Avalon A1566 SHA-256 ASIC Miner

The Avalon A1566 is a SHA-256 ASIC miner built for Bitcoin mining operations. It delivers a nominal hashrate of 191 TH/s with a tolerance of minus five to plus five percent. The unit requires a 200 to 300 volt AC supply and the manufacturer specifies 220 volts as the required input voltage. It connects to the network through an Ethernet interface.

18.5 J/TH Power Efficiency Rating

Power efficiency is rated at 18.5 joules per terahash with a tolerance of minus five to plus five percent. This figure determines the electricity cost per unit of hashing work and is the primary specification for evaluating operating expense. Typical power draw is listed as 3240 watts with a tolerance of minus ten to plus ten percent, while the nameplate rating is 3420 watts.

Thermal Performance At 75 dB Acoustic Output

Two 12050 fans provide forced-air cooling and produce a noise level of 75 decibels. The operating temperature range is five to forty-five degrees Celsius, allowing sustained operation in typical data-hall environments. The chassis measures 306 by 405 by 442 millimetres and weighs 12.8 kilograms.

Questions about this item

What does the 191 TH/s hashrate mean once the Avalon A1566 is running in a rack?

It delivers roughly 191 trillion SHA-256 hashes per second with a tolerance of minus five to plus five percent, drawing 3420 W at the wall for an efficiency near 18.5 J/TH.

The specs list Ethernet — what does that interface cap in practice?

The single Ethernet port carries stratum work and telemetry; throughput is limited by the pool and network, not by the miner itself.

What clearance and power feed does the 306 x 405 x 442 mm chassis need to fit and mount safely?

Allow at least the stated 306 mm width, 405 mm depth and 442 mm height plus airflow space, and supply 200–300 V AC at 220 V nominal to avoid damage.
