About the Bitmain Antminer S9
The Antminer S9 is a 2017-era industrial Bitcoin miner that has had a second life in the home solo mining community. New, it was a flagship; today, it's a well-understood, cheap secondhand device that people buy precisely because they want to solo mine at a meaningfully higher hashrate without paying new-unit prices. The S9 is aimed at the home miner who has the space, the airflow, and the electricity budget for industrial-class hardware — and who understands that efficiency numbers look very different on a 2017 chip than on a 2024 one.
At 14 TH/s and 1,372 watts, the S9 runs at roughly 98 J/TH — several times worse efficiency than a current-generation SHA-256 ASIC. That is the single most important fact about this device for a home miner. At $0.12/kWh, the S9 costs about $118 per month in electricity; at $0.20/kWh, closer to $200. Before committing to running one continuously, do the arithmetic against your actual rate. Many hobbyists run S9s happily on cheap power or during winter, when the heat output is useful; in a hot climate with expensive electricity, the math turns quickly.
The S9 is a SHA-256 miner, so it can point at Bitcoin, Bitcoin Cash, BSV, eCash, and other SHA-256 chains. At 14 TH/s, it has meaningfully better odds of landing a block on any given SHA-256 chain than a Bitaxe-class device. The live cross-coin ranking on the calculator ranks every supported SHA-256 coin by expected value for this exact hashrate, which is the number you actually want to optimize against. Because the S9's efficiency is weak relative to modern gear, the EV calculation on any given coin is particularly sensitive to your electricity rate — don't skip the cost field.
The S9 runs Bitmain's stock firmware or community replacements like Braiins OS. Most home miners use the stock web UI, point at a solo pool, and provide a payout address. It is loud — truly, industrially loud — and requires real airflow. Compared with a Bitaxe Gamma, an S9 is several orders of magnitude noisier and uses about ninety times the power for roughly ten times the hashrate. Before running one, make sure the room and circuit can handle it. SoloOdds Pro sends automatic EV-shift alerts for whichever SHA-256 coin is currently top-ranked, so the calculator doesn't need to be babysat.
