Avalon A1566 Bitcoin ASIC Miner

The Avalon A1566 is a SHA-256 ASIC miner built for Bitcoin mining. It delivers a nominal hashrate of 188TH/s with a tolerance of minus 5% to plus 5%. The unit draws 3240W at the wall with a 10% variance and achieves 18.5J/TH efficiency. It ships new from the manufacturer CANAAN.

Suited for 220V operations only

This miner requires a 200-300V AC supply and will be damaged by incorrect voltage. Facilities without access to that voltage range should look elsewhere. The 75dB noise level and 12.8kg weight also demand a dedicated rack or shelf. Hobbyists on standard household circuits cannot use it safely.

188TH/s at 18.5J/TH efficiency

The single figure that decides fit is the 18.5J/TH power efficiency at 188TH/s. Operators compare this metric directly against their electricity cost to determine profitability. Cooling is handled by two 12050 fans within a 306 x 405 x 442mm chassis. Network connectivity is via Ethernet.

Questions about this item

What are the exact dimensions and weight of the Avalon A1566 for rack planning?

The unit measures 306 x 405 x 442 mm and weighs 12.8 kg, so allow that footprint and load capacity in your rack or shelf layout.

Which steps during installation are critical to avoid damaging the A1566?

Connect only to a 200–300 V AC supply that delivers 220 V nominal; applying the wrong voltage can permanently damage the miner before you even configure the Ethernet link.

What ongoing maintenance does the A1566 require and which parts wear out first?

The two 12050 cooling fans are the primary wear items; expect to clean dust from them regularly and replace them when noise exceeds 75 dB or airflow drops enough to push the 5–45 °C operating range.
