Enter a new era of liquid cooling! The S21j XP Hyd from Bitmain mines the SHA-256 algorithm with a maximum hashrate of 495 Th/s for a power consumption of 5940 watt. The S21j XP Hyd comes with powersupply included.
The Bitmain Antminer S21 XP Hydro is the most powerful liquid-cooled Bitcoin miner in the Antminer S21 series. With a hashrate of 473 TH/s and an industry-leading power efficiency of just 12 J/TH, the Antminer S21 XP Hydro — also known as the Antminer S21 XP Hyd — outperforms every air-cooled ASIC on the market.
At Antminer Distribution Europe, we ship the Antminer S21 Hydro directly from the Netherlands, meaning no additional import duties or customs delays for EU customers. Every unit comes with the power supply included and up to two years of warranty, far exceeding the standard 180-day coverage from Bitmain.
Whether you are scaling up an existing mining farm or transitioning from air-cooled hardware to liquid cooling, the Bitmain Antminer S21 Hydro offers unmatched efficiency, hashrate, and reliability.
Why choose the Bitmain Antminer S21 XP Hydro?
The Antminer S21 XP Hydro delivers a transformational leap over air-cooled mining. Compared to the Antminer S21 (200 TH/s, 17.5 J/TH), the S21 XP Hyd produces 2.4× the hashrate while being 31% more power-efficient per terahash. Liquid cooling enables this by removing heat far more effectively than fans.
Running at 5,676W, the Antminer S21 Hyd consumes approximately €13.62 per day at €0.10/kWh. Despite the higher absolute wattage, the cost per terahash is significantly lower than any air-cooled model, making the S21 XP Hydro the preferred choice for operations optimising for maximum efficiency.
Liquid cooling does require an external water loop or hydro kit. Antminer Distribution offers the Lian Li hydro kit separately for customers who do not yet have a cooling infrastructure in place.
