Performance & Efficiency: Why the A1246 Stands Out
The AvalonMiner 1246 leverages Canaan’s advanced A12 chipset, optimized specifically for the SHA-256 algorithm used by Bitcoin and similar cryptocurrencies. With a maximum hashrate of 90 TH/s, it competes directly with other high-end miners in its class while maintaining relatively low power draw—making it an attractive option for cost-conscious operators.
Energy efficiency is measured in joules per terahash (J/TH), and the A1246 achieves approximately 37.8 J/TH, placing it among the more efficient models available at the time of release. This efficiency translates into lower electricity costs and improved profitability, especially in regions with competitive power rates.
Its dual-fan cooling system ensures consistent thermal performance under continuous load, reducing the risk of throttling or hardware degradation over time. While the noise level of 75 dB is noticeable—typical for industrial-grade miners—it remains manageable in dedicated mining facilities.
Supported Cryptocurrencies
Thanks to its SHA-256 optimization, the AvalonMiner 1246 can mine several major cryptocurrencies, including:
- Bitcoin (BTC) – The flagship cryptocurrency and most profitable SHA-256 coin.
- Bitcoin Cash (BCH) – A fork of Bitcoin with faster transaction processing.
- Bitcoin SV (BSV) – Another Bitcoin derivative focused on scalability.
Miners can choose which blockchain to support based on network difficulty, reward structure, and market value, often switching via pool settings without hardware modifications.
Build Quality & Design
Canaan maintains a reputation for durable, well-engineered mining rigs, and the A1246 is no exception. Its compact yet sturdy frame allows for dense deployment in mining farms, while the modular fan setup enables easy maintenance and replacement.
The unit features an Ethernet interface for stable network connectivity, essential for uninterrupted communication with mining pools. All components are sealed at the factory, ensuring authenticity and protection against tampering.
Mining Profitability Overview
While exact profits depend on variables such as electricity cost, network difficulty, and cryptocurrency prices, the A1246 remains viable under favorable conditions. For example:
- At $0.06/kWh electricity cost and current BTC network difficulty, daily revenue could range between **$7–$10, yielding a potential return on investment within 12–18 months**.
- Using mining calculators, users can estimate payback periods based on real-time data from pools like Slush Pool or F2Pool.
Keep in mind that profitability fluctuates with market dynamics. Sudden drops in BTC price or spikes in global hash rate can impact returns, so ongoing monitoring is crucial.

Frequently Asked Questions (FAQ)
Q: Is the AvalonMiner 1246 still profitable in 2025?
A: Yes, under optimal conditions—such as access to low-cost electricity (< $0.08/kWh) and efficient cooling—the A1246 can remain profitable. However, rising network difficulty means older models may eventually be outpaced by newer, more efficient miners.
Q: Does the AvalonMiner 1246 come with a warranty?
A: New units typically include a 12-month manufacturer warranty covering defects in materials and workmanship. The warranty begins from the production date and does not cover damage from improper use, modifications, or environmental factors.
Q: Can I use the A1246 for home mining?
A: While technically possible, the 75 dB noise level and heat output make it less ideal for residential environments unless placed in a soundproofed or ventilated area. Many users deploy these units in garages, basements, or dedicated mining sheds.
Q: How do I set up the AvalonMiner 1246?
A: Setup involves connecting the miner to a stable power supply (12V DC), linking it to your router via Ethernet, and configuring it through its web interface using the local IP address. You’ll then enter your mining pool credentials to begin hashing.
Q: What power supply do I need?
A: The A1246 requires a compatible 12V DC power supply capable of delivering at least 300A. Most users pair it with APW3++, APW7, or third-party PSU units designed for ASIC miners.
Q: Where can I buy authentic AvalonMiner units?
A: Always purchase from authorized distributors or directly through trusted suppliers who provide proof of authenticity and after-sales support. Beware of counterfeit units sold through unofficial channels.
Final Thoughts: A Solid Choice for Serious Miners
The Canaan AvalonMiner 1246 continues to hold its ground in the competitive ASIC mining landscape. Its combination of high hash rate, solid energy efficiency, and proven reliability makes it a smart choice for both individual enthusiasts and large-scale operations.
While newer models have since emerged with even better specs, the A1246 remains a cost-effective entry point for those seeking dependable SHA-256 mining performance without breaking the bank.
