The Bitmain Antminer S21 XP+ Hyd (500Th/s) is Bitmain’s most powerful and efficient hydro-cooled Bitcoin ASIC miner, engineered for hyperscale and enterprise mining operations that demand maximum hashrate density and the lowest possible energy cost per terahash. Designed for the SHA-256 algorithm, this miner is purpose-built for Bitcoin (BTC) mining at the highest professional level.

Delivering an unprecedented 500 TH/s hashrate while consuming just 5500W, the S21 XP+ Hyd achieves a class-leading efficiency of 11 J/TH, setting a new benchmark for Bitcoin mining performance. Its advanced OD10 hydro-cooling system enables continuous peak operation, exceptional thermal stability, and extended hardware lifespan, even in high-density deployments.

Released in July 2025, the Antminer S21 XP+ Hyd represents the pinnacle of Bitmain’s S21 generation. Hydro cooling reduces operational noise to 50 dB, making it ideal for data centers, immersion-ready hydro facilities, and professional hosting environments with liquid-cooling infrastructure.

Operating on 380–415V power, the S21 XP+ Hyd is designed for industrial electrical setups and large-scale mining farms. With reliable Ethernet connectivity and robust engineering for 24/7 uptime, this miner is the definitive choice for operators seeking the highest performance per unit in the Bitcoin mining industry.
