Bitmain Antminer HS3 (9 TH/s)

The Antminer HS3 is a purpose-built ASIC for Handshake (HNS) mining, rated at 9 TH/s and drawing roughly 2,079–2,081 watts depending on firmware and hardware revision, which yields an energy efficiency in the order of 231 J/TH and thus positions the device as a high-performance, power-intensive unit for sustained hashing; manufacturers’ listings vary on physical dimensions and mass-some units cite a compact 331 × 234 × 391 mm, 6.1 kg chassis while others indicate a larger 430 × 195 × 290 mm, 16.1 kg frame more readily integrated into rack-mounted installations-nevertheless all revisions employ active multi-fan cooling (four fans reported), operate on 200–240 V input with Ethernet connectivity, deliver approximately 75 dB noise under load and are specified to function reliably in ambient te…mperatures from 5° to 45° C and relative humidity from 5% to 95%, making them suitable for both home and industrial environments provided adequate ventilation and electrical capacity; for robust, long-term operation the HS3 demands stable power delivery, surge protection, diligent thermal management and firmware monitoring, and miners should factor the device’s J/TH metric into operational planning, reserve headroom on electrical circuits, deploy pool settings and redundancy strategies to smooth revenue variance, and institute routine checks of fan speed, core temperature and hashrate to preserve efficiency and prolong hardware life.

Think of the Antminer HS3 as a loyal forge-beast that hums in the corner of your lair, turning steady courage into 9 TH/s of Handshake hashing. It draws roughly 2,079 watts and converts that hunger into work at about 231 J/TH. Compact at roughly 331 × 234 × 391 millimeters and weighing near 6.1 kilograms, it slips into a shelf or a rack without fuss. Four cooling fans keep its temper cool and its chips singing. It thrives between 5 and 45 °C and tolerates humidity from 5 to 95 percent. Ethernet gives it a clear voice to your monitoring tools. That mix of size and stamina makes it fit for quiet home setups and louder industrial rooms alike. For long campaigns you must provide steady power, add surge protection and leave headroom on circuits. Good airflow, routine firmware checks and pool re…dundancy keep its rhythm true. Watch fan speed, core temperature and hashrate as if caring for a small, cantankerous dragon-small changes often warn of trouble. Factor its J/TH into your power budget and margins so your venture stays brave and profitable. With simple care the HS3 repays that closeness with predictable, efficient hashing that endures.
