What this miner does

The AFRNDK S19 is a SHA-256 ASIC built for Bitcoin and Bitcoin Cash mining. It delivers a hashrate of 86Th/s while drawing 2967W at the wall. The unit ships with an integrated power supply and connects to the network through a 10/100M RJ45 port. Noise during operation reaches 76dB.

Who should buy it and who should not

This hardware suits operators with access to 220V mains power and a location that tolerates 76dB continuous sound. Sites limited to lower mains voltage or noise-sensitive environments should look elsewhere. The four-fan cooling system demands adequate airflow and rack space measuring 400mm by 195.5mm by 290mm.

The spec that decides fit

Power efficiency is rated at 34.5J/Th, which directly determines daily electricity cost per terahash. At 2967W total draw the miner requires a 220V circuit capable of sustaining that load without derating. If your facility cannot meet the voltage or power density requirement the S19 will not operate reliably.

Questions about this item

What power circuit must I already have for the S19 to run?

The S19 requires a 220V supply and draws 2967W, so a dedicated 220V circuit rated for at least 16A is needed before installation.

Will the S19’s RJ45 10/100M port work with my older 100M switch?

Yes, the Ethernet interface is 10/100M and will link at 100M with an older switch, which is sufficient for stratum traffic.

How can I confirm the S19 is hashing at the rated 86Th/s after setup?

Check the miner’s web dashboard or pool worker page; a sustained rate near 86Th/s with 34.5J/Th efficiency shows it is operating as specified.
