The Bitcoin Miner S21 XP is built for miners seeking a balance between strong hashrate output, energy efficiency, and straightforward air-cooling deployment. With a typical hashrate of 270 TH/s and power consumption of 3,645W, this miner delivers dependable performance suitable for mining farms, hosting facilities, and dedicated mining rooms.
Its air-cooling system uses high-speed fans and optimized airflow to maintain stable operating temperatures, making it an accessible option for environments where liquid or hydro cooling is not available. Operating on single-phase power, the S21 XP integrates easily into existing electrical setups while maintaining consistent performance under continuous workloads.
Optimized for the SHA-256 algorithm, the miner supports BTC, BCH, and BSV, providing flexibility across multiple blockchain networks. The robust hardware design, Ethernet connectivity, and well-defined environmental tolerances make the Bitcoin Miner S21 XP a practical choice for experienced miners focused on reliability and scalability.
Actual mining performance may vary depending on ambient temperature, ventilation quality, power conditions, and network difficulty.
