Purpose-built SHA-256 miner

The Bitmain Antminer S19j Pro 240-Cb is a dedicated ASIC system that delivers 104Th/s for Bitcoin and Bitcoin Cash mining. It draws 3120W at 29.5J/TH efficiency and connects through a 10/100M RJ45 Ethernet port. The unit measures 400 by 195.5 by 290mm and weighs 14.6kg.

Suited for 220V facilities

This model requires a 220V input; incorrect voltage can damage the hardware. It is intended for operators who can provide stable power and keep ambient temperatures between 0°C and 40°C. Buyers without access to 220V supply or adequate cooling should consider other equipment.

Rack-mount installation notes

The rectangular chassis fits standard shelving, but the 14.6kg weight demands sturdy rails or brackets. Common issues include insufficient PDU capacity for 3120W draw and restricted airflow when units are stacked too tightly. Verify voltage, power budget and clearance before powering on.

Perguntas sobre este artigo

What voltage supply must I already have for the Antminer S19j Pro 240-Cb to operate?

The miner requires a 220 V input; using a different voltage can damage the unit.

Will the RJ45 Ethernet 10/100M port work with my existing 1 Gbps network switch?

Yes, the 10/100M port will connect to a gigabit switch and negotiate at 100 Mbps.

How can I confirm the 104Th/s hashrate is being reached after setup?

Check the miner dashboard or pool statistics; they should report a rate near 104 Th/s with power efficiency around 29.5 J/TH.
