Antminer S19k PRO Overview

The Antminer S19k PRO delivers high efficiency and strong profitability, making it a top choice for miners of all levels. With a 120 TH/s hashrate and 23 J/TH efficiency, it maximizes Bitcoin mining returns while keeping electricity costs low.

It supports SHA-256 coins like Bitcoin (BTC) and Bitcoin Cash (BCH), offering flexibility as network difficulty changes. The compact design (400mm x 195mm x 290mm, 12.8 kg) makes it easy to store and stack, perfect for scaling up mining operations.

Profitability? At BTC $50,000, daily earnings range $8–$15 depending on electricity costs. If BTC hits $80,000+, profits could double. But with electricity over $0.12/kWh, margins shrink. Cheap power is key.

This miner runs hot (~75dB noise), so proper cooling is a must. A well-ventilated space like a garage, basement, or mining farm works best. Regular maintenance — cleaning fans every few weeks — keeps it efficient.

Compared to newer models like the Antminer S19 XP (140 TH/s, 21.5 J/TH), it’s slightly less powerful but remains one of the best price-to-performance miners in 2025.

Final verdict: If you have access to electricity under $0.08/kWh, the S19k PRO is a solid long-term investment, balancing power, efficiency, and cost.
