AFRNDK Antminer S21 SHA-256 ASIC Miner

This AFRNDK Antminer S21 is an ASIC miner built for the SHA-256 algorithm used by Bitcoin. It delivers a hashrate of 151 TH/s with a tolerance of plus or minus three percent. The unit requires a 220 V supply and connects to the network through an RJ45 Ethernet 10/100 M port.

Thermals noise and 2643 W power draw

Power consumption is rated at 2643 W while the miner operates in an ambient temperature range of 0 to 40 °C. The chassis measures 400 mm by 195 mm by 290 mm and weighs 15.2 kg. A power supply is included in the box.

Upgrade from older SHA-256 ASICs

The S21 reaches an energy efficiency ratio that exceeds 1 J/T for the first time in this product line. That efficiency gain makes the jump worthwhile when electricity cost per kilowatt-hour is high enough to offset the hardware outlay over the expected service life.

Otázky k tomuto produktu

How do I install the Antminer S21 151TH/s and what voltage mistake damages it?

Connect the included PSU to a 220 V supply, link the RJ45 Ethernet 10/100M port to your network, then configure the pool settings in the web UI. Supplying any voltage other than 220 V can permanently damage the miner.

What maintenance will the Antminer S21 151TH/s need over time?

Clean dust from the intake and exhaust vents regularly to keep airflow within the 0–40 °C ambient range. Replace fans when bearing noise appears, and reseat the power cables if the 2643 W draw becomes unstable.

What limit appears first when the Antminer S21 151TH/s runs continuously?

The 0–40 °C ambient temperature ceiling is the first constraint; sustained 2643 W heat output will push the unit past safe limits if cooling cannot maintain that range.
