Bitmain Antminer S21e Hydro

Bitmain Antminer S21e Hydro – 332 TH/s SHA-256 Bitcoin Miner

The Bitmain Antminer S21e Hydro is a high-performance SHA-256 ASIC miner designed for efficient and powerful Bitcoin mining. Built with advanced hydro-cooling technology and optimized for the demanding SHA-256 algorithm, this miner delivers a substantial 332 TH/s hashrate while maintaining a competitive energy efficiency—making it a top choice for professional miners and large-scale operations.

Key Features

• Hashrate: 332 TH/s ±10% — strong performance for profitable BTC mining.

• Algorithm: SHA-256, ideal for mining Bitcoin (BTC), Bitcoin Cash (BCH) and other SHA-256-based coins.

• Hydro Cooling: Integrated liquid cooling system for thermal stability under high load.

• Power Consumption: ~5644 W — efficient power delivery for consistent hashing.

• Energy Efficiency: ~17 J/TH — excellent balance of power use and hashing output.

• Noise Level: ~50 dB (quiet for a hydro-cooled unit).

• Network: Ethernet interface for reliable connectivity.

• Compact Design: Designed for rackable deployment (typical industrial form factor).

Mining Performance & Use Cases

The Antminer S21e Hydro is engineered to excel in intensive mining environments with powerful hydro cooling that keeps hashboards operating efficiently at higher loads. Its 332 TH/s performance makes it suitable for professional Bitcoin farms, hosting facilities, or institutional setups where uptime and efficiency are critical.

Mineable Cryptocurrencies:

• Bitcoin (BTC)

• Bitcoin Cash (BCH)

• Other SHA-256-based coins

Mining yields will vary based on network difficulty, electricity costs, and cryptocurrency price movements.

Hydro Cooling Benefits

Hydro cooling provides more stable operating temperatures compared to traditional air-cooled systems, helping to:

Reduce thermal stress on components
Maintain consistent hashrate under load
Potentially extend hardware lifespan

This makes the S21e Hydro especially effective in dense mining racks or containers where airflow may be limited.
