The Antminer S19k Pro has quickly become a favorite among professional miners due to its improved architectural design over the standard S19 Pro models. By using more efficient chipsets and a redesigned cooling path, the 115 TH/s variant provides the high hashrate needed to compete in the current Bitcoin (BTC) and Bitcoin Cash (BCH) network.

Optimized Energy Efficiency (23 J/TH)
Operating at approximately 2645W, the Antminer S19k Pro 115T maintains a highly sought-after efficiency ratio of 23 J/TH. This balance between high output and manageable power draw makes it particularly effective for mining operations looking to scale their Terahash-per-rack ratio without overloading their electrical infrastructure.
Advanced Cooling & Longevity
The S19k Pro series features Bitmain’s advanced thermal management system:
-
Enhanced Airflow: Four high-speed fans work in a push-pull configuration to ensure consistent intake and exhaust, preventing hot spots on the hash boards.
-
Firmware Stability: The pre-installed Bitmain firmware is optimized for the “k” series hardware, providing a stable hashrate with minimal fluctuations.
-
Rugged Build Quality: Designed for 24/7 operation in professional data centers, the chassis is built to withstand high-density environments.
