Antminer KA3 166Th/s – Bitmain Kadena ASIC Miner

The Antminer KA3 is specified at 166 ± 3 % TH/s using the Blake2S algorithm (for Kadena/KDA) and a power consumption of about 3,154 W at 25 °C.

It achieves an efficiency of approximately 19.0 J/TH under standard conditions.

As the miner draws ~3.15 kW and produces significant heat and noise, you’ll need suitable electrical supply (200–240 V, adequate wiring), proper ventilation/cooling, and check ambient conditions. Derived from spec and user commentary.

The KA3 was released in September 2022. It currently leads in Kadena mining hashrate for its class.

The product supports standard mining-pool connectivity, firmware updates and monitoring via web UI and Ethernet. Some vendors mention improved cooling design and dust reduction features.
