Description

The Antminer KA3 from Bitmain achieves a maximum hashrate of 166Th/173Th and consumes 3,154W while mining Kadena (KDA).

Bitmain designed the Antminer KA3 as a high-performance ASIC miner for the Kadena (KDA) cryptocurrency, utilizing the Blake2S algorithm. Bitmain launched the KA3 in September 2022, and it quickly dominated the market as the most powerful and efficient Kadena miner, setting new benchmarks for hash rate and energy efficiency.

The Antminer KA3 delivers an impressive hash rate of 166 terahashes per second (TH/s) and draws 3,154 watts of power, resulting in an energy efficiency of 19 joules per terahash (J/TH). This model outperforms previous Kadena miners by up to 137% at the time of its release. Bitmain equips the KA3 with its advanced 19-series chipset and a robust air-cooling system featuring four high-speed fans, which maintain stable operation and dissipate heat effectively during continuous, demanding workloads.

Bitmain constructs the KA3 with durability and practicality in mind. The unit measures approximately 430 x 195.5 x 290 mm (without packaging) and weighs around 16.1 kg. You can easily integrate the miner into professional setups, thanks to its support for RJ45 Ethernet 10/100M network connectivity. The recommended operating environment ranges from 0°C to 40°C, with a non-condensing humidity tolerance of 10% to 90% and an altitude limit of up to 2,000 meters.

The KA3 generates between 75 and 80 decibels of noise during operation, which makes it unsuitable for home or office use and better suited for mining farms or industrial settings. Bitmain offers a 180-day warranty for this model.

You can access the KA3’s intuitive, web-based user interface to monitor performance metrics in real time and configure settings easily. Both seasoned miners and newcomers will find the interface accessible. Profitability depends on factors such as electricity costs, Kadena’s market price, and network mining difficulty. With its high efficiency and robust build, the Antminer KA3 stands out as a top choice for miners who want to maximize Kadena mining returns while keeping operational costs low.

In summary, Bitmain’s Antminer KA3 leads the Kadena mining market by combining exceptional hash rate, industry-leading efficiency, and reliable build quality, making it a preferred solution for professional and large-scale mining operations.
