is the primary large-cap Ethash proof-of-work coin. Other Ethash-compatible coins may also be supported.

Which pool should I use for ETC?
Major ETC mining pools include 2Miners, Antpool, ViaBTC, and F2Pool. Configure the pool’s Ethash/ETC stratum URL in the E11’s web interface and enter your ETC wallet address as the worker ID.

How does the E11 compare to the Bombax EZ100 12500M?
The EZ100 12500M delivers 12,500 MH/s at 2,200W vs the E11’s 9,500 MH/s at 2,200W — the EZ100 offers ~32% more hashrate at the same power consumption. The E11 9500M offers the Bitmain brand, firmware ecosystem, and established support infrastructure as differentiating factors.

Can it handle load shedding?
At 2,200W, a 5 kVA inverter with a 10 kWh battery provides approximately 4.5 hours of runtime — potentially covering shorter load-shedding stages. Plan for some downtime during extended outages.
