Purpose-built SHA-256 ASIC miner

The AFRNDK Antminer S19 82TH is a dedicated Bitcoin mining machine built on Bitmain’s S19 series architecture. It delivers a hashrate of 82 TH/s while drawing 2967 W, yielding an efficiency of 34.5 J/TH. The unit operates on a 220 V supply and connects via RJ45 Ethernet 10/100M.

Upgrade from earlier ASICs

This model improves on the S17 Pro and T19 with a custom 23 J/TH chip design and a 95 ± 3% TH/s target. The jump is worthwhile when electricity costs allow the 3250 W peak draw and the 75 dB noise level is acceptable. It replaces older rigs that cannot match the 34.5 J/TH efficiency figure.

Capacity and thermal limits

The miner maintains rated output between 5 °C and 40 °C at up to 95 % non-condensing humidity. Beyond 40 °C the protective logic throttles hashrate, and sustained operation above spec shortens chip life. Four fans move air through the 195 x 290 x 400 mm chassis weighing 14500 g.

Questions about this item

What are the exact dimensions of the Antminer S19 82TH unit?

The miner measures 195 mm wide, 290 mm deep and 400 mm tall, weighing 14500 g.

How do I connect the Antminer S19 to the network and what is the required voltage?

Connect the RJ45 Ethernet cable to a 10/100 M switch, then power the unit from a 220 V outlet; 12 V input is used internally.

How often should I clean the four fans and what operating temperature range must I maintain?

Inspect and clean all four fans every few months to keep airflow clear; the miner must run between 5 °C and 40 °C.
