Antminer KA3

Description

Antminer KA3

Are you looking for a powerful ASIC miner designed specifically for Kadena mining? The Antminer KA3 from Bitmain is a high-performance miner built for the Blake2S algorithm, delivering strong hashing power with efficient energy consumption for professional mining operations.

The Antminer KA3 operates on the Blake2S algorithm, making it ideal for mining Kadena (KDA) and other Blake2S-based cryptocurrencies. This miner delivers a maximum hashrate of about 166 TH/s while consuming approximately 3154W of power, resulting in an energy efficiency of around 19 J/TH.

Released in September 2022, the KA3 is built with Bitmain’s specialized ASIC architecture optimized for Kadena mining workloads. With 166 TH/s hashing power and around 3.15 kW power consumption, it provides significantly higher performance compared to earlier Kadena ASIC miners.

The Antminer KA3 uses a high-performance air-cooling system with multiple fans to maintain stable operating temperatures during continuous mining workloads. The miner is designed for professional mining farms and typically operates with a noise level around 75–80 dB, making it suitable for industrial mining environments.

The unit measures approximately 430 × 195 × 290 mm, weighs about 16.1 kg, and connects through a standard RJ45 Ethernet interface for network communication and remote management. It supports 200–240V power input and operates reliably in environments with temperatures between 0°C and 40°C and humidity levels of 10–90% (non-condensing).

With 166 TH/s Blake2S hashing power, 3154W power consumption, and Bitmain’s proven ASIC technology, the Antminer KA3 provides a powerful and efficient solution for miners focused on Kadena (KDA) and Blake2S-based cryptocurrency mining.
