Product Details

Canaan Avalon A1566I 249TH Remarkably Quiet Air Cooled SHA-256 Bitcoin Miner

Something unusual happens when you put 249 TH/s and 35 dB on the same spec sheet. Standard Bitcoin miners at this hashrate run 75 dB, which sounds like a vacuum cleaner in the same room. The Canaan A1566I operates at whisper level. That 40 dB gap translates to roughly 99 percent reduction in perceived loudness.

This changes where Bitcoin mining can physically happen. Apartments. Home offices. Small businesses that would never tolerate industrial noise. Workshops attached to living spaces. The A1566I goes into rooms where every other 200+ TH/s miner gets immediately rejected on noise alone.

The trade off is efficiency. At roughly 18.1 J/TH versus the A16XP at 12.8 J/TH, you pay about $1.50 more per day in electricity per unit for the privilege of silence. That is the real cost of quiet: not a hardware premium, but an ongoing electricity premium that either makes sense for your situation or does not.

220 to 277V input only. No 110V compatibility. You need commercial grade power or a dedicated 220V circuit. At 4,500W, the unit draws roughly 20.5 amps at 220V. 13.2 kg at 301 x 192 x 292mm in standard Canaan Avalon chassis. Ethernet connectivity. Canaan trades on NASDAQ as CAN and built the first commercial Bitcoin ASIC.

For comparison: the Bitmain S23 produces 318 TH/s at 75 dB. The Bitdeer A3 Pro reaches 290 TH/s at 75 dB. Both are faster, both are louder, and both are banned from quiet spaces. The A1566I occupies a deployment niche that competing hardware simply cannot access.

Avalon A1566I 249TH Ultra Quiet Air Cooled Bitcoin Miner

Canaan A1566I. 249 TH/s SHA 256 at 4,500W and 35 dB. Industrial hashrate at home friendly noise. One of the only 200+ TH/s Bitcoin miners that operates at conversation whisper level.

Every competing miner at this hashrate runs at 75 dB. The A1566I is 40 dB quieter, roughly 99 percent reduction in perceived loudness. Enables deployment in apartments, offices, and noise restricted zones where 75 dB industrial mining is impossible.

Trade off: approximately 18.1 J/TH versus the A16XP at 12.8 J/TH. Roughly $1.50 more daily electricity for silence. 220 to 277V (not 110V). 13.2 kg at 301 x 192 x 292mm. Canaan NASDAQ CAN. Ethernet. 5 to 35 degrees.

Silent operation at 35 dB means deployment anywhere: living rooms, bedrooms, offices. No noise considerations. Focus purely on power capacity and Ethernet connectivity. Home mining at its most accessible.

Canaan firmware provides pool configuration, hashrate monitoring, and operational alerts. Evaluate pricing against competing models at this hashrate tier for best fleet value.
