Bitmain Antminer S19j Pro (96Th) is an ASIC miner designed for SHA-256 algorithm, specifically targeting BTC (Bitcoin) . It delivers a maximum hashrate of 96Th/s while consuming 2832W of power, resulting in an energy efficiency of 0.03j/Gh.
Compact SHA-256 BTC Mining with Stable Air-Cooling
The Avalon Miner A1246 offers dependable SHA-256 performance for Bitcoin mining, achieving 90Th/s at 3420W. Designed by Canaan, this air-cooled ASIC miner balances energy efficiency with hardware simplicity, making it ideal for decentralized, rack-level, or small farm deployments. Its power efficiency is rated at 0.038j/Gh, allowing consistent operation while reducing long-term energy overhead.
Unlike hydro-cooled systems, the A1246 simplifies setup and maintenance through its built-in fan layout and direct airflow channeling. Moreover, its rugged metal housing supports secure placement in varied environmental conditions. Operators benefit from reduced upfront infrastructure requirements without sacrificing hash stability.
Versatile SHA-256 Hashing in a Self-Cooled Form
- 90Th/s SHA-256 hashrate for reliable BTC mining
- 3420W power use with 0.038j/Gh energy ratio
- Dual-fan air-cooling minimizes ambient heat risk
- Durable industrial design withstands field conditions
- Compatible with 19″ rack setups and solo deployments
The Avalon Miner A1246 runs smoothly across long operating cycles thanks to firmware-driven thermal monitoring and voltage balancing. Internal safety checks prevent overheating while optimizing chip-level workload distribution. These features contribute to its reputation for minimal downtime and high availability.
Additionally, the unit integrates easily into traditional mining environments without water loops or custom enclosures. Its straightforward design makes it a preferred choice for miners scaling up with limited infrastructure. For BTC operations that prioritize efficiency, reliability, and air-based cooling, the Avalon Miner A1246 remains a practical SHA-256 solution.
