The Bitcoin Miner U3S21EXPH is designed for large-scale and institutional mining operations that demand extreme hashrate density and reliable hydro-cooling performance. With a powerful 860 TH/s typical hashrate and 11,180W power draw, this miner is optimized for environments where high output, controlled cooling, and long-term uptime are essential.
Its hydro-cooling system enables precise temperature regulation across continuous workloads, helping reduce thermal stress and maintain stable performance. Compared to air-cooled solutions, liquid cooling supports quieter operation and higher efficiency in densely packed mining infrastructures when paired with proper cooling systems.
Optimized for the SHA-256 algorithm, the U3S21EXPH supports mining of BTC, BCH, and BSV, providing flexibility across major proof-of-work networks. Designed for three-phase power environments and high-capacity electrical setups, it integrates seamlessly into professional mining farms, hosting facilities, and containerized mining solutions.
Actual mining performance may vary depending on power quality, cooling configuration, environmental conditions, and network difficulty.
