Product Overview

The NerdQaxe++ 4.8T is a compact, open-source Bitcoin (SHA-256) ASIC miner designed specifically for home and small-scale mining setups. Powered by four Bitmain BM1370 chips, it delivers up to 4.8 TH/s hashrate while drawing only around 72–80W at the wall – giving you full-size ASIC hash power in a tiny, ultra-efficient package.

With built-in 2.4 GHz Wi-Fi, a local web dashboard and an on-device display, the NerdQaxe++ is ideal for enthusiasts who want a quiet, low-power, plug-and-play Bitcoin miner that can run on a desk, shelf or small rig at home.

Key Features

• 4.8 TH/s SHA-256 performance
  Delivers approximately 4.8 TH/s (±5%) on the SHA-256 algorithm, suitable for mining Bitcoin (BTC) and other SHA-256 coins.

• Ultra-low power consumption
  Typical power draw of around 72–80W, with energy efficiency in the region of ≈15–16 J/TH, making it one of the most power-efficient home miners available.

• 4 × BM1370 ASIC chips
  Uses four BM1370 chips from Bitmain’s latest-generation S21-series miners, bringing modern ASIC efficiency into a small home-friendly form factor.

• Quiet operation (~40 dB)
  Designed for home and office environments with a low-profile cooler and a single fan, producing roughly 40 dB of noise – comparable to a quiet desktop PC.

• Built-in Wi-Fi & web interface
  Integrated 2.4 GHz Wi-Fi and a simple web dashboard let you configure pools, check hashrate and monitor temperatures from your browser without needing extra controllers.

• On-device colour display
  A small LCD screen shows real-time hashrate, temperature, network status and other stats directly on the miner.

• Open-source firmware (AxeOS family)
  Based on open-source firmware, giving enthusiasts access to community updates, tweaks and tuning options.

Power, Cooling & Installation Notes

The NerdQaxe++ is designed to be simple and home-friendly:

• It runs from a small 12V DC power adapter (included with most bundles), which plugs into a standard 100–240V AC wall socket.

• With a power draw under 80W, it can share a circuit with other household devices without special electrical work, as long as normal load limits are respected.

• The compact cooler and single fan mean:

  • No large hot air exhaust like full-size ASICs.

  • Comfortable operation on a desk, shelf or small rack, provided the area is well ventilated.

• Avoid enclosing the miner in sealed cabinets, and keep intake/exhaust vents clear to maintain good airflow and safe temperatures.

Ideal Use Cases

• Home Bitcoin miners who want a quiet, low-power ASIC running in a living area, home office or small mining corner.

• Enthusiasts and hobbyists interested in open-source hardware and firmware who want to experiment, tune and learn.

• Small mining setups that value energy efficiency, compact size and minimal noise over large-scale hash power.

The NerdQaxe++ 4.8T is especially well suited as a desk-side or shelf-mounted miner for anyone who wants “real” ASIC hash power without the sound and heat of traditional full-size miners.
