Bitmain Antminer S21j XP Hyd Bitcoin Miner 495Th/s 5940W Hydro-cooling

Bitmain Antminer S21j XP Hyd (495Th): Industrial-Grade Hydro-Cooled Bitcoin Miner
The Pinnacle of SHA-256 Mining Performance
The Bitmain Antminer S21j XP Hyd (495Th) represents the absolute forefront of Bitcoin mining technology. Engineered for the SHA-256 algorithm and purpose-built for BTC (Bitcoin) , this hydro-cooled powerhouse delivers unprecedented hashrate with remarkable efficiency—setting a new standard for industrial-scale mining operations.
Antminer S21j XP Hyd Redefines Bitcoin Mining
⚡️ Massive 495 TH/s Hashrate
With a staggering 495 TH/s, the S21j XP Hyd delivers computational power that was unimaginable just years ago. This isn’t just an incremental upgrade—it’s a quantum leap forward. Whether you’re expanding an existing mining farm or building a new facility, every terahash translates directly to greater Bitcoin earning potential.
🔋 Exceptional 12 J/TH Efficiency
In Bitcoin mining, efficiency is profitability. The S21j XP Hyd achieves an outstanding 12 J/TH, consuming just 5940W to deliver its massive hashrate. This represents a significant efficiency gain over previous generations, dramatically reducing your electricity costs per Bitcoin mined. Lower operational overhead means higher margins, even during market fluctuations.
💧 Advanced Hydro-Cooling Technology
Unlike traditional air-cooled miners, the S21j XP Hyd leverages state-of-the-art hydro-cooling to maintain optimal operating temperatures. This sophisticated cooling system delivers multiple competitive advantages:


Sustained Peak Performance – No thermal throttling, even under maximum load


Ultra-Quiet Operation at 50dB – Perfect for noise-sensitive environments


Extended Hardware Lifespan – Reduced thermal stress on critical components


Higher Density Deployment – Pack more hashrate into your facility


Lower Facility Cooling Costs – Reject heat directly through liquid cooling infrastructure
