AFRNDK Antminer S19 82T SHA-256 ASIC

The AFRNDK Antminer S19 82T is an ASIC miner built for the SHA-256 algorithm with a hashrate of 82Th/s. It draws 3250W of power and operates at a noise level of 80dB using four fans. The unit requires a 220V input voltage to function correctly. This hardware targets Bitcoin mining operations seeking high throughput.

Suited for dedicated Bitcoin mining farms

This miner suits operators with access to 220V industrial power and facilities that can accommodate 80dB noise levels. The 3250W draw demands robust electrical infrastructure and cooling capacity. Hobbyists or home users without dedicated high-voltage circuits and sound isolation should look at lower-power alternatives. The SHA-256 focus limits it to Bitcoin and compatible forks only.

82Th/s headroom at 3250W

At 82Th/s the machine delivers strong SHA-256 throughput for current network difficulty. Power efficiency sits at 34.5 J/TH with a noted chip capability of 23 J/TH under optimal conditions. The 3250W ceiling defines the operational limit; exceeding available voltage or cooling will throttle performance. Headroom exists until difficulty growth outpaces the fixed hashrate.

Questions about this item

Will the miner run on a standard 220 V circuit, and how much power does it draw?

The unit requires 220 V input and draws 3250 W with a ±5 % tolerance; using the wrong voltage can damage the hardware.

What is the real-world energy efficiency of this model?

Power efficiency is rated at 34.5 ±5 % J/TH, and the custom Bitmain chip can reach as low as 23 J/TH under optimal conditions.

How loud is the miner when all four fans are running?

Noise level is specified at 80 dB, which is comparable to a busy street or a loud vacuum cleaner.
