120 TH/s of Bitcoin Hashrate. 23 J/TH Efficiency. Serious Mining.
The Bitmain Antminer S19K Pro is one of the most efficient miners in Bitmain's S19 generation — powered by the BM1366 5nm ASIC chip, it delivers a rock-solid 120 TH/s at just 23 J/TH, roughly 22% more efficient than the older S19j Pro. Released in April 2023, the S19K Pro has become the go-to mid-tier Bitcoin miner for both small farm operators and serious home miners with a dedicated 240V circuit, offering next-generation efficiency at a price well below the S21 flagship line.

Important — power requirements
This miner requires a dedicated 200–240V AC circuit. It is NOT compatible with standard 110V household power. Australian 240V power is compatible, but the S19K Pro needs a dedicated 15A circuit separate from your household circuits. Most home garages and workshops have a suitable 240V outlet. If unsure, consult a licensed electrician before purchasing.
Why the BM1366 chip matters
The BM1366 is Bitmain's 5nm ASIC chip — the same generation used in the S19 XP. At 23 J/TH, the S19K Pro sits in the "highly competitive" efficiency bracket, consuming roughly the same electricity per terahash as many far more expensive machines. Older S19j Pro units ran at 29.5 J/TH — the S19K Pro beats that by 22%, meaning lower electricity costs and better margins at every electricity price point.

Bitcoin mining profitability depends on network difficulty, BTC price, electricity costs, and other market variables. MinerHub does not guarantee mining returns. All hashrate, power, and efficiency figures are manufacturer-stated typical values (±3–5%). Electrical installation: this miner requires a dedicated 200–240V AC circuit — consult a licensed Australian electrician if needed. 75 dB noise output requires suitable ventilated space away from living areas.
