Canaan Avalon 1146 Pro (63TH)

63 TH/s SHA-256 at 3,276W and 52 J/TH efficiency. ±3 to ±5 percent hashrate tolerance produces real world output between approximately 60 and 66 TH/s. This is Canaan's A11 chip generation from August 2020, approximately five generations behind current hardware. For reference, current generation air cooled Bitcoin miners produce 235 to 336 TH/s at 10.9 to 16 J/TH from the same single phase power class.

At standard electricity rates, no. MillionMiner's calculator shows -$4.14 daily at $0.08 per kWh. At $0.05 per kWh: -$1.78 daily. The 1146 Pro reaches positive margin only at approximately $0.025 per kWh or below at April 2026 BTC prices and 139T network difficulty. Stranded energy operations (flare gas, excess hydro, behind the meter solar) where electricity approaches zero cost represent the viable deployment scenario. Higher BTC prices shift the break even electricity rate upward.

Four realistic use cases. Stranded energy: operators with near zero cost electricity (flare gas, excess hydro, behind the meter solar) where any positive hashrate generates incremental revenue regardless of efficiency. Education: learning Bitcoin mining setup, pool configuration, firmware management, and fleet operations on low value hardware before investing in current generation equipment. Heating: 3,276W produces approximately 11,171 BTU per hour, supplementing building heating in cold climates where the mining electricity displaces heating cost. Heritage: Canaan developed the first commercial Bitcoin ASIC in 2013, and the 1146 Pro represents a functional piece of that history.

The efficiency gap is substantial. 1146 Pro at 63 TH/s and 52 J/TH. Bitmain S21+ at 235 TH/s and 16 J/TH. Bitmain S21 XP at 270 TH/s and 13.5 J/TH. Bitmain S23 at 318 TH/s and 14 J/TH. Bitdeer A4 Pro Air at 336 TH/s and 10.9 J/TH. The A4 Pro Air delivers approximately 5.3 times more hashrate at approximately 4.8 times better efficiency from the same power draw class. For operators with access to standard electricity rates, current generation hardware delivers fundamentally different economics.

Universal 100 to 240V AC input with built in PSU. Runs on any standard outlet worldwide including 110V North American residential. At 3,276W on 110V the unit draws approximately 29.8 amps, requiring a dedicated 30 amp circuit. At 220V approximately 14.9 amps on a standard 20 amp commercial circuit. No external PSU needed since the power supply is integrated into the chassis.

75 dB industrial noise from four cooling fans. Same acoustic level as current generation Bitcoin ASICs (Bitmain S21 XP, S23, Bitdeer A4 Pro Air). Requires dedicated mining space: warehouse, outbuilding, garage with sound isolation, basement with ventilation. Not suitable for residential rooms or shared offices. At this noise level the deployment infrastructure cost is the same whether running a 63 TH/s legacy miner or a 336 TH/s current generation unit.

Canaan specification: -5 to 35 degrees Celsius. MM lists 5 to 45 degrees Celsius which does not match Canaan's documentation. The -5 degree low end supports cold climate deployment without facility heating, useful for garage or container deployments in northern regions. The 35 degree ceiling is tighter than typical modern ASICs (which tolerate 40 to 50 degrees Celsius) and means Gulf region or hot climate deployments require active cooling to stay below 35 degrees Celsius during summer months.

Canaan Inc. (NASDAQ: CAN) developed the Avalon, the first commercially produced Bitcoin ASIC miner, in 2013. This literally created the ASIC mining industry before Bitmain entered the market. Canaan IPO'd on NASDAQ in November 2019 as the first publicly listed ASIC mining hardware company. Current product line includes the A14 and A15 series at 150+ TH/s. While the 1146 Pro is legacy hardware, it carries Canaan's established firmware ecosystem, manufacturer warranty structure, and publicly audited corporate backing.

All SHA-256 proof of work cryptocurrencies. Primary: Bitcoin (BTC). Secondary: Bitcoin Cash (BCH), Bitcoin SV (BSV), eCash (XEC), Peercoin (PPC), DigiByte (DGB SHA-256 chain), Namecoin (NMC), Acoin, Curecoin, Terracoin, and other SHA-256 chains. AuxPoW merged mining through supporting pools (F2Pool, ViaBTC) allows simultaneous BCH and NMC revenue without reducing BTC hashrate. Alternative SHA-256 coins may offer marginally better revenue per terahash than BTC at certain network conditions.

Yes. At 3,276W continuous the 1146 Pro produces approximately 11,171 BTU per hour, equivalent to a medium space heater. In cold climate homes (Scandinavia, Canada, northern US), running the miner in a utility room, basement, or garage during heating season displaces electric heating cost. If your alternative heating source costs $0.08 per kWh in electricity, the mining operation effectively runs at a net cost of only the difference between mining electricity and displaced heating electricity, plus whatever BTC revenue it produces. During summer months, the same heat output becomes a liability requiring ventilation or exhaust.

