Bitmain Antminer KA3 166Th

The Bitmain Antminer KA3 166Th is an ASIC miner built for the Kadena blockchain using the Blake2S algorithm. It delivers a hash rate of 166 Th/s while drawing 3154 W from its included power supply. The unit measures 195 x 290 x 430 mm and weighs 16100 g. Four fans provide air cooling and produce a noise level of 80 dB.

Capacity and headroom 166 Th/s

At 166 Th/s the machine sits at the upper end of current Kadena ASIC performance, so it can sustain profitable mining while network difficulty remains moderate. Power draw of 3154 W sets a firm ceiling on operating cost; any rise in electricity price or drop in KDA value will shrink margins quickly. The 80 dB fan noise also limits deployment to dedicated spaces rather than offices or homes.

Release date September 2020

The Antminer KA3 launched in September 2020, making it a mature design with established firmware support and known reliability in the field. Buyers should verify that the 3154 W power requirement matches their facility’s electrical capacity before purchase. No other specifications determine suitability; the release date simply confirms the hardware generation.

Spurningar um þessa vöru

Will the Antminer KA3 166Th fit on a standard 19-inch rack shelf that is 430 mm deep?

The unit measures 195 mm wide by 290 mm high by 430 mm deep, so it matches the depth of a typical 19-inch rack shelf while leaving space for cable routing at the rear.

How can I confirm the Antminer KA3 166Th is hashing at the rated 166 TH/s after power-up?

Log into the miner's web interface; the dashboard shows real-time hash rate per board and a total that should read 166 TH/s when all four hash boards are healthy.

Does the Antminer KA3 166Th shipment include the 3154 W power supply or must it be ordered separately?

The 3154 W power supply is included in the box along with the miner chassis, four cooling fans and the necessary internal cables.
