Specifically, this powerhouse delivers a massive 234 TH/s hashrate while maintaining peak electrical efficiency. It utilizes advanced 5nm chip technology to optimize every single hash for maximum output. Consequently, serious miners choose this hardware to stay competitive in the evolving crypto landscape today.
Furthermore, this S21 Pro mining device operates with a optimized power consumption of 3510W. Bitmain designed this unit specifically for high-density mining farms and demanding industrial environments. The robust air-cooling system ensures consistent performance even during intensive continuous operations. Therefore, you can rely on this hardware for stable long-term mining results and high uptimes.
Antminer S21 Pro Bitcoin Miner Features and Benefits
The Antminer S21 Pro Bitcoin Miner features four high-speed fans for superior thermal management. Significantly, these fans circulate air through the chassis to keep the 5nm chips cool. Because temperature stays low, the device maintains its 234 TH/s throughput without thermal throttling. This cooling efficiency directly improves the lifespan of your expensive mining hardware components remarkably.
Similarly, this Bitmain SHA-256 miner offers an industry-leading efficiency rating of 15.0 J/TH. This low energy ratio allows operators to maximize their profit margins per terahash. The unit supports BTC, BCH, and BSV mining on the reliable SHA-256 algorithm. However, you must provide a stable 220V to 277V AC voltage for optimal performance.
