ASIC Bitcoin miner for SHA-256
The AFRNDK Antminer S21+ is an application-specific integrated circuit built to mine Bitcoin using the SHA-256 algorithm. It delivers a hashrate of 225TH/s while drawing 3564W of power. The unit is intended for operators who run dedicated mining infrastructure and can supply 220V input power. It is not suited for buyers who need a general-purpose computer or a quiet home device.
Ethernet interface and dual-fan cooling
The miner connects to the network through a single Ethernet port and uses two built-in fans to move air through the chassis. No additional controllers, cables or software licences are mentioned in the supplied data. The package therefore assumes the operator already has a compatible network switch, a 220V power distribution unit and a rack or shelf that accepts the 400 x 195 x 290mm form factor. Buyers who lack these supporting items must source them separately.
Environmental limits of 10 to 40 °C
Operation is specified between 10 °C and 40 °C with relative humidity from 10 % to 90 %. The manufacturer also lists a noise level of 75 dB, while another data point shows 85 dB; the higher figure should be planned for in shared spaces. The 220V supply requirement is strict — incorrect voltage can damage the hardware. Sites without stable 220V power, adequate cooling capacity or sound isolation cannot run this miner reliably.

Soalan tentang produk ini
Which part will likely need replacement first on the Antminer S21+?
The two cooling fans are the only moving parts and will wear out before the ASIC boards under continuous operation.
What limit appears first when the Antminer S21+ runs continuously at 3564 W?
The operating temperature ceiling of 40 °C is reached before any power or hashrate ceiling, so inlet cooling capacity becomes the bottleneck.
How loud and how hot does the Antminer S21+ get during all-day mining?
It produces 75 dB to 85 dB of noise with its dual fans while exhausting enough heat to keep the chassis within the 10–40 °C operating window at 3564 W.
