The Antminer S21 XP+ Hydro represents the gold standard of Bitmain’s 2025 engineering. By moving the hashrate ceiling to 500 TH/s, Bitmain has effectively doubled the output of previous generation flagship miners while drastically reducing the energy required per terahash. This unit is designed specifically for 3-phase industrial environments and liquid-cooled data centers.
Unparalleled 11 J/TH Efficiency
The “XP Plus” designation signifies the highest binning of Bitmain’s latest generation chips. With an energy ratio of 11 J/TH, the S21 XP+ Hyd is the most profitable asset in a high-difficulty environment. At a sustained 5500W consumption, it provides more hashing power per dollar of electricity than any air-cooled or immersion alternative on the market.
Advanced Hydro-Cooling Architecture
The S21 XP+ Hyd is built to operate in high-density rack configurations (such as the Antrack V2):
-
Thermal Consistency: Liquid cooling eliminates the “heat soak” common in air-cooled units, ensuring that all chips perform at their peak frequency without throttling.
-
Silent Industrial Mining: Operating at approximately 50 dB, the water-cooled system is significantly quieter than fan-based miners, reducing the acoustic footprint of your facility.
-
Longevity: By maintaining a lower and more stable internal temperature, the hydro system extends the lifespan of the ASIC chips and reduces the failure rate of the internal components.
