The Ethereum ASIC Miner A11 is a high-performance mining device built for the Ethash algorithm, originally used by the Ethereum network. Manufactured by leading ASIC producers such as Innosilicon, the A11 series delivers hash rates ranging from 1,500 MH/s to 2,200 MH/s depending on the specific model, with power consumption typically between 2,100 W and 2,800 W. This makes the A11 significantly more efficient than GPU-based mining rigs for Ethash-based cryptocurrencies.
Models and Variants
The A11 series includes several variants that differ in hashrate and efficiency. Common models include the A11 Pro 2000 (2,000 MH/s ±10% at around 2,500 W), the A11 1500 (1,500 MH/s at about 2,100 W), and the A11 2200 (2,200 MH/s at roughly 2,800 W). Each model retains the same core design and is compatible with Ethash-based coins. When choosing a unit, buyers should consider local electricity rates and cooling capacity, as higher power draw models deliver proportionally more hashrate.
Key Specifications
While exact specifications vary by model, the typical A11 miner offers:
- Hash Rate: approximately 2,000 MH/s (±10%)
- Power Consumption: around 2,500 W
- Algorithm: Ethash (compatible with Ethereum, Ethereum Classic, and other Ethash coins)
- Cooling: Air-cooled with dual 120 mm fans
- Noise Level: ~75 dB
- Weight: approximately 12 kg
Mining After The Merge
With Ethereum’s transition to Proof of Stake (the Merge) in September 2022, direct ETH mining became obsolete. However, the A11 remains relevant for mining other Ethash-based cryptocurrencies. The most popular alternative is Ethereum Classic (ETC), where the A11’s hashrate and efficiency remain competitive. Other Ethash coins that can be mined include Callisto (CLO), Expanse (EXP), and QuarkChain (QKC). Many mining pools now support these coins, and mining software like lolMiner, TeamRedMiner, and NBminer remain compatible. Before switching coins, miners should verify current network difficulty and profitability using online calculators.
Setting Up an A11
Setting up an A11 miner requires a few key components: a stable power source (220–240 V circuit strongly recommended), wired Ethernet connection, and adequate ventilation. The miner comes with a built-in power supply, so no external PSU is needed. After connecting power and network, users configure the IP address through their router and point the miner to an Ethash-compatible pool with their wallet address. Many pools offer simple setup guides. The A11 typically runs best with firmware provided by the manufacturer or third-party alternatives that offer tuning options for reducing power draw.
Considerations for Buyers
When evaluating an Ethereum ASIC Miner A11, important factors include electricity cost, cooling capacity, noise regulations, and upfront investment. The A11’s noise output (~75 dB) requires proper soundproofing or remote placement for residential use. In the post-Merge market, used A11 prices have adjusted, making them more accessible for hobbyists. Always research current network difficulty and profitability calculators before purchasing used mining hardware. Additionally, consider the unit’s condition – hour count, fan wear, and whether it has been overclocked or run in a clean environment.
Frequently Asked Questions
Can I still use the A11 after the Ethereum Merge?
Yes, the A11 can be repurposed to mine other Ethash-based cryptocurrencies, most notably Ethereum Classic (ETC). Many miners continue to operate A11 units profitably on ETC and similar coins.
How loud is the A11?
The A11 generates about 75 dB of noise at full operation – similar to a vacuum cleaner. This requires a dedicated space with sound dampening if used near living areas.
Does the A11 require special electrical setup?
Yes. With power consumption around 2,500 W, the A11 typically needs a dedicated 220–240 V circuit. Standard 120 V household outlets may not supply enough power continuously. Consulting an electrician is recommended.
Where can I find mining software for the A11?
Most Ethash mining software such as lolMiner, TeamRedMiner, and NBminer support the A11. Always download from official sources to avoid malware.