331 x 195 x 292 mm chassis at 12.8 kg per MM and PandaBox specifications. Some distributor documentation lists 306 x 405 x 442 mm which may reflect a different variant or the complete assembly with external controller housing. Four cooling fans with front intake and rear exhaust. Built in PSU means no external power supply box to accommodate. Compact enough for shelf placement in a dedicated mining room.

Yes. The 1146 Pro AC variant includes an integrated power supply accepting 100 to 240V AC input directly. No external PSU to purchase, match, or configure. Plug the included power cable into any standard grounded outlet. Note: some Canaan Avalon models ship as DC variants requiring a separate external PSU and AUC3 controller. Verify with MillionMiner that the specific unit ships as the AC integrated variant.

Four step setup. Connect the 1146 Pro to a 100 to 240V outlet using the included power cable (verify circuit amperage capacity: 30 amp at 110V, 20 amp at 220V). Connect Ethernet cable to router or switch. Find miner IP through router DHCP, Canaan IP reporter tool, or network scanner. Open Canaan web interface, configure SHA-256 pool URL and BTC wallet address, change default credentials. Verify hashrate reaches 60+ TH/s within 10 minutes.

Every major Bitcoin SHA-256 pool accepts the 1146 Pro through standard Stratum protocol. Foundry USA, AntPool, F2Pool, ViaBTC, Braiins Pool, Luxor, OCEAN, Mining Pool Hub, and all other SHA-256 compatible pools. Pool selection is pool preference, not hardware limitation. Pool fees typically 0 to 2.5 percent. For legacy hardware generating small daily revenue, lower fee pools improve net returns proportionally more than on high hashrate hardware.

Canaan Avalon firmware ecosystem is less extensive than Bitmain's. BraiinsOS+ does not support Canaan Avalon hardware. Most 1146 Pro operators run stock Canaan firmware. Some community firmware projects exist for Avalon hardware tuning but adoption is limited. For operators prioritizing firmware optimization or undervolting/overclocking capability, Bitmain Antminer alternatives offer more developed third party firmware support.

MillionMiner hosting facilities accept the 1146 Pro on standard single phase power. However, hosting economics for legacy hardware at 52 J/TH are challenging: the daily electricity cost at hosted industrial rates ($0.04 to $0.06 per kWh) runs $3.14 to $4.72 against approximately $2.15 daily revenue, still producing negative margins at most hosted rate tiers. Hosting makes economic sense only if the operator's facility rate drops below approximately $0.025 per kWh. Contact MillionMiner for availability.

Standard air cooled ASIC maintenance. Quarterly dust cleaning of four fan intake and exhaust grilles. Annual fan bearing inspection for wear (vibration, clicking). Monitor hashrate through Canaan web interface for degradation. The 1146 Pro has been in production since August 2020, meaning units in the field have established multi year reliability records. Canaan's A11 chip architecture is proven through years of continuous operation across thousands of deployed units.

MillionMiner also lists the Canaan Avalon A1366I (122 TH/s, newer A13 generation). The A1366I delivers approximately 94 percent more hashrate at significantly better efficiency per terahash from the same power draw class. For operators comparing within Canaan's lineup, the A1366I is the modern option. The 1146 Pro is the deep legacy option at deep discount pricing. Canaan's own current flagship models (A14 series at 150+ TH/s) deliver approximately 2.4 times more hashrate at 3 to 4 times better efficiency.

Only in specific scenarios. At standard electricity rates ($0.05 to $0.12 per kWh), the 1146 Pro loses money daily at April 2026 conditions. It is not a profitable mining investment at normal power costs. Buy the 1146 Pro if: you have access to electricity below $0.025 per kWh (stranded energy, flare gas, excess hydro), you want functional legacy Bitcoin mining hardware for educational or training purposes, you are deploying in a cold climate where 3,276W of mining heat displaces electric heating costs, or you are a collector valuing Canaan's historical significance as the originator of commercial ASIC mining. For profitable Bitcoin mining at standard electricity rates, current generation hardware (Bitmain S21 XP at $4,051, Bitmain S23, Bitdeer A4 Pro Air at $4,999) delivers fundamentally different economics.

For profitable Bitcoin mining at standard electricity rates: Bitmain Antminer S21+ (235 TH/s, 16 J/TH, $3,083), Bitmain S21 XP (270 TH/s, 13.5 J/TH, $4,051), Bitmain S23 (318 TH/s, 14 J/TH), Bitdeer SealMiner A4 Pro Air (336 TH/s, 10.9 J/TH, $4,999). All deliver positive daily margins at $0.08 per kWh. For hydro deployment: Bitmain S23 Hydro (580 TH/s, 9.5 J/TH), Bitdeer A4 Ultra Hydro (886 TH/s, 9.45 J/TH). For quiet home Bitcoin mining: NerdMiner NerdQaxe++ (4.8 TH/s, lottery mining educational), Bitaxe Gamma (1.2 TH/s, open source solo).
