AvalonMiner 1246

What Is AvalonMiner 1246?

AvalonMiner 1246 is a Bitcoin mining ASIC machine made by Canaan for SHA-256 proof-of-work mining.

It is designed to perform a very specific job: calculate massive numbers of SHA-256 hashes in order to compete for mining rewards on proof-of-work blockchains that use the same hashing algorithm as Bitcoin.

The official Canaan Avalon Miner A1246-90T product page lists the 90T version with a hashrate of 90 TH/s, power consumption of 3420W, and power efficiency of 38 J/TH.

In simple terms, AvalonMiner 1246 is not a coin, token, wallet, exchange account, or mining pool.

It is physical mining hardware that turns electricity into computational work for Bitcoin-style mining.

The machine belongs to the AvalonMiner product family, which is one of the long-running ASIC miner lines in the Bitcoin mining industry.

For a crypto glossary, AvalonMiner 1246 is important because it helps users understand how Bitcoin mining depends on specialized chips, energy efficiency, cooling, network difficulty, and miner economics.

How AvalonMiner 1246 Works

AvalonMiner 1246 works by repeatedly hashing block header data until it finds a result that meets the network’s difficulty target.

The Bitcoin developer reference explains that a Bitcoin block header includes fields such as the previous block hash, Merkle root, time, nBits target, and nonce, and miners change values like the nonce to search for a valid hash below the target threshold through Bitcoin block header proof-of-work.

This process is called proof of work because the miner must perform real computation before the network accepts the result.

The AvalonMiner 1246 does not understand market news, price charts, or trading signals.

It simply runs specialized ASIC chips that are optimized for SHA-256 hashing.

SHA-256 is part of the SHA-2 family of secure hash algorithms described by the NIST Secure Hash Standard.

When the machine is connected to a mining pool, it usually receives mining jobs from the pool server and submits valid shares that prove it is contributing hashrate.

If the pool finds a valid block, the miner receives a share of the pool reward based on the pool’s payout rules and the miner’s contribution.

Most individual AvalonMiner 1246 owners use pools because solo mining with one 90 TH/s machine is statistically unlikely to find a Bitcoin block within a predictable time frame.

Key AvalonMiner 1246 Specifications

The most commonly referenced AvalonMiner 1246 model is the A1246-90T version.

Its headline hashrate is 90 TH/s, which means it can perform about 90 trillion SHA-256 hash attempts per second under normal operating conditions.

Its listed wall power consumption is 3420W, which means it can use 3.42 kilowatts when running near rated performance.

Its listed efficiency is 38 J/TH, which means it uses about 38 joules of energy for each terahash of hashing work.

The Canaan specification also lists air cooling with four 12038 fans, an input voltage range of 185V to 285V AC, an operating temperature range of -5°C to 35°C, a maximum noise level of 75 dB, net dimensions of 331mm by 195mm by 292mm, and a net weight of 12.8 kg.

These specifications matter because Bitcoin mining profitability is heavily affected by electricity cost, machine efficiency, uptime, cooling quality, and network difficulty.

A 90 TH/s machine can still perform real Bitcoin mining work, but its economics in 2026 depend strongly on whether the operator has access to low-cost power and good heat management.

For current revenue estimates, miners often compare machine settings against a dynamic AvalonMiner 1246 profitability calculator, but calculators should be treated as estimates because Bitcoin price, network difficulty, transaction fees, and pool payouts change constantly.

Why Hashrate Matters for AvalonMiner 1246

Hashrate is the speed at which a miner performs hash calculations.

For AvalonMiner 1246, 90 TH/s means the machine is attempting 90 trillion hashes every second.

A higher hashrate gives a miner a larger share of the total network or pool hashrate.

That larger share can increase expected mining rewards, but it does not guarantee profit.

Mining rewards are probabilistic because proof-of-work mining is a competition to find a valid hash before other miners do.

When mining through a pool, the pool smooths this randomness by combining the work of many miners and distributing rewards according to contribution.

For a single AvalonMiner 1246, pool mining is usually more practical than solo mining because the miner’s share of global Bitcoin hashrate is extremely small.

Hashrate should always be evaluated together with electricity use because a powerful miner can still lose money if power costs are too high.

This is why energy efficiency is often more important than raw hashrate when comparing mining machines.

Why Power Consumption Matters

Power consumption is one of the most important numbers for AvalonMiner 1246 because electricity is usually the largest operating cost in Bitcoin mining.

At 3420W, one AvalonMiner 1246 running continuously uses about 82.08 kWh per day before considering extra cooling or facility losses.

This estimate comes from multiplying 3.42 kW by 24 hours.

If electricity costs $0.05 per kWh, the miner’s base electricity cost would be about $4.10 per day.

If electricity costs $0.10 per kWh, the base electricity cost would be about $8.21 per day.

If electricity costs $0.15 per kWh, the base electricity cost would be about $12.31 per day.

These figures show why the same AvalonMiner 1246 can be profitable in one location and unprofitable in another.

