Antminer S21 XP Hyd FAQ

Everything you need to know about the Bitmain Antminer S21 XP Hyd hydro-cooled Bitcoin miner.

The Bitmain Antminer S21 XP Hyd delivers a maximum hashrate of 473 TH/s (±3%) using the SHA-256 mining algorithm. This makes it one of the most powerful Bitcoin ASIC miners available, ideal for large-scale mining operations mining Bitcoin (BTC) and other SHA-256 cryptocurrencies.
The Antminer S21 XP Hyd consumes approximately 5676W (±5%) of power. Combined with its 473 TH/s hashrate, this results in an industry-leading energy efficiency of 12 J/TH, significantly more efficient than air-cooled alternatives and previous generation miners.
The Antminer S21 XP Hyd uses the SHA-256 algorithm, allowing you to mine Bitcoin (BTC), Bitcoin Cash (BCH), Bitcoin SV (BSV), and other SHA-256-based cryptocurrencies. It's optimized specifically for Bitcoin mining at industrial scale.
Hydro-cooling provides superior thermal management compared to air cooling. The closed-loop liquid cooling system makes direct contact with ASIC chips, resulting in whisper-quiet operation (50 dB vs 70+ dB), more consistent performance, extended hardware lifespan, and the ability to operate in higher density data center configurations with better heat dissipation efficiency.
The Antminer S21 XP Hyd requires a three-phase 380-415V AC power supply, making it suitable for industrial and data center environments. It has a maximum current draw of 12A per phase and requires proper three-phase power infrastructure for optimal operation.
The S21 XP Hyd uses a closed-loop hydro-cooling system. The inlet water temperature must be above 20°C for the miner to start. The system requires periodic monitoring of water conductivity - if conductivity reaches ≥100 μs/cm, the coolant must be replaced. Refer to the ANTSPACE HK3 Water Cooling Container manual for detailed maintenance instructions.
The S21 XP Hyd's 473 TH/s hashrate combined with 12 J/TH efficiency makes it one of the most profitable Bitcoin miners available. Based on current network conditions at $0.07/kWh electricity costs, it can generate approximately $9-15 daily depending on Bitcoin prices. The estimated ROI period is typically 14-20 months. Check the live profitability calculator above for real-time revenue estimates based on current market conditions and your specific electricity costs.
