Overview
The Bitmain Antminer S21 XP Immersion is a purpose-built SHA-256 miner for facilities equipped with dielectric-fluid immersion cooling. This 300TH/s variant operates in Normal Energy Mode at a typical wall power of 4050W, providing a rated efficiency of 13.5J/TH at a 30°C inlet oil temperature.
Deployment requires 380–415V three-phase AC power, a 50–60Hz supply and an RJ45 Ethernet network connection. The specified maximum input current is 12A. Its cooling loop must maintain an inlet oil temperature of 20–50°C and approximately 1m³/h of oil flow, so tank, pump, heat-exchanger and coolant compatibility should be confirmed before installation.
The miner measures 364 × 236 × 293mm and weighs 16.8kg before packaging. Allow adequate tank clearance for the chassis and handle, and size electrical and heat-rejection infrastructure for continuous 4050W operation. Actual hashrate may vary by ±3%, while wall power and efficiency may vary by ±5% under the stated operating conditions.
This listing is for the 300TH/s Normal Energy Mode configuration. A separate High Energy Mode is documented for the platform, but its 380TH/s and 5700W ratings are not the specifications of the delivery option offered here.

Bitmain Antminer S21 XP Immersion 300TH/s FAQs
This is the 300TH/s Normal Energy Mode variant, rated at 4050W and 13.5J/TH with a 30°C inlet oil temperature. Typical hashrate may vary by ±3%, and wall power and efficiency may vary by ±5%.
No. It is designed for operation in a compatible dielectric-fluid immersion system. The tank, coolant, pump and external heat-rejection equipment must be selected and prepared for the installation.
Plan for 380–415V AC three-phase power at 50–60Hz. The specified maximum input current is 12A. A qualified electrician should confirm the circuit, protection, connectors and local compliance before energising the miner.
Maintain an inlet oil temperature between 20°C and 50°C and provide approximately 1m³/h of oil flow per miner. Confirm coolant compatibility and sufficient heat-exchanger capacity for a continuous 4050W thermal load.
The platform documentation describes a separate High Energy Mode rated at 380TH/s and 5700W. The purchasable variation on this page is the 300TH/s, 4050W Normal Energy Mode configuration; do not size its circuit or cooling system using mixed-mode specifications.
It runs the SHA-256 algorithm and is offered primarily for Bitcoin mining. It is also technically compatible with Bitcoin Cash and Bitcoin SV, subject to your chosen pool, firmware and network requirements.
