AFRNDK Antminer S19 86TH/s SHA-256 Miner

This AFRNDK Antminer S19 is a dedicated SHA-256 ASIC miner built for Bitcoin. It delivers a rated hashrate of 86TH/s while drawing 3250W at the wall. The unit requires a 220V supply and connects via a 10/100M RJ45 Ethernet port. It ships new and is intended for operators running professional mining infrastructure.

Suited for 220V sites

The hardware fits facilities that can provide 220V circuits and handle 76dB of operating noise. It is not suitable for locations limited to lower voltages or for environments where sound levels must stay low. Buyers without access to industrial-grade power distribution or forced-air cooling should consider other options.

Deciding spec: 34.5 J/TH power efficiency

At 34.5 J/TH the miner sets the break-even threshold for electricity cost versus Bitcoin reward. If your power rate makes that efficiency profitable, the S19 86T earns its place; if not, the hardware will not cover its running cost.

Questions about this item

What are the physical dimensions and weight of the Antminer S19 86TH/s unit?

The miner measures 570 mm in length, 316 mm in width and 430 mm in height, with a gross weight of 16.0 kg.

How do I connect the Antminer S19 86TH/s to power and network, and what is the critical voltage requirement?

Connect the unit to a 220 V supply and link it via the RJ45 Ethernet port; applying the wrong input voltage can damage the hardware.

Which components of the Antminer S19 86TH/s typically require replacement over time?

The internal cooling fans are the primary wear items and will need periodic replacement to maintain the rated 76 dB noise level and thermal performance.
