Bitmain Antminer KS7 (45Th/s)

The Bitmain Antminer KS7 (45Th) is a specialized KHeavyHash ASIC miner engineered for Kaspa (KAS) mining, delivering a maximum hashrate of 45Th/s with exceptional energy efficiency. Released in January 2026, this dedicated mining platform achieves an efficiency rating of just 0.077j/Gh, making it a highly competitive option for miners focused on maximizing KHeavyHash performance. Built around Bitmain’s latest ASIC technology, the KS7 combines substantial computational power with optimized energy utilization to support efficient long-term mining operations. Its 430 x 196 x 290mm chassis, 16.4kg construction, and four-fan cooling system are designed to maintain stable performance under continuous workloads, while Ethernet connectivity ensures dependable network integration and consistent mining output.

For miners evaluating dedicated Kaspa hardware, the Antminer KS7 offers a compelling balance of performance, efficiency, and operational reliability. The unit operates on 220–277V power infrastructure and is engineered for uninterrupted mining environments where sustained hashrate is critical. With a noise level of 75dB, it is best suited for dedicated mining facilities or properly isolated installations. Support for operating temperatures between 5°C and 45°C and humidity levels from 10% to 90% provides deployment flexibility across a range of conditions. By combining a powerful 45Th/s hashrate with highly efficient energy consumption, the KS7 enables miners to optimize production potential while maintaining competitive operating costs within the rapidly growing Kaspa ecosystem.

KHeavyHash is a cryptographic hash function that serves as the backbone of Kaspa proof-of-work consensus mechanism. This algorithm processes input data of any length and produces a fixed hash value, ensuring security and integrity in the mining process.
