Optimized Power Efficiency: 11J/TH Performance
Despite its massive computational power, the Antminer S21 XP+ Hyd maintains an impressive energy efficiency of 11 joules per terahash (J/TH). This level of efficiency is critical for minimizing electricity costs—the single largest expense in mining operations.
With a total wall power draw of 5500W, proper energy planning remains essential. However, when paired with low-cost electricity sources—such as renewable energy or industrial-rate power—the S21 XP+ Hyd becomes exceptionally cost-effective over time.
This model operates on a 380–415V AC input, making it ideal for industrial environments and data centers where three-phase power is standard. Its optimized power supply reduces waste heat and improves overall system reliability.
Advanced Liquid Cooling System for Maximum Stability
One of the standout features of the S21 XP+ Hyd is its integrated liquid cooling system. Unlike traditional air-cooled miners that struggle with heat buildup in dense setups, this model uses direct-die liquid cooling to maintain optimal temperatures—even under continuous full-load operation.
Benefits include:
- Lower operating temperatures (ideal range: 20–50°C)
- Reduced thermal throttling, ensuring consistent hashrate
- Quieter operation at just 50dB, suitable for noise-sensitive environments
- Enhanced lifespan due to reduced component stress
Thanks to its superior thermal management, the Antminer S21 XP+ Hyd is perfectly suited for large-scale mining farms where heat accumulation can degrade performance and increase maintenance costs.
Compact Design and Easy Deployment
Despite its industrial-grade performance, the S21 XP+ Hyd boasts a surprisingly compact footprint:
- Dimensions: 339 x 173 x 207 mm
- Net weight: 13.8 kg
Its lightweight and space-efficient design make it easy to transport, install, and scale across multiple units. Whether you're deploying in a warehouse, container farm, or modular data center, this miner fits seamlessly into modern mining infrastructures.
Additionally, it supports RJ45 Ethernet (10/100M) connectivity for stable network integration, allowing remote monitoring and control via standard mining management platforms.
