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 500 TH/s (±3%) using the SHA-256 mining algorithm. This makes it one of the most powerful and efficient 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 5500W (±5%) of power. Combined with its 500 TH/s hashrate, this results in an industry-leading energy efficiency of 11 J/TH, making it the most efficient hydro-cooled Bitcoin miner available in 2025.
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 with maximum efficiency.
Hydro-cooling provides superior thermal management compared to air cooling. The closed-loop liquid cooling system (OD10) 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's designed for professional mining operations with proper three-phase power infrastructure for optimal operation and efficiency.
The S21 XP+ Hyd features compact dimensions of 339 x 173 x 207mm and weighs just 14.2 kg, making it lighter and more portable than previous generation hydro-cooled miners. This compact design facilitates easier transportation, deployment, and maintenance in mining facilities.
The S21 XP+ Hyd's 500 TH/s hashrate combined with best-in-class 11 J/TH efficiency makes it the most profitable hydro-cooled Bitcoin miner available. Based on current network conditions at $0.07/kWh electricity costs, it can generate approximately $10-20 daily depending on Bitcoin prices. With lower electricity rates ($0.045/kWh), miners can retain over 75% of revenue as net profit.
