The world of cryptocurrency mining is evolving rapidly, and staying ahead requires cutting-edge technology, superior efficiency, and reliable performance. Enter the Bitmain Antminer S21 XP+ Hyd 500Th with PSU — a next-generation mining rig engineered for maximum output and minimal operational friction. Designed for serious miners aiming to optimize their hash power and energy efficiency, this hydro-cooled powerhouse represents the latest leap forward in Bitcoin mining hardware.
As part of Bitmain’s renowned Antminer series, the S21 XP+ Hyd integrates advanced hydro cooling, an integrated power supply unit (PSU), and an industry-leading 500 terahashes per second (Th/s) hash rate. Whether you're scaling up an existing mining farm or launching a new operation, this device delivers the performance, durability, and efficiency needed to thrive in today’s competitive mining landscape.
Unmatched Hash Rate and Power Efficiency
At the heart of the Antminer S21 XP+ Hyd lies its exceptional 500Th/s hash rate, positioning it among the most powerful ASIC miners available. This level of computational power enables faster block validation and higher potential rewards in Bitcoin mining. Paired with a total power consumption of 5,500 watts, the miner achieves an impressive energy efficiency ratio of 11 joules per terahash (J/TH) — a critical metric for reducing electricity costs and maximizing profitability.
With rising energy costs and increasing network difficulty, efficiency is no longer optional — it's essential. The S21 XP+ Hyd meets this demand head-on, offering one of the best performance-to-power ratios on the market for large-scale mining operations.

Advanced Hydro Cooling Technology
Unlike traditional air-cooled models that generate excessive noise and require extensive ventilation, the Antminer S21 XP+ Hyd features hydro cooling (OD10) technology. This innovative system uses liquid-based heat dissipation to maintain optimal operating temperatures even under continuous heavy loads.
Hydro cooling offers several key advantages:
- Reduced noise levels — operating at just 50dB, making it significantly quieter than standard models.
- Improved thermal management — maintains stable performance in environments with ambient temperatures between 20°C and 50°C.
- Higher density deployment — allows more units to be installed in confined spaces without overheating risks.
This makes the S21 XP+ Hyd ideal for industrial-scale mining farms where space, temperature control, and noise reduction are top priorities.
Compact Design and Industrial-Grade Build
Despite its immense power, the Antminer S21 XP+ Hyd boasts a surprisingly compact footprint measuring 339 x 173 x 207mm and weighing 13.8kg. Its sleek design allows for efficient rack mounting and seamless integration into existing data center infrastructures.
Built for durability, the unit supports humidity levels from 10% to 90% and operates reliably across a wide voltage range of 380–415V, ensuring consistent performance even in less-than-ideal environmental conditions.
Complete Out-of-the-Box Solution
One of the standout features of this model is the inclusion of a fully integrated power supply unit (PSU). This eliminates the need for sourcing compatible external PSUs, simplifying setup and reducing compatibility issues. The plug-and-play readiness reduces deployment time and ensures a smoother onboarding experience — especially valuable for operators managing hundreds or thousands of units.
Additionally, connectivity is handled via a standard Ethernet interface, enabling easy network integration and remote monitoring through Bitmain’s mining management software.
Reliability You Can Trust
Backed by a 6-month manufacturer warranty, the Bitmain Antminer S21 XP+ Hyd offers peace of mind for both individual investors and enterprise operators. While the warranty period may seem limited compared to some consumer electronics, it aligns with industry standards for industrial mining equipment, reflecting confidence in build quality and expected uptime.
For long-term operations, many miners pair this device with proactive maintenance plans and environmental monitoring systems to extend lifespan and sustain peak efficiency.
