Bitmain Antminer S19 - 110TH/s @ 3980 Watt - Lightly Used A Grade & Professionally Tuned (ships from USA)

I currently have these units RUNNING AT MY FACILITY and can even provide video footage if you're nearby and interested in picking them up.

These units utilize advanced firmware that tunes each chip individually, resulting in a STABLE AND RELIABLE long term operation. They can achieve 120TH/s at 4200 watts or less, but can easily even be tuned above this threshold. explained below

I RECOMEND AND I RUN MINE PERSONALLY AT 110TH/s BECAUSE IT USES JUST UNDER 400 WATT AND IS VERY VERY STABLE AND KEEPS EFFECIENCY IN THE 30s of watts per Th/s - SO THIS IS HOW THEY COME PRE TUNED.. YOU CAN CHANGE THE SETTINGS TO HIGHER OR LOWER AT YOUR WILL BUT RIGHT OUT OF THE BOX WITH NOTHING FROM YOU, NOTHING YOU NEED TO DO, THEY WILL PLUG IN AND RUN AT 110TH/s

Most users have reported achieving 120TH/s without any errors, faults, or temperature alerts. WITHOUT the need for any modification at all - Now that said with an upgraded power supply or liquid cooling. The chip limit is far above 120TH/s, as it can handle this workload without any issues even with air cooling alone. The only limiting factor is the maximum wattage of the power supply. Currently this unit is air cooled and is STABLE AND RELIABLE and running untill sold at the temp controlled USA MiningCrate official facility
