Used Bitmain Antminer S19k Pro 120 TH/s – Bench Tested — in stock now at Bitcoin Mining Depot and shipped worldwide from our Hong Kong facility. This listing is the most popular entry-level industrial bitcoin miner in the used market, and the exact machine you see in the photos is the machine we ship. Every unit is opened, cleaned, benched under sustained load and logged against its serial number before it is released for dispatch.
Performance and specifications: this Bitmain miner runs the SHA-256 algorithm at 120 TH/s while drawing about 2760W at the wall, for a rated efficiency of 23 J/TH. It mines BTC / BCH. Efficiency is the number that decides whether a machine survives the next difficulty increase, so compare 23 J/TH against your own electricity rate before ordering — our desk will run the break-even model with you if you send your power cost and pool fee.
Infrastructure requirements: plan for a 200-240V supply, strong intake and exhaust airflow, dust filtration and somewhere that tolerates industrial fan noise — a garage, outbuilding, container or hosted rack. If you do not have suitable space, our hosting programme can run this unit for you with power, cooling, monitoring and remote reboots included.
Condition and testing: this unit is graded Used. Hashboard temperatures, fan RPM and pool-side accepted shares are logged against the serial number during testing and shared on request. Refurbished stock carries a limited hashboard and PSU warranty, and used stock ships with a functional-on-arrival guarantee plus a 180-day service window through our in-house repair centre.
Who it suits: first-time industrial buyers and hosting customers filling racks on a budget. Wholesale pricing applies from five units upward, and multi-unit orders are consolidated onto one freight booking to cut shipping cost per machine.
Shipping and payment: worldwide delivery to the USA, Canada, Europe and Asia with DDP options available, express transit typically 7-14 days, and dispatch within 24 hours of cleared payment. Pay in Bitcoin, USDT or another supported cryptocurrency at checkout, or message our team on WhatsApp for a same-day quote and a testing video of the exact unit.
Follow these steps in order to go from delivery to a live, hashing machine. Most deployments are online the same day, and our support desk will stay on the call with you until the miner hits its rated hashrate.
Provision a dedicated 200–240V circuit per unit with 20% breaker headroom and a PDU rated for continuous load — a standard residential outlet cannot run this machine.
Mount the miner with unobstructed intake and exhaust, keep intake air below 35°C, and run negative-pressure exhaust so hot air is never recirculated.
Connect Ethernet — Wi-Fi is not supported. Power on, wait about 60 seconds, then locate the machine using the manufacturer's IP reporter tool or your router's DHCP client list. Open that IP in a browser and sign in to the web dashboard, then immediately change the default password.
Create a receiving address for the coin you intend to mine, add it to your pool account payout settings, then enter the pool stratum URL, worker name and password in the miner's Pools tab. Configure two backup pools for automatic failover.
Save the configuration and let the machine warm up for 15–20 minutes. Confirm the dashboard shows the rated 120 TH/s with zero hardware errors, and check the same worker appears live on your pool page. Watch board temperatures and fan speeds for the first hour.
Set pool alerts for offline workers, review payouts after the first 24 hours, and schedule maintenance — quarterly dust cleaning and fan inspection. Bitcoin Mining Depot provides free remote setup assistance and 24/7 technical support for every unit we ship.
