Product Details

Bitmain Antminer S23 318TH Air-Cooled SHA-256 Bitcoin Miner for Professional Mining

318 TH/s of SHA 256 hashrate at 3,498W with air cooling. The Antminer S23 is Bitmain's current generation air cooled Bitcoin miner, running the same chip architecture as the S23 Hydro and S23 Immersion models at 11.0 J/TH efficiency.

220 to 277V single phase input makes the S23 compatible with standard industrial power without requiring three phase electrical. At 3,498W, a single 20A 240V circuit handles one unit comfortably. This matters for smaller operations and facilities scaling gradually where three phase service is unavailable or cost prohibitive.

75 dB air cooling means dedicated mining space with proper ventilation. Each unit produces approximately 11,900 BTU per hour of heat. Plan exhaust capacity accordingly, especially when deploying multiple units in enclosed spaces. 449 x 219 x 293mm at 15.8 kg.

Compared to the S23 Hydro (580 TH/s, 9.5 J/TH), the air cooled S23 trades efficiency and density for infrastructure simplicity. No water loops, no plumbing, no fluid management. Plug in power and Ethernet and start mining. For operations where cooling infrastructure cost matters more than per terahash efficiency, the air model makes the economics work. Mines Bitcoin, Bitcoin Cash, and all SHA 256 coins. Operates from 5 to 45 degrees Celsius.

Firmware management through Bitmain's web interface on your local network. Configure up to three pool addresses, monitor real time hashrate, and adjust power settings. Compatible with third party firmware like Braiins OS for additional tuning and optimization beyond stock settings.

Antminer S23 318TH Bitcoin Miner with 11 J/TH Efficiency

318 TH/s SHA 256 at 3,498W with air cooling. 11.0 J/TH efficiency on Bitmain's current S23 chip architecture. 220 to 277V single phase, no three phase required.

The simplest deployment path in the S23 family. No water loops, no immersion tanks, no dielectric fluid. Power and Ethernet. 75 dB at 449 x 219 x 293mm and 15.8 kg.

Produces approximately 11,900 BTU per hour. Plan ventilation and exhaust capacity before deploying in enclosed rooms. For operators who want current gen Bitmain silicon without liquid cooling investment, the air cooled S23 delivers at 11.0 J/TH. Mines Bitcoin, Bitcoin Cash, and all SHA 256 coins. 5 to 45 degrees Celsius operating range.

Bitmain web management interface for pool configuration and hashrate monitoring on your local network. Compatible with third party firmware for additional optimization. The S23 shares its chip architecture with the Hydro and Immersion variants, so firmware improvements to the S23 family benefit all models.

Antminer S23 318TH Bitcoin ASIC Miner

318 TH/s air cooled SHA 256 at 3,498W and 11.0 J/TH. Current gen Bitmain silicon on 220 to 277V single phase. No liquid infrastructure needed. 75 dB at 15.8 kg. The most straightforward deployment in the S23 series. Plug in power, connect Ethernet, and mine. 5 to 45 degrees Celsius operating range. Approximately 11,900 BTU per hour of heat output. Plan ventilation before deployment. Mines Bitcoin, Bitcoin Cash, and all SHA 256 coins. Compatible with third party firmware.

318TH Next Generation Hashrate

Bitmain's latest 5nm ASIC chips deliver 318 terahash of SHA-256 power, producing more Bitcoin per unit of electricity than any previous air-cooled Antminer.

11 J/TH Energy Efficiency

A major efficiency leap over the S21 series, the S23 reduces operating costs per terahash and compresses payback timelines in competitive mining environments.

Frequently Asked Questions

318 TH/s of SHA-256 at 3,498W — efficiency of 11 J/TH. The air-cooled flagship of the S23 generation, sitting between the S21 XP (13.5 J/TH) and S23 Hydro (9.5 J/TH) in efficiency.

The S23 delivers 318 TH/s at 11 J/TH vs the S21 XP at 270 TH/s and 13.5 J/TH. The S23 is 18% more efficient and 18% more hashrate — a clear generational improvement. Worth the premium for long-term operations.

With 11 J/TH efficiency, the S23 has strong profitability margins. Exact daily earnings depend on BTC price and network difficulty — use the live profitability calculator on this page for current numbers at your electricity rate. MillionMiner offers hosting from $0.055/kWh.

The S23 Hydro delivers 580 TH/s at 9.5 J/TH with liquid cooling. The air-cooled S23 at 318 TH/s and 11 J/TH requires no cooling infrastructure — plug and play. Choose the S23 for simplicity, S23 Hydro for maximum efficiency.

All SHA-256 cryptocurrencies: Bitcoin (BTC), Bitcoin Cash (BCH), BSV, eCash (XEC).

Approximately 75 dB. Requires dedicated mining space or professional hosting. MillionMiner offers hosting from $0.055/kWh.

Yes. Free worldwide DDP shipping to 50+ countries with all customs included. Genuine Bitmain hardware with manufacturer warranty.

At 11 J/TH, the S23 is among the most efficient air-cooled miners available. It represents a significant upgrade path from S21-series hardware for operators wanting better efficiency without hydro cooling infrastructure.

Integrated PSU accepting 200-240V AC. No external power supply required. Needs a 20A circuit.

At $0.07/kWh and current BTC prices, ROI depends on acquisition cost. With 2026 BTC price appreciation to $150K+, ROI accelerates significantly.
