The S21j XP Hydro is Bitmain's Japan-market variant of the S21 XP Hydro, delivering 460 TH/s at 12.0 J/TH (derating range: 460–495 TH/s depending on coolant temperature). Drawing 5520W with hydro cooling, its 12.0 J/TH is among the most efficient figures available in a hydro-cooled Bitcoin miner. Liquid cooling enables quiet operation suitable for residential or noise-restricted environments. Requires dedicated water infrastructure and coolant management, and is optimized for Japanese power standards.
Key Features
- Industry-leading 12.0 J/TH energy efficiency
- Powerful 460 TH/s hashrate for maximum profitability
- Advanced thermal management with Hydro Cooling
- Easy setup and management via web interface
