Purpose & Audience
The Stellapex NerdQX 8.1 TH/s is a compact SHA-256 solo miner built for home or office use. It delivers 8.1 TH/s hash rate while drawing 138 W at the wall, yielding an efficiency of 17 J/TH. The orange chassis measures 22×12×15 cm and weighs 1.01 kg, cooled by three fans that keep noise below 40 dB.
Fit & Limits
This unit suits individuals who want a quiet, low-power device for lottery-style Bitcoin mining on a 2.4 GHz Wi-Fi network. It is not for operators who need rackmount density, Ethernet connectivity, or hash rates measured in hundreds of terahashes. Buyers expecting pool payouts comparable to industrial hardware will not see that scale here.
Deciding Spec
The 8.1 TH/s hash rate at 138 W power draw is the single figure that determines whether this miner matches your electricity cost and earnings target. At 17 J/TH it sets the baseline for daily coin output and payback calculations.

Questions about this item
Which hashrate version of the Stellapex NerdQX should I pick for home solo mining?
The SMT-NerdQX-8.1 model delivers 8.1 TH/s using four 7 nm BM1370 ASIC chips and is the only version listed for this product line.
What does the 8.1 TH/s figure mean once the miner is running in my house?
It means the unit can perform 8.1 trillion SHA-256 hashes every second while drawing 216 W from the wall, yielding an efficiency of 17 J/TH under typical 2.4 GHz Wi-Fi pool connectivity.
What network interface does the NerdQX use and what does it limit in practice?
Built-in 2.4 GHz Wi-Fi handles pool connection and remote monitoring through the NerdX control panel; it caps the miner to 2.4 GHz networks only.
