Antminer S21 200T – Efficient SHA-256 Mining for Professional Bitcoin Operations
The Antminer S21 200T by Bitmain is a next-generation ASIC miner designed for SHA-256 cryptocurrencies, including Bitcoin (BTC), Bitcoin Cash (BCH), and Bitcoin SV (BSV). Built for professional miners and industrial-scale deployments, this model combines strong hashrate performance, dependable stability, and improved energy efficiency for long-term mining operations.
With a hashrate of 200 TH/s, power consumption of 3500 W @25°C, and energy efficiency of 17.5 J/TH, the S21 200T offers a strong balance between mining output and operating cost. It is well suited for operators who want competitive SHA-256 performance while maintaining stable 24/7 operation in demanding mining environments.
Built for Stable 24/7 Mining
The Antminer S21 200T is designed for continuous operation with a proven air-cooled architecture and standard Ethernet connectivity. Retail listings consistently position it as a professional-grade miner for dedicated mining farms rather than residential use, and current seller listings commonly describe it with industrial fan cooling and noise around 75 dB. The noise figure comes from reseller listings rather than the Bitmain support page, so it is best treated as typical market-listed data rather than the primary official spec.
