SHA-256 ASIC miner at 235 Th/s

This Antminer S21++ unit delivers a typical hashrate of 235 Th/s on the SHA-256 algorithm used by Bitcoin, Bitcoin Cash and Bitcoin SV. It draws 3878 W at the wall with a typical efficiency of 16.5 J/Th. The machine ships with an integrated power supply and operates on 220–277 V AC single-phase input.

Suited for hosted or industrial sites with 220–277

The miner requires a 220–277 V AC circuit rated for at least 20 A and produces 76 dBA of noise at 30 °C ambient. Those limits rule out most residential or office environments. Operators without adequate cooling, power infrastructure or noise isolation should consider alternative hardware.

16.5 J/Th efficiency at the wall

Power efficiency of 16.5 J/Th determines the electricity cost per terahash and is the primary metric for profitability calculations. Actual wall power and efficiency may vary by ±5 % and hashrate by ±3 %. The unit operates between –20 °C and 45 °C at altitudes up to 2000 m.

商品問答

Does the Antminer S21++ 235T ship with the power supply and power cord included, or must they be purchased separately?

The miner comes with the power supply and power cord already included in the box.

What does the 16.5 J/TH efficiency rating mean for daily electricity cost?

At 235 Th/s the unit draws about 3878 W, so each terahash consumes 16.5 joules; multiply your local kWh rate by 93 kWh to estimate daily power cost.

How much does the hashrate actually vary once the miner is running in a rack?

The manufacturer states the real-world hashrate fluctuates within ±3 % of the 235 Th/s typical figure, while power draw can vary by ±5 %.
