Antminer S23 Hyd 3U: Specifications and Installation Guide

The Antminer S23 Hyd 3U is a rack-format, liquid-cooled SHA-256 ASIC. This guide covers Bitmain’s U3S23H 1160T-10 specification. Before buying, match the exact model and batch to your electrical installation, cooling system and operating budget.

Manufacturer specifications for the 1,160 TH/s model

• Typical hashrate: 1,160 TH/s, with a stated ±3% variation.
• Typical power: 11,020 W at 35°C coolant inlet temperature; stated power variation ±5%.
• Typical efficiency: 9.5 J/TH, with a stated ±5% variation.
• Supply: three-phase 380–415 V AC, 50–60 Hz; maximum input current 24 A.
• Dimensions: 900 × 482.6 × 130 mm without packaging; net weight 42 kg.
• Network: Ethernet 10/100M.

Coolant requirements: check the inlet, not just room temperature

The manual specifies a 20–50°C coolant inlet range, 16–20 L/min flow and pressure no higher than 3.5 bar. These are miner requirements, not a complete cooling-system design. The previous version of this guide incorrectly listed 5–40°C as the coolant inlet range.

The external loop must circulate compatible coolant and reject the heat from the full installation. Check the manual’s fluid and water-quality requirements, fittings and control provisions. Include pumps and heat-rejection equipment when estimating auxiliary electricity use and maintenance. Liquid cooling does not make the complete installation silent.

Does any Antminer hydro rack fit the 3U model?

No. Verify rack depth, load capacity, chassis format and connections against the exact miner. A rack intended for Antminer shoe-box units is not automatically suitable for this 3U chassis. Likewise, do not apply the hashrate, power or cooling limits of a different S23 variant to this model.

Estimate installation and operating costs separately

At its typical 11.02 kW draw, one miner running for 24 hours uses approximately 264.48 kWh, before cooling auxiliaries and other losses. Multiply the actual measured consumption by your applicable electricity rate, then account for any demand charges, cooling, maintenance and service fees.

This energy calculation is not a revenue forecast. Network difficulty, Bitcoin price, pool fees, uptime and operating costs affect the outcome. Compare written equipment and hosting proposals using the same assumptions.

Checklist before an equipment or hosting quote

• Exact miner model, batch and quantity.
• Available three-phase supply and installation capacity, confirmed by a qualified electrician.
• Cooling-loop capacity, inlet conditions and heat rejection.
• Rack layout, access for maintenance and network connection.
• Equipment, installation and recurring service costs shown separately.

Compare purchase and hosting options

See the S23 Hyd 3U product listing for the configuration currently presented by CaptainMining. For a hosted installation, review hydro ASIC hosting and request confirmation that the model and quantity can be accommodated.
