Antminer S21j XP Hyd.

$10,642.00

The Antminer S21j XP Hyd. is a high-performance SHA-256 miner engineered for industrial liquid-cooling environments. It delivers a formidable 495 TH/s hashrate with an ultra-efficient energy ratio of 12.0 J/TH. By consuming 5940W on a three-phase 380-415V input, this hydro-cooled unit minimizes thermal loss and operates significantly quieter than air-cooled alternatives (under 50 dB). Its robust liquid-circulation design ensures consistent performance and component longevity, making it a premier choice for institutional-grade facilities focused on maximizing long-term ROI.