They also show why mining operators care about power contracts, heat reuse, ventilation, uptime, and infrastructure design.

A miner should calculate electricity cost before buying hardware because a low purchase price can still lead to negative cash flow if energy is expensive.

Energy Efficiency and 38 J/TH

Energy efficiency tells miners how much electricity is needed to produce a unit of hashrate.

The official 38 J/TH rating means AvalonMiner 1246 was a serious industrial miner in its generation, but it is less efficient than newer high-end ASIC machines available in the current market.

This does not make the AvalonMiner 1246 useless.

It means the machine is more sensitive to power price than newer, more efficient hardware.

An operator with very low-cost electricity may still consider older miners useful, especially if the purchase price is low and the hardware is already available.

An operator with expensive residential electricity may find that the miner produces more electricity cost than mining revenue.

Efficiency also affects heat output because nearly all electricity used by an ASIC miner becomes heat.

A 3420W machine behaves like a strong electric heater, so cooling is not optional.

Good mining planning treats electricity, heat, airflow, noise, and safety as one connected system.

Cooling, Noise, and Operating Conditions

AvalonMiner 1246 uses air cooling and four high-speed fans to move heat away from the hashboards and internal power supply.

The official specification lists a maximum noise level of 75 dB, which is loud enough to be uncomfortable in a normal living space.

This makes the machine more suitable for garages, workshops, dedicated mining rooms, data centers, or industrial spaces than bedrooms or offices.

Airflow matters because hot air trapped around the miner can reduce stability and may shorten hardware life.

Dust also matters because dust buildup can block airflow and force fans to work harder.

Operators usually need intake air, exhaust air, dust control, safe wiring, and regular inspection.

The listed operating temperature range of -5°C to 35°C does not mean every environment inside that range is equally safe or efficient.

Stable temperatures, clean airflow, and correct voltage are better for long-term operation than running near the edge of the machine’s limits.

Because the machine runs at high wattage, users should avoid weak extension cords, overloaded circuits, and unsafe power adapters.

AvalonMiner 1246 and Bitcoin Mining Profitability

AvalonMiner 1246 profitability depends on Bitcoin price, network difficulty, transaction fees, pool payout method, uptime, hardware cost, repair cost, and electricity price.

Bitcoin mining revenue is not fixed because the network automatically adjusts mining difficulty as total hashrate changes.

When more global hashrate joins the network, each miner’s expected share of new rewards can decline unless the miner also adds more hashrate.

Bitcoin rewards also include a block subsidy and transaction fees, and the Bitcoin developer documentation on block rewards explains that the coinbase transaction collects the available block reward.

After the 2024 Bitcoin halving, the block subsidy became 3.125 BTC per block, and dynamic trackers such as BitInfoCharts Bitcoin network statistics show current block reward, difficulty, block time, and network data.

This matters for AvalonMiner 1246 because lower block subsidies make efficient operation more important.

Transaction fees can add extra revenue, but fees vary from block to block and cannot be counted on as a stable replacement for inefficient hardware.

A miner should model best-case, base-case, and worst-case scenarios before running the machine at scale.

How to Calculate AvalonMiner 1246 Electricity Cost

The basic electricity formula is power in kilowatts multiplied by hours used multiplied by the electricity price per kWh.

For AvalonMiner 1246, 3420W equals 3.42 kW.

If the miner runs for 24 hours, it uses about 82.08 kWh per day.

If the miner runs for 30 days, it uses about 2462.4 kWh per month.

At $0.05 per kWh, monthly electricity cost is about $123.12.

At $0.10 per kWh, monthly electricity cost is about $246.24.

At $0.15 per kWh, monthly electricity cost is about $369.36.

These numbers do not include extra fans, air conditioning, transformers, networking equipment, downtime, pool fees, maintenance, or facility costs.

A serious mining calculation should include all costs, not only the miner’s rated wall power.

This is especially important for older ASICs because small changes in electricity price can change the result from profitable to unprofitable.

Setup Basics for AvalonMiner 1246

AvalonMiner 1246 setup usually involves placing the machine in a ventilated area, connecting suitable power, connecting Ethernet, locating the miner on the local network, and entering mining pool settings in the miner dashboard.

The machine is not normally operated through Wi-Fi because mining ASICs usually rely on wired Ethernet for stable communication.

Stable network access matters because rejected shares and downtime reduce expected rewards.

A user should confirm the correct voltage range before powering the machine because the A1246 is designed for high-voltage AC input.

A user should also confirm that the electrical circuit can handle the load safely and continuously.

Mining hardware should be treated like industrial equipment rather than a normal consumer computer.

The dashboard normally allows users to configure pool URLs, worker names, passwords, network settings, firmware options, and monitoring information.

After setup, the user should monitor hashrate, chip temperature, fan speed, rejected share rate, error logs, and uptime.

Consistent monitoring helps detect airflow problems, unstable power, bad network connections, or aging hardware.

