Antminer S23 questions
How much electricity does the Antminer S23 use?
The Antminer S23 draws 3,355 W at the wall (±5%). Running continuously that is about 80.5 kWh per day and 2,416 kWh per 30 days. Multiply by your electricity price to get the running cost, or use the calculator.
What is the hashrate and efficiency of the Antminer S23?
Rated hashrate is 305 TH/s (±3%) at 11 J/TH. Lower J/TH means less energy per unit of hashrate. See Understanding J/TH.
What voltage does the Antminer S23 need?
Input voltage is 220–277 V AC, single-phase at 50-60 Hz. It cannot run on a 110–120 V household circuit. Confirm your supply, breaker and cabling with a qualified electrician before ordering. See Bitcoin miner power requirements.
How is the Antminer S23 cooled?
The Antminer S23 is air-cooled with built-in fans. It needs a steady supply of cool intake air and a path to exhaust hot air. Rated noise is 76 dB. Compare options in Air vs hydro Bitcoin miners.
How loud is the Antminer S23?
The manufacturer rates it at 76 dB. That is industrial-level noise and unsuitable for a living space without a dedicated, sound-treated enclosure.
Can I order the Antminer S23 in bulk?
Yes. Orders are handled by quantity: small quantities through checkout when a price is published, and larger quantities by quotation with pricing, batch and logistics confirmed by sales. Request a wholesale quote.
