Antminer S19k Pro (120TH/s) – Air-Cooled Bitcoin Miner

Antminer S19k Pro (120TH/s) is the cost-optimised member of the S19 family — 23 J/TH at the lowest entry price in the generation.

Antminer S19k Pro Overview

The Antminer S19k Pro is an instructive chapter in Bitmain’s strategy. It appeared when the market wanted something between “old and inefficient” and “new and expensive”. Rather than chase performance, Bitmain redesigned the product around manufacturing cost — fewer components, simpler boards, lower unit price. Consequently, and somewhat ironically, it outperforms the original S19 Pro on efficiency while costing less.

⚠️ Buyer Considerations

• At ~23 J/TH it works comfortably on power under roughly $0.10/kWh.
• Worth comparing directly against the Antminer S19 XP (140Th): more hashrate and ~21.5 J/TH for about $380 more, which typically pays back inside a year on expensive electricity.
• 2,760 W requires a dedicated circuit — it will not run on a standard UK 13 A socket or Australian 10 A GPO.
• Noise (~75 dB) requires a garage, shed, outbuilding or hosting facility.
