AFRNDK Antminer S21+ Bitcoin ASIC

This ASIC miner is built for Bitcoin using the SHA-256 algorithm and delivers a hashrate of 235 TH/s. It draws 3564 W of power and is intended for operators who want maximum throughput from a single unit. The machine ships new and ready for deployment.

Ethernet interface and 220 V power requirement

The miner connects to the network through a single Ethernet port and requires a 220 V supply; incorrect voltage can damage the hardware. It operates between 10 °C and 40 °C with humidity from 10 % to 90 %. Two onboard fans produce a noise level of 75 dB to 85 dB.

235 TH/s hashrate at 3564 W

The hashrate of 235 TH/s and the power draw of 3564 W together determine the energy efficiency that decides whether this model fits a given electricity cost. No other specification outweighs this ratio for profitability calculations.

Questions sur cet article

What power supply and voltage does this miner need?

The unit requires a 220 V supply and draws 3564 W at the wall. Plan a dedicated circuit and a PSU rated for continuous load at that wattage.

Will the noise level suit a home or office environment?

The manufacturer rates the sound at 75 dB; the supplier also lists 85 dB. Both are comparable to a loud vacuum cleaner, so a separate, ventilated room is recommended.

What are the physical dimensions and operating temperature range?

The chassis measures 400 × 195 × 290 mm and is rated for 10–40 °C ambient temperature with 10–90 % relative humidity.
