Designed for maximum profitability in the post-halving era, the S21 225T utilizes Bitmain’s latest 5nm chip architecture to provide unmatched stability and performance. Order your Antminer S21 225T today at CryptoMiners24 and lead the race in SHA-256 mining efficiency.

The Antminer S21 series marks a revolutionary step forward in ASIC technology. While previous generations struggled to balance high hashrates with low power consumption, the S21 225 TH/s achieves both, making it the premier choice for professional mining farms and serious home operators alike. Optimized for Bitcoin (BTC), Bitcoin Cash (BCH), and Bitcoin SV (BSV), it is built to dominate the SHA-256 network.

Unmatched 15.0 J/T Efficiency

In modern crypto mining, the cost of electricity is the most significant factor in your ROI. The Antminer S21 225T operates at a power consumption of 3375W, achieving an industry-leading efficiency ratio of 15.0 J/T. This efficiency allows you to mine more Bitcoin for every watt consumed, protecting your margins against difficulty increases and market volatility.

Advanced Thermal Engineering

Despite its massive power, the S21 is built to stay cool under pressure. Bitmain has overhauled the internal architecture to include:

  • High-Flow Fan System: Four industrial-grade fans provide high-velocity airflow, ensuring that heat is moved away from the 5nm chips instantly.

  • Redesigned Heat Sinks: The cooling surface area has been increased to prevent thermal throttling, allowing for a consistent 225 TH/s output.

  • Environment Resilience: The S21 is designed to operate efficiently in temperatures up to 45°C, making it suitable for a wide range of climates.

  • New APW PSU: The integrated power supply is specifically tuned to handle the high-efficiency demands of the S21 hardware, ensuring electrical stability and safety.
