The MicroBT WhatsMiner M31S+ delivers 84 terahashes per second of SHA-256 Bitcoin mining power from a proven, field-tested platform. Built on TSMC's 8nm process node, the M31S+ achieves 42 joules per terahash efficiency — positioning it as a reliable mid-generation workhorse that balances meaningful hashrate with manageable electricity costs for Australian Bitcoin miners.
MicroBT was founded in 2016 by former Bitmain chip designer Yang Zuoxing, and has since grown into Bitmain's primary competitor in the ASIC manufacturing market. The WhatsMiner line is known for its robust build quality, integrated PSU design, and consistent real-world performance that closely matches advertised specifications. Unlike many competitors that require a separately purchased power supply, the M31S+ ships with a built-in 3500W PSU mounted on top of the unit — simplifying deployment and eliminating compatibility concerns around PSU connector types.
The wide-range AC input of 200–277V ensures full compatibility with Australian 240V single-phase infrastructure and most international mining facility standards. Two high-performance 12038 fans provide continuous airflow across the hash boards, keeping operating temperatures within the safe range of –5°C to 40°C. Connectivity is via standard Ethernet RJ45 — connect power and network, locate the miner's IP via your router, log into the browser-based dashboard, enter your SHA-256 mining pool stratum address, and you're producing Bitcoin hashrate within minutes.
At 84 TH/s and 42 J/TH, the M31S+ is best suited to Australian operators with electricity costs under $0.12/kWh, or those seeking a lower-cost entry point into SHA-256 Bitcoin mining. The M31S+ can be pointed at any SHA-256 compatible pool — Foundry USA, Antpool, F2Pool, ViaBTC, and OCEAN are popular choices with strong Australian server coverage. For solo mining enthusiasts, it is also compatible with CKPool Solo and Public Pool.