Maintenance and Common Issues

AvalonMiner 1246 maintenance focuses on airflow, dust control, temperature, fan health, firmware stability, and power quality.

Dust can collect on fans, grills, and hashboards, which may raise temperatures and reduce performance.

Fans can wear out because ASIC miners often run continuously at high speed.

Power supplies can become stressed by heat, poor voltage, or unstable electrical infrastructure.

Hashboards may show errors if chips overheat, if connectors become loose, or if the machine has been exposed to moisture or poor handling.

Operators should shut down equipment safely before cleaning or inspection.

They should avoid opening power components unless they have proper electrical training because high-wattage mining equipment can be dangerous.

For warranty or repair questions, users can check official support resources such as Canaan’s Avalon product warranty check guide.

Used AvalonMiner 1246 units should be inspected carefully because mining hardware can age quickly when run in hot, dusty, or unstable environments.

Advantages of AvalonMiner 1246

AvalonMiner 1246 has the advantage of being a dedicated SHA-256 ASIC with industrial-level hashrate for Bitcoin mining.

Its 90 TH/s rating is far beyond what a normal CPU, GPU, or consumer computer can produce on SHA-256 mining.

The machine also has integrated air cooling and an integrated power supply accessory, which makes it easier to deploy than custom-built mining systems.

Because it is an older model, used units may sometimes be available at lower upfront cost than newer ASICs.

This can appeal to miners who already have cheap power, spare electrical capacity, and enough space for heat and noise.

AvalonMiner 1246 can also be useful for learning about real mining operations because it exposes users to pool setup, ASIC monitoring, power planning, and heat management.

For educational mining labs, the machine can demonstrate how proof-of-work hardware behaves in practice.

For home use, the main limitation is usually not technical complexity but electricity cost, heat, and noise.

Limitations of AvalonMiner 1246

The main limitation of AvalonMiner 1246 is that it is no longer among the most efficient ASIC miners by current standards.

At 38 J/TH, it may struggle in markets where electricity is expensive or where newer machines are competing with much better efficiency.

Another limitation is heat output, because 3420W of continuous power creates a large thermal load.

Noise is also a major limitation because 75 dB is too loud for many residential environments.

Hardware age can be another issue because used machines may have worn fans, stressed power supplies, degraded hashboards, or unknown repair history.

Shipping damage and poor seller disclosure can also create problems in the used ASIC market.

Mining revenue uncertainty is another limitation because Bitcoin price and difficulty can change faster than a miner’s payback plan.

AvalonMiner 1246 should therefore be evaluated as a business machine with operating costs, not as a simple passive income device.

AvalonMiner 1246 Compared With Modern Mining Needs

AvalonMiner 1246 helped represent a generation of high-performance air-cooled Bitcoin miners, but mining hardware has continued to improve.

The current Canaan official website shows newer Avalon product lines with much higher rated hashrates than the A1246 generation.

This matters because Bitcoin mining is a competitive market where efficiency improvements can pressure older machines.

When newer miners produce more hashrate per watt, older miners need cheaper electricity to remain competitive.

However, older miners may still have a role where electricity is very cheap, where heat can be reused, or where the hardware purchase price is low enough to justify the risk.

For example, some operators use ASIC heat for workshops, greenhouses, water systems, or cold-climate heating experiments.

Heat reuse does not remove the need for profitability analysis, but it can change the economics if the heat replaces another energy cost.

In any case, AvalonMiner 1246 should be judged by total cost of ownership rather than by hashrate alone.

Security and Network Role

AvalonMiner 1246 contributes to Bitcoin security only when it is actively hashing valid work for the network or a pool that mines valid blocks.

Proof-of-work security comes from the high cost of producing valid blocks and the difficulty of rewriting chain history.

Each miner adds a small amount of computational power to the wider mining ecosystem.

When many independent miners participate across different locations and energy sources, the network becomes harder to attack or censor.

However, an individual ASIC owner should understand that connecting to a pool also means trusting the pool’s payout rules and operational reliability.

A miner should review pool fee structure, payout method, server location, uptime, and transparency before connecting hardware.

Security also includes operational security at the owner level.

Operators should protect dashboard access, avoid exposing miner interfaces directly to the public internet, use strong network hygiene, and keep firmware sources trustworthy.

Who Might Use AvalonMiner 1246?

AvalonMiner 1246 may fit miners who already understand Bitcoin mining economics and have access to low-cost electricity.

It may also fit operators who want a lower-cost used ASIC for testing, training, or small-scale mining experiments.

It is less suitable for users who pay high residential electricity rates.

It is also less suitable for users who cannot handle loud noise, strong heat, and high-voltage power requirements.

New users should avoid buying AvalonMiner 1246 only because the machine appears cheap.

A cheap ASIC can become expensive if power cost, repairs, shipping, customs, downtime, and cooling are ignored.

Before buying, users should compare expected daily revenue with daily electricity cost and consider whether the hardware can realistically run long enough to recover its cost.

They should also think about resale value, spare parts, and whether the machine is already near the end of its profitable life.
