The ANTMINER E11 is Bitmain's high-output ETC miner for the Etchash algorithm. LeedMiner's catalog records two E11 variants: 9.5 GH/s at 2,470 W and 9.0 GH/s at 2,340 W, both near 260 J/GH. Those numbers make the E11 a serious industrial appliance rather than a quiet home miner. The buying decision depends on the exact batch, current availability, pool-side performance, electricity price and whether the site can support continuous heat and noise.
This review uses current LeedMiner catalog data for the commercial variants and official Bitmain and Ethereum Classic sources for the manufacturer, power-supply and network context. Revenue changes continuously, so no historical daily-income figure should be treated as a promise.
What the ANTMINER E11 mines
The E11 is designed for Ethereum Classic and the Etchash proof-of-work algorithm. Bitmain's corporate history identifies the ANTMINER E11 as an ETC server introduced in its 2025 product cycle. See BITMAIN's official company history for that manufacturer-level confirmation.
Ethereum Classic explains that Etchash is closely related to Ethash and that both GPUs and purpose-built ASICs can participate. The network's official miner FAQ is the best starting point for understanding the algorithm, block rewards and revenue variables. ECIP-1099 documents the technical transition to Etchash and the changed epoch length; consult the official ECIP-1099 specification for protocol details.
Compatibility must be verified against current miner firmware and the intended pool. A statement that a machine supports Ethash does not automatically prove support for every Etchash network or current DAG requirement.
Specifications and efficiency
The LeedMiner catalog currently records:
- E11 9.5 GH/s: 2,470 W, approximately 260 J/GH, 200–240 V and air cooling;
- E11 9.0 GH/s: 2,340 W, approximately 260 J/GH, 200–240 V and air cooling;
- Ethernet networking, approximately 75 dB planning noise and a 14.2 kg chassis;
- operating-temperature planning range of -20°C to 40°C in the catalog.
Treat these as variant-specific planning values. Confirm the nameplate, firmware mode, tolerance and included power supply on the quotation. Similar model names can have different hashrate or power, and a seller image is not enough to identify a batch.
Efficiency is useful for comparison, but facility power matters too. Ventilation fans, networking, transformers and air conditioning add consumption. Measure energy at the site boundary when evaluating a fleet.
Electricity cost for the 9.5 GH/s version
At 2.47 kW, miner-only daily energy is:
2.47 kW × 24 hours = 59.28 kWh per day
At $0.08/kWh, that is approximately $4.74 per day or $142.27 per 30 days. At $0.12/kWh, it becomes about $7.11 per day or $213.41 per 30 days. The 9.0 GH/s version at 2.34 kW uses about 56.16 kWh per day.
These calculations exclude cooling and do not estimate profit. ETC revenue depends on network difficulty, base reward, transaction fees, uncle rate, pool fees, uptime and accepted shares. Use the LeedMiner profit calculator, but replace all defaults with current network and site data.
Power supply and electrical installation
Bitmain's official power-supply compatibility article lists E11 among the models supported by specified APW12-series supplies. Review Bitmain's current PSU selection guide before replacing a power unit. Confirm the exact PSU model, cable specification and input requirements for the delivered E11.
A continuous load above 2.3 kW needs a properly rated circuit, receptacle, cable and overcurrent protection. The catalog's 200–240 V range should be checked against the nameplate and local power system. Have the installation reviewed for continuous operation under local electrical rules. Do not use improvised adapters, overloaded power strips or a circuit shared with unrelated high-load appliances.
Cooling, noise and placement
At roughly 2.5 kW, nearly all electrical input becomes heat in the room. The E11's air-cooled chassis must receive clean, cool intake air and a direct exhaust route. Recirculation raises fan speed, noise and component temperature.
The catalog's approximately 75 dB value places this machine in industrial-noise territory. Actual sound depends on fan speed, temperature, distance and room surfaces, but the E11 should not be presented as a bedroom appliance. Plan hearing protection and workplace exposure controls where required, and isolate occupied areas from exhaust and fan noise.
Dust management matters as well. Use appropriate filtration at the room level without starving the miner's airflow. Record inlet temperature, board temperature, fan RPM and rejected-share rate so a deteriorating condition can be detected before shutdown.
Commissioning checklist
- Verify the serial number, variant, included PSU and shipping condition.
- Confirm the circuit, voltage, plug and grounding before energizing.
- Keep intake and exhaust paths unobstructed and separated.
- Find the miner's local IP address and change default credentials.
- Use official firmware and verify its checksum or release source.
- Configure primary and backup Etchash pool endpoints.
- Allow the machine to stabilize, then compare dashboard and pool-side hashrate.
- Measure wall power, inlet temperature, fan speed and rejected shares.
- Keep a baseline for the first 24–72 hours and review it after every firmware or room change.
Bitmain's Miner Status Page guide explains common real-time and average hashrate fields. Pool-side accepted hashrate remains the better evidence of delivered work.
Availability and current alternatives
The two ANTMINER E11 listings were published but out of stock when checked on August 8, 2026. That means this review should not imply immediate shipment. Request an availability check, and compare current in-stock Etchash machines rather than substituting an unknown E11 batch.

Verdict
The ANTMINER E11 is a high-throughput ETC platform whose 9.5 GH/s configuration can reduce the number of units needed for a target hashrate. Its trade-offs are industrial power, heat, noise and an economic case that changes with ETC network conditions. Availability is also decisive: a published product page is not proof of current stock.
Use the ASIC comparison tool to place E11 planning values beside current Etchash alternatives. Then contact LeedMiner with your destination, voltage, all-in electricity rate, ventilation capacity and target hashrate. Ask for an Inquiry quotation when a live listing has no price, and require exact batch, warranty and delivery evidence before payment.
