Bitmain Antminer S19j Pro

The used and refurbished Bitmain Antminer S19j Pro comes fully tested and dust-free, pushing roughly 96 TH/s at about 2.83 kW—around 29.5 J/TH—on stock Bitmain firmware, while a switch to Braiins OS+ can cut consumption to around 23.5 J/TH (chip quality permitting); you can order it either with Braiins OS+ pre-installed for maximum efficiency from day one or in its original Bitmain OS configuration, ready to mine and upgradeable later.

Each miner integrates a single 200–240 V APW12 PSU equipped with two IEC C14 power inlets—so it needs two power cords, weighs about 17 kg and is rated for ambient temperatures from 0 °C to 40 °C, making it equally at home in a residential rack, a mobile container farm or as overflow capacity in a data centre.

Please note: The miners are used and have been used in mining farms for varying lengths of time. There are therefore also visible signs of use.
