Description for: Bitmain Antminer S21j XP Hydro

BITMAIN · ANTMINER S21j XP HYDRO

Antminer S21j XP Hydro | 495 TH/s Bitcoin Miner

Liquid-Cooled Efficiency · 495 TH/s · 12 J/TH · 5940 W

Liquid / Hydro Cooled SHA-256 · BTC 12 J/TH Efficiency PSU Included

The Bitmain Antminer S21j XP Hydro, also known as the Antminer S21j XP Hyd, is one of the most efficient liquid-cooled Bitcoin (BTC) miners in the S21 series. It delivers a strong 495 TH/s hashrate at an industry-leading 12 J/TH efficiency, drawing 5940 W. A closed-loop hydro (liquid) cooling system puts the water-cooled plate in direct contact with the chips for efficient heat dissipation, enabling stable 24/7 operation, higher rack density, and lower noise than any air-cooled ASIC. Built for professional farms and hydro-cooling containers – and it ships with a compatible PSU.

Closed-Loop Hydro Cooling The water plate contacts the chip directly for efficient heat transfer and stable full-load running.	Industry-Leading 12 J/TH One of the most efficient Bitcoin miners ever produced – more BTC per watt.
Strong 495 TH/s Output High single-unit hash power for dense rack layouts and scalable farm deployment.	Reliable & Warrantied Built for continuous 24/7 industrial use and backed by a 365-day Bitmain factory warranty.

Worldwide Shipping & Deployment

Designed for the 380–415 V industrial power and coolant-circulation infrastructure used by mining farms across the USA, Canada, the European Union, the Middle East, Central Asia, Russia, Ethiopia, Paraguay, and beyond. With its closed-loop hydro cooling and 12 J/TH efficiency, the S21j XP Hydro is ideal for high-density data-center racks and hydro-cooling containers where heat, noise, and space are tightly managed. DDP shipping options available on request.

Frequently Asked Questions

Can I run the S21j XP Hydro at home?

It's built for industrial facilities, not typical homes. It needs a compatible external water-cooling loop, 380–415 V power, and proper coolant circulation (8–10 L/min).

Does it come with a power supply and cooling kit?

A PSU is included. The external hydro-cooling loop/kit is required for operation and may be supplied separately – confirm with our sales team when ordering.

Which coins can it mine?

It runs the SHA-256 algorithm, so it mines Bitcoin (BTC) and other SHA-256 coins such as Bitcoin Cash (BCH) and BSV. It supports both pool and solo mining.

Why is it so efficient?

At 12 J/TH, it's among the most efficient Bitcoin miners ever made. Closed-loop liquid cooling removes heat far better than fans, letting the chips run hard at lower energy cost per terahash.

What warranty and shipping do you offer?

New units come with Bitmain's 365-day factory warranty. We ship worldwide, with DDP options available on request – contact our sales team for rates and lead times.
