The Bitmain Antminer S21 XP Immersion (300Th/s) is a next-generation immersion-cooled Bitcoin ASIC miner, engineered for elite performance, stability, and maximum operational efficiency. Designed for the SHA-256 algorithm, this miner is purpose-built for Bitcoin (BTC) mining in professional immersion and data-center environments.

Delivering an exceptional 300 TH/s hashrate at 4050W, the S21 XP Immersion maintains an industry-leading efficiency of 13.5 J/TH, making it one of the most powerful and efficient immersion-ready Bitcoin miners available. Immersion cooling dramatically reduces thermal stress, increases hardware lifespan, and enables quieter, more stable long-term operation compared to traditional air-cooled systems.

Released in September 2024, the S21 XP Immersion represents Bitmain’s latest ASIC architecture optimized for oil-based cooling systems. With a reduced noise level of just 50 dB, it is ideal for immersion farms, containerized mining deployments, and professional hosting facilities focused on density and efficiency.

The miner features standard Ethernet connectivity for seamless network integration and is built to operate continuously under heavy workloads. If you are scaling a professional immersion mining operation or upgrading to the most advanced Bitcoin hardware available, the Antminer S21 XP Immersion (300Th) delivers unmatched performance and reliability.
