SHA256 ASIC miner at 120 TH/s

This Bitmain S19k Pro unit delivers a nominal hashrate of 120 TH/s with a tolerance of ±3% for SHA256-based coins such as BTC, BCH and BSV. It draws 2760 W ±5% at the wall and achieves a power efficiency of 23 J/TH ±5% at 25°C. The device is sold new and includes an integrated power supply but no power cord.

Suited for 200–240 V sites with adequate cooling

Operators with access to 200–240 V AC, 47–63 Hz circuits rated for at least 20 A can run this miner in ambient temperatures from 0°C to 45°C and humidity of 10–90% non-condensing. It is not suitable for 110 V supplies or locations above 2000 m altitude. Buyers unwilling to accept a 40% restocking fee on non-defective returns should consider other options.

Efficiency of 23 J/TH at 25°C

The single figure that determines suitability is the quoted wall-power efficiency of 23 J/TH ±5% measured at 25°C. If your electricity cost and cooling capacity make this efficiency viable, the miner matches the specification; otherwise a different device will be required.

Questions about this item

Will this miner run on a standard 120 V household outlet?

No. The power supply requires 200–240 V AC at 47–63 Hz and draws up to 20 A. A 120 V circuit cannot power the unit.

What size breaker and wiring do I need for the 20 A input current?

Provide a dedicated 240 V circuit rated for at least 20 A continuous load with appropriate gauge wiring and a matching receptacle.

Does the box include a power cord for my 220–240 V outlet?

The power cord is not included. You must source a cord that fits your local 220–240 V receptacle and meets the 20 A rating.
