Bitcoin ASIC Miner

The AFRNDK Antminer S21+ is an ASIC miner built for the SHA-256 algorithm and Bitcoin. It delivers a hashrate of 216 TH/s with a power draw of 3564 W. The unit ships with a power supply and connects via Ethernet. It operates between 10 °C and 40 °C at 10 % to 90 % humidity.

High-Density Mining Operations

This machine suits operators who run 220 V infrastructure and can handle 75 dB noise from two fans. The 400 x 195 x 290 mm form factor fits standard rack layouts. Buyers without 220 V supply or noise-tolerant facilities should look at other hardware.

216 TH/s Hashrate at 3564 W

The decisive specification is the 216 TH/s hashrate at 3564 W power consumption. This ratio determines daily Bitcoin yield and electricity cost. Verify your site can provide 220 V and adequate cooling before purchase.

Questions about this item

What input voltage does the Antminer S21+ require?

The unit requires a 220 V supply; applying a different voltage can damage the miner.

Will the Antminer S21+ fit in a standard 19‑inch rack?

The chassis measures 400 × 195 × 290 mm, so verify your rack depth and width before mounting.

What cooling and noise levels should I expect in a typical room?

Two built‑in fans produce about 75 dB and the operating temperature range is 10‑40 °C with 10‑90 % humidity.
