Antminer S21+

The Bitmain Antminer S21+ is the newest generation of high-efficiency Bitcoin miners from Bitmain, engineered for professionals who demand maximum performance and long-term profitability. It delivers a powerful hashrate between 216 TH/s and 235 TH/s, with only 3564 W of power consumption, making it one of the most energy-efficient miners in its class. Built on Bitmain’s advanced SHA-256 chip architecture, the S21+ achieves an impressive energy efficiency of around 15 J/TH, allowing miners to reduce electricity costs while maintaining top-tier output. It’s designed to mine Bitcoin (BTC), Bitcoin Cash (BCH), and BSV, offering consistent performance across multiple SHA-256 coins. The Antminer S21+ features an upgraded air-cooling system with dual high-speed fans to ensure efficient heat dissipation. This prevents overheating and extends the machine’s operational lifespan, even under 24/7 workloads. The recommended environment is 0–40°C with 10–90% humidity for stable, continuous mining. Thanks to its strong aluminum alloy shell and optimized design, the S21+ combines durability with easy installation. It’s the ideal choice for hosting facilities or private farms looking to maximize mining performance with minimal downtime. With PSU included and Bitmain’s manufacturer warranty, the S21+ is ready for plug-and-play deployment in any serious mining operation.
