Bitmain Antminer S21 XP Immersion 300 TH/s

Bitmain Antminer S21 XP Immersion (300 TH/s) – High-Efficiency SHA-256 Bitcoin Miner for Oil Immersion

Built for immersion farms: 300 TH/s at 13.5 J/TH

The Bitmain Antminer S21 XP Immersion is a fanless SHA-256 ASIC miner designed to run fully submerged in dielectric cooling oil. In Normal Energy Mode it delivers 300 TH/s at 4050 W (13.5 J/TH). In High Energy Mode it reaches 380 TH/s at 5700 W (15.0 J/TH) for operators who want more output per unit and have the power and cooling capacity for it.

With no fans, the S21 XP Immersion runs quietly and its hashboards are protected from dust and humidity. It mines Bitcoin (BTC), Bitcoin Cash (BCH) and Bitcoin SV (BSV) on any SHA-256 pool over standard Ethernet, which makes it a strong fit for immersion tanks, mining containers and hosted sites.

Technical Specifications

Why Choose the Antminer S21 XP Immersion?

13.5 J/TH efficiency – more hashrate per watt than the S21 Immersion (16 J/TH), so each terahash costs less electricity
Two power modes – 300 TH/s at 4050 W, or up to 380 TH/s at 5700 W when your power and cooling allow it
Fanless and quiet – no fans to wear out, no fan noise and no dust or humidity on the hashboards
Made for immersion infrastructure – lifting handles for the tank, standard 3-phase power input and Ethernet
Support from Mineshop.eu – warranty, after-sales help and tracked delivery

FAQs

Q: Can the S21 XP Immersion run with air cooling?
No. It has no fans and must be fully submerged in dielectric cooling oil, in an immersion tank with oil circulation and a heat exchanger or dry cooler.

Q: What power supply does it need?
A 3-phase 380–415 V AC supply at 50–60 Hz, rated for at least 12 A per unit. Plan for 4050 W per miner in normal mode and up to 5700 W in high energy mode.

Q: What oil temperature and flow does it need?
Bitmain specifies an inlet oil temperature of 20–50 °C and an oil flow of about 1 m³/h per unit. The hashrate and efficiency figures are rated at 30 °C inlet oil.

Q: What is the difference between normal and high energy mode?
Normal mode gives 300 TH/s at 4050 W (13.5 J/TH). High energy mode raises the hashrate to about 380 TH/s at 5700 W (15.0 J/TH), so it needs more power and more cooling capacity.

Q: Which coins can I mine with it?
Any SHA-256 coin, mainly Bitcoin (BTC), Bitcoin Cash (BCH) and Bitcoin SV (BSV), on the mining pool of your choice.
