Antminer KS5 Pro Description
The Antminer KS5 Pro is Bitmain’s advanced ASIC miner for the kHeavyHash algorithm, engineered specifically for Kaspa (KAS) and other emerging kHeavyHash-based cryptocurrencies. With a hashrate of 21TH/s and a power draw of 3150W, it provides a balanced combination of performance and efficiency. Its energy profile of approximately 150 J/TH positions it as a strong option for miners expanding long-term kHeavyHash operations.
The KS5 Pro features an industrial-grade air-cooled design capable of continuous, stable performance. Successful deployment requires proper airflow and a 220–277V power source, making it ideal for structured mining facilities or dedicated mining rooms. Noise output is comparable to other high-power ASIC miners and should be considered in installation planning.
Antminer KS5 Pro vs KS7
The Antminer KS7 delivers nearly double the hashrate of the KS5 Pro with far better efficiency, making it ideal for large-scale Kaspa mining. The KS5 Pro offers lower power demands and a more accessible entry point, suitable for smaller facilities or miners seeking stable performance without high electrical requirements.
Choose KS7 if:
You want the highest hashrate, best efficiency, and the strongest long-term performance for Kaspa mining. It is the superior model for farms scaling toward large deployments.
Choose KS5 Pro if:
You want a balanced, lower-barrier entry miner with moderate power needs and reliable output, suitable for smaller locations or early-stage expansion.
