Antminer S21+ Hyd Description

The Antminer S21+ Hyd brings together leading-edge performance and industrial-grade build quality for SHA-256 Bitcoin mining. With a strong 319 TH/s hashrate and a 4785 W power draw, this miner is designed for operators seeking high BTC throughput without compromising on stability. The integrated hydro-cooling design significantly improves thermal management compared with air-cooled rigs — reducing heat stress, enabling denser rack deployment, and maintaining stable hash output under continuous 24/7 operation.

Applicants should run the S21 Hyd in facilities with proper coolant circulation, three-phase power supply, and controlled environments. With rack-mount design and standard AC input, integration into existing mining farms is straightforward when infrastructure is prepared. For miners scaling operations or building new farms, the S21 Hyd offers an excellent balance between raw hash rate and manageable cooling demands.

Algorithm	SHA-256 (BTC / BCH / BSV) SHA-256 (BTC / BCH / BSV)
Typical Hashrate	Up to ~335 TH/s (or close, depending cooling setup) ~234–234 TH/s (standard spec)
Cooling Method	Hydro-cooling (liquid / water-coolant system) Air-cooled (dual-fan standard ASIC cooling)
Power Consumption	Higher due to hydro setup + high hash → needs industrial-grade power & coolant circulation ~3510 W, suitable for standard power supply
Energy Efficiency (Hash per Watt)	Higher potential: liquid cooling enables stable high load and better thermal control, improving long-term efficiency per TH Balanced efficiency with standard power draw, simpler infrastructure needs
Infrastructure Requirement	Requires coolant tank or water-cooling system, stable multi-phase power, proper coolant circulation & maintenance Standard AC power input, basic ventilation, minimal extra infrastructure
Best For / Use Case	Large-scale / industrial mining farms, high-density rack deployment, long-term mining operations Small to medium farms or setups needing stable performance with simpler deployment
Advantages	Very high hashrate and throughput, excellent thermal stability under heavy load, suitable for dense mining racks or farms Easier to deploy, lower complexity, lower upfront infrastructure and maintenance needs
Considerations / Drawbacks	Requires substantial cooling infrastructure and stable power; higher setup and maintenance cost Lower maximum hashrate compared to hydro-cooled variant; standard air cooling may limit density in large farms

Notes

(1) The hashrate value, power on wall, and power efficiency on wall are all typical values. The actual hashrate value fluctuates by ±3%, and the actual power on wall and power efficiency on wall fluctuate by ±5%.
(2) Caution: Wrong input voltage may cause server damaged.
(3) The noise is loudest when the fan is under maximum RPM(rotation per minute).
(4) When the server is used at an altitude from 900m to 2000m, the highest operating temperature decreases by 1℃ for every increase of 300m.
