Rectangular metal ASIC miner with four large fans, Ethernet and USB ports, 2021 AvalonMiner 1066 Pro

AFRNDK

AFRNDK AvalonMiner 1066 Pro 55Th/s 3300W SHA-256 ASIC Miner

SKU CH-FNH0-Z04CW

SHA-256 ASIC miner delivers 55 Th/s at 3300 W with 60 J/T efficiency using 342 16 nm chips, four 12038 fans, Ethernet and USB 2.0, and requires 220–260 V operation

Options Avalon 1066 PRO

  • Delivers 55 TH/s for SHA-256 mining
  • Power efficiency of 60 J/T ±5% at 25 °C
  • 342 16 nm A3205 chips drive hashrate
  • Four 12038 fans cool from -5 °C to 35 °C
  • Requires 220 V to 260 V supply for operation

Purpose-built SHA-256 miner

The AFRNDK AvalonMiner 1066 Pro delivers a hash rate of 55 Th/s using the SHA-256 algorithm, making it suitable for Bitcoin and Bitcoin Cash mining. It is an ASIC device designed for operators who need dedicated hashing hardware rather than general-purpose compute.

Deployment and power needs

The unit ships with a power supply and connects via Ethernet and USB 2.0. It requires a 220 V to 260 V supply and draws up to 3300 W. Four 12038 fans provide cooling across an operating range of -5 °C to 35 °C. The metal chassis uses a reinforced design intended to simplify maintenance.

Upgrade context

The miner uses 342 Canaan 16 nm A3205 chips with a 256-bit memory interface clocked at 600 MHz and a power ratio of 60 J/T ±5 %. It replaces earlier Avalon models that fall short of the 55 Th/s target or exceed the 3300 W envelope. The efficiency jump is worth it when electricity cost and infrastructure can support the voltage and thermal requirements.
