Purpose-built Bitcoin miner

The Stellapex S19K Pro is an ASIC miner designed for SHA-256 coins such as BTC, BCH and BSV. It delivers a baseline hashrate of 120 TH/s using 231 BM1366 chips spread across three hash boards. An RJ45 Ethernet 10/100M link connects the unit to any major mining pool.

Sustained-load behaviour

At the wall the system draws 2760 W ±5% while maintaining 23 J/TH efficiency during continuous operation. Firmware can raise the hashrate to 136 TH/s without changing the power envelope. The miner is rated for 24/7 duty in ambient temperatures from 0 to 40 °C and 10–90 % RH non-condensing.

Thermals, noise and power

Four integrated fans keep the chassis within its 0–40 °C operating window while producing 75 dB of acoustic output. The included PSU accepts 200–240 V AC at 47–63 Hz, so the unit plugs directly into standard industrial or data-centre supplies. Power efficiency remains fixed at 23 J/TH across the supported temperature range.
