AFRNDK Antminer KA3 173TH/s 3154W Blake2S ASIC mining hardware

Blake2S ASIC Miner for KDA

The AFRNDK Antminer KA3 is a dedicated ASIC mining barebone system built for the Blake2S algorithm and the Kadena network. It delivers a rated hashrate of 173 TH/s while drawing 3154 W of power. The unit is designed for operators who run Kadena workloads continuously and need a single-purpose device rather than a general-purpose GPU rig.

220 V Ethernet-Connected Barebone

The miner requires a 200–240 V supply and connects to the network through a single Ethernet interface. Four internal fans move air through the 195 x 290 x 430 mm chassis, which weighs 16100 g. No additional compute cards, memory modules or storage drives are needed; the device is a self-contained hashing appliance that only needs power, a network drop and adequate rack or shelf space.

Sustained Load at 5–40 °C Ambient

Rated for continuous operation between 5 °C and 40 °C with 10–90 % relative humidity, the KA3 maintains its 173 TH/s output as long as intake air stays within that envelope. The 80 dB noise level is constant under full load, so acoustic planning is necessary for shared or residential sites. Stable 220 V input and unrestricted airflow are the primary factors that keep long-term performance consistent.
