Purpose-built solo miner

The Stellapex NerdQX-8.1T is a dedicated SHA-256 solo miner designed for home or office use. It targets Bitcoin and compatible SHA-256 currencies with a compact 22 by 12 by 15 cm chassis that weighs 1010 grams.

Plug-and-play with WiFi

Setup requires only the included AC adapter and a 2.4 GHz WiFi connection to the NerdX control interface. The three integrated fans keep temperatures stable, though the 216 W adapter draw means a standard outlet must supply enough continuous current.

8.1 TH/s at 138 W

Four BM1370 chips deliver 8.1 TH/s while the unit itself draws 138 W, yielding an efficiency of 17 J/TH. That hashrate suits lottery-style solo mining; it will not compete with industrial pools and profitability drops sharply when network difficulty rises.
