Bitmain Antminer S21e XP U3 860T – Extreme-Performance Hydro Bitcoin Miner

The Bitmain Antminer S21e XP U3 860T is an ultra-high-performance, hydro-cooled SHA-256 ASIC miner designed for serious, large-scale Bitcoin (BTC) and Bitcoin Cash (BCH) operations. With up to 860 TH/s of hashrate and a high-density liquid-cooled design, it’s built for operators who want maximum hashpower per unit in professional mining or hosting environments.

By combining advanced chip design with a robust hydro-cooling system, the S21e XP U3 860T delivers exceptional performance while keeping temperatures under tight control. It’s ideal for containers, professional farms and data-centre style facilities that already have three-phase power and industrial cooling infrastructure in place.

What the Bitmain Antminer S21e XP U3 860T mines

• Algorithm: SHA-256

• Primary coins:

  • Bitcoin (BTC)

  • Bitcoin Cash (BCH)

• Other SHA-256 coins (pool dependent):

  • Bitcoin SV (BSV) and other SHA-256–based altcoins

Hashrate can be pointed at any SHA-256–based chain supported by your mining pool, although most operators will focus this class of hardware on BTC as the primary revenue source.

Key features

• Massive 860 TH/s SHA-256 hashrate
  Provides up to 860 terahash per second from a single hydro-cooled unit, making it a powerhouse option for high-density deployments and serious scaling.

• High efficiency for its class
  Despite the extreme hashrate, the S21e XP U3 860T is engineered for competitive energy efficiency in its tier, helping you get more hashrate from each kilowatt of power in environments with suitable electricity costs.

• Hydro cooling for maximum stability
  The integrated hydro-cooling system circulates coolant through the miner’s thermal channels, keeping chips within an optimal temperature band and reducing the thermal stress and dust issues common in air-cooled rigs.

• Lower noise footprint than air-cooled ASICs
  Thanks to liquid cooling, the typical noise level is far lower than a comparable air-cooled farm of equivalent hashrate. It still belongs in a dedicated mining or hosting environment, but the reduced fan noise simplifies acoustic management.

• Built for industrial 24/7 operation
  The S21e XP U3 860T is designed for continuous, round-the-clock mining when paired with a correctly designed hydro-cooling loop and three-phase power. It’s aimed squarely at professional and institutional mining operations.

• Standard Ethernet networking
  Configuration is straightforward: connect via RJ45 Ethernet, access the web interface, add your pools and wallet details, tune your operating profile, and start hashing.
