Product type and target user

The Antminer S21++ 216T is a SHA256 ASIC miner built for Bitcoin, Bitcoin Cash and Bitcoin SV networks. It delivers a typical hashrate of 216 TH/s at 3564 W with 16.5 J/TH efficiency. The unit includes an integrated power supply and uses air cooling. It is intended for operators running 220-277 V AC power infrastructure.

Operational profile and limits

The miner suits facilities that can supply 20 A per unit on single-phase 220-277 V circuits and tolerate 76 dBA noise at 30 °C ambient. It operates from -20 °C to 45 °C and 10-90 % humidity up to 2000 m altitude. Sites without adequate voltage range, current capacity, cooling for 3.5 kW heat output or noise isolation should consider other hardware.

Efficiency as the deciding spec

At 16.5 J/TH the power efficiency determines whether electricity costs allow profitable operation at a given tariff. The hashrate may vary by ±3 % and wall power by ±5 %, so the effective efficiency range drives the final profitability calculation.

Questions about this item

What power supply is required for the Antminer S21++ 216T?

The unit operates on single-phase AC input between 220 and 277 volts at 50 to 60 Hz, drawing up to 20 amps. A compatible PDU or outlet rated for that voltage and current is essential.

How much heat and noise does the miner produce in a typical room?

At 25 °C ambient the wall power is 3564 W, so nearly all of that becomes heat. The fans reach 76 dBA at 30 °C, which is comparable to a loud vacuum cleaner and requires dedicated ventilation.

What are the physical space and weight allowances I should plan for?

The chassis measures 450 by 219 by 293 mm and weighs 21.5 kg. The shipping carton grows to 630 by 350 by 430 mm and 24.5 kg, so allow clearance for rack depth and lifting access.
