Bitmain Antminer S19j Pro (100Th) is an ASIC miner designed for SHA-256 algorithm, specifically targeting BTC (Bitcoin) . It delivers a maximum hashrate of 100Th/s while consuming 3050W of power, resulting in an energy efficiency of 30.5j/Th.
SHA-256 Mining Machine Optimized for Steady Output
Bitmain Antminer S19 is a well-established ASIC miner built for SHA-256 mining algorithms. It delivers a hashrate of 95 terahashes per second, offering a steady balance between speed and efficiency. With a 3250W power draw and an energy efficiency rating of 0.034 J/Gh, this model supports long-duration operations in facilities focused on predictable performance.
Many operators value the S19 for its consistent thermal behavior and proven reliability across thousands of deployments. Since the model avoids unstable power spikes, it maintains output across day-long sessions without sudden drops in hash rate. This also reduces the risk of thermal throttling under high load conditions.
