Bitcoin SHA-256 ASIC Miner

The AFRNDK Antminer S19 86T is an application-specific integrated circuit miner built for the SHA-256 algorithm used by Bitcoin. It delivers a nominal hashrate of 86 TH/s while drawing 3250 W at the wall. The unit operates on a 220 V supply and connects via 10/100 M RJ45 Ethernet. Four integrated fans produce a noise level of 76 dB.

Suited for dedicated mining operations

This hardware suits operators with access to 220 V power and adequate cooling for 3250 W of continuous heat. The 76 dB noise level and 16.0 kg weight make it impractical for residential or office environments. Buyers without industrial-grade electrical infrastructure or sound-isolated hosting should consider alternative arrangements.

86 TH/s with 34.5 J/TH efficiency

At the rated 86 TH/s the miner achieves 34.5 J/TH, meaning each terahash consumes roughly 34.5 joules. The 3250 W power draw sets a firm ceiling on density; a 10 kW circuit can support only three units with minimal headroom. Performance scales linearly until thermal limits or power capacity are reached.

Questions about this item

What power supply does the Antminer S19 86T require to operate?

The miner requires a 220V input voltage; incorrect voltage can damage the unit.

Can I connect this miner using my existing 10/100M Ethernet switch?

Yes, the S19 86T uses a standard RJ45 Ethernet port rated at 10/100M for network connectivity.

How do I verify the Antminer S19 86T is hashing correctly after setup?

Check the dashboard for a reported hashrate of 86TH/s and power efficiency near 34.5 J/TH at 25°C.
