Kadena ASIC Miner

The Bitmain Antminer KA3 is an application-specific integrated circuit miner built for the Kadena algorithm. It delivers a hashrate of 166Th/s while drawing 3154W of power. The unit weighs 18kg and includes its own power supply. It is intended for operators mining KDA coins at scale.

Rack Installation and Noise

The miner ships as a complete unit with dual fans already fitted, so physical installation is limited to rack mounting and connecting the supplied power supply. No separate PSU sourcing or cabling assembly is required. The main operational constraint is the 75db noise output, which demands a dedicated ventilated room or sound-dampened enclosure. Ensure the electrical circuit can sustain the continuous 3154W load before powering on.

Deciding Specification Hashrate

The single figure that determines suitability is the 166Th/s hashrate on the Kadena algorithm. This rate fixes the expected KDA revenue against the fixed 3154W power draw. If your electricity cost makes that ratio profitable the miner fits; if not, no other specification changes the outcome.

Questions about this item

How do I confirm the Antminer KA3 is hashing at 166Th/s after setup?

Check the miner's web dashboard or mining pool statistics; a stable reading near 166Th/s with power draw around 3154W shows it is working as intended.

What comes in the box with the KA3 and what must I source separately?

The unit includes the integrated power supply; you only need to provide a suitable power cable, network connection and a Kadena wallet address.

Which KA3 version should I choose for Kadena mining?

The KA3 is a single model delivering 166Th/s at 3154W for the Kadena algorithm; there are no alternate capacities or versions to select.
