Product Details

Bitmain Antminer S19k Pro 120TH Low Power Air Cooled SHA-256 Bitcoin Miner

Lower bin S19k Pro on 12V DC. 120 TH/s at 2,760W versus the higher bin at 136 TH/s and 3,264W. Different chip grading, different output, different power draw, but the same external PSU requirement. 12V DC at 120 TH/s draws roughly 230 amps from your power supply. That is a substantial PSU.

The S19k Pro 120 TH/s sits mid pack in the S19 generation. Above the S19j Pro (96 to 104 TH/s) but below the S19j Pro+ (117 to 122 TH/s). The "k" designation indicates a different manufacturing run. Multiple chip revisions across the S19 generation produced overlapping models with similar output but different naming.

2,760W at roughly 23.0 J/TH. Better than base S19 models (34+ J/TH) but behind the S19j XP (21.5 J/TH). 12V DC input means a separate high amperage PSU is mandatory. Factor $100 to $300 for the PSU. The total acquisition cost is miner plus PSU.

Daily electricity at $0.07 per kWh: $4.64. Monthly: $139. Bitmain Antminer firmware with extensive third party support. Braiins OS autotuning can squeeze additional efficiency from S19k Pro hardware. The S19 series has the most mature optimization ecosystem of any Bitmain generation.

195 x 290 x 370mm at 13.2 kg. 12V input. Ethernet. 5 - 45 °C. Bitmain firmware. Daily electricity at $0.07 per kWh: $4.64. Monthly: $139. Compare against Bitcoin revenue at 120 TH/s and current difficulty.

For operators: total cost of ownership equals acquisition plus electricity ($4.64 daily) times deployment days. Compare against alternatives. at your specific rate, the Antminer S19k Pro either beats alternatives on Bitcoin per dollar or it does not.

Antminer S19k Pro 120TH Low Power Cost Efficient Bitcoin Miner

Lower bin S19k Pro at 120 TH/s and 2,760W on 12V DC input. Requires a separate 12V PSU at high amperage. Different power architecture from the 136 TH/s AC model. S19 generation at 23.0 J/TH. Discount pricing for cheap electricity fleet scaling.

Air cooled at 75 dB. Bitcoin, Bitcoin Cash, all SHA 256. Bitmain firmware. 195 x 290 x 370mm at 13.2 kg. Ethernet. 5 - 45 °C.

Industrial 75 dB. Dedicated mining space required. Plan for 2760W heat exhaust.

Bitmain firmware for pool configuration and monitoring. Compare pricing against competing models at this tier. Total fleet hashrate determines coins mined. Model conservatively.

Industrial 75 dB demands dedicated space. Warehouses, containers, isolated rooms. Plan for 2760W heat exhaust through ventilation or HVAC.

Bitmain firmware for pool configuration. Evaluate pricing against competitors. Total deployed hashrate determines production. Model conservatively with current network data.

FAQ

Frequently Asked Questions

120 TH/s of SHA-256 at 2,760W with 23 J/TH efficiency. Previous-generation Bitmain miner, more affordable than S21/S23 series.

At $0.07/kWh, margins are very thin. The S19k Pro at 23 J/TH is significantly less efficient than the S21 XP (13.5 J/TH) or S23 (11 J/TH). Profitable only at very low electricity rates under $0.05/kWh. Best purchased at a steep discount for mining with ultra-cheap power.

For new investments, the S21 or S23 series offers dramatically better efficiency and long-term profitability. The S19k Pro only makes sense at deep discounts with access to very cheap electricity.
