How efficient is the Antminer S9?

The Antminer S9 runs at 98 J/TH — joules per terahash is the number that decides mining profitability. The classic that mined an era — today a heater with a hobby.

How much power does the Antminer S9 use?

Typical wall draw is 1,323 W, which at a reference $0.10/kWh costs about $3.18 per day in electricity. Scale linearly to your own rate — the electricity price is the whole business.

Is the Antminer S9 suitable for home mining?

Only with acoustic isolation: at ~76 dB it is data-center loud. Home miners use soundboxes, sheds, or pick a quiet unit like the Avalon Mini 3 or Bitaxe.

The longer story

The S9 mined an entire era — the 2016–2020 workhorse that at its peak WAS the network, and the best-selling ASIC ever made. Today its efficiency is hopeless on any normal power price, and its second life is heat: reflashed with open firmware, underclocked, warming greenhouses and garages that would burn the electricity anyway.

It suits heat-reuse projects, off-grid experiments and museum shelves. Buy one for what it is — a piece of working history and a 1.3 kW heater — never as a business.
