bitmain Antminer S19 (86Th) mining hardware

SKU CH-H34X-02W9T

SHA-256 ASIC miner delivering 86 TH/s at 3250 W with 34.5 J/TH efficiency, RJ45 Ethernet, 75 dB noise, 5–40 °C operating range

  • Delivers 86 TH/s hashrate for strong Bitcoin mining throughput
  • Operates at 34.5 J/TH power efficiency to lower electricity cost per coin
  • Runs between 5 and 40 °C for stable performance in varied environments
  • Connects via RJ45 Ethernet 10/100M for reliable pool communication
  • Emits 75 dB noise level so operators can plan sound management

Built for SHA-256 mining

The Bitmain Antminer S19 (86Th) is an ASIC miner engineered for the SHA-256 algorithm used by Bitcoin and Bitcoin Cash. It delivers a nominal hashrate of 86 TH/s with a tolerance of ±3% and draws approximately 3250 W at the wall. The unit measures 195 x 290 x 400 mm and weighs 14500 g, requiring a 12 V supply and an environment between 5 and 40 °C.

Included power supply changes deployment

A power supply ships in the box, removing the need to source a separate high-wattage unit rated for 3250 W ±5%. The integrated PSU connects directly to the hash boards, shortening cable runs and reducing potential points of failure. New firmware adds faster startup and an intelligent control mechanism that monitors chip health and adjusts frequency to keep efficiency near 34.5 J/TH ±5%.

86 TH/s headroom and limits

At stock settings the miner sustains 86 TH/s while consuming 3250 W, yielding roughly 34.5 J/TH. Custom chips can reach 23 J/TH in optimised conditions, but the factory profile targets stability over peak efficiency. The RJ45 10/100M link is adequate for stratum traffic; latency or bandwidth beyond 100 Mbit/s provides no benefit. Operation above 40 °C or below 5 °C, or in condensing humidity, will throttle or halt the device.

Questions about this item

What are the exact dimensions and weight of the Antminer S19 (86Th)?

The miner measures 195 mm wide by 290 mm deep by 400 mm high and weighs 14500 g.

What power supply and circuit are required for the 3250 W rating?

The unit runs on 12 V input and draws 3250 W with a ±5 % tolerance, so a dedicated high-amperage circuit at your local mains voltage is needed.

What temperature and humidity range does the miner tolerate?

It operates from 5 °C to 40 °C and 5 % to 95 % relative humidity, non-condensing.
