MicroBT WhatsMiner M78S 472Th/s 6550W Immersion Cooling BTC Miner

MicroBT WhatsMiner M78S | 472 TH/s Immersion-Cooled Bitcoin Miner | 13.877 J/TH | Industrial-Efficiency ASIC
The MicroBT WhatsMiner M78S is a high-efficiency, immersion-cooled ASIC miner engineered for professional Bitcoin mining operations. Delivering 472 TH/s at 6550W, it achieves an efficiency of 13.877 J/TH. Designed exclusively for deployment in dielectric fluid, the M78S leverages immersion technology for maximum thermal stability, hardware longevity, and operational quietness, making it a strategic choice for large-scale, infrastructure-focused mining facilities.
Performance & Technology Highlights


Optimized Immersion Design: Built from the ground up for dielectric fluid submersion, ensuring optimal heat transfer directly from the ASIC chips, which enables sustained high performance and dramatically reduces failure rates associated with fans and dust.


Industrial-Grade Efficiency: The 13.877 J/TH efficiency, combined with the superior cooling of immersion, targets a lower total cost of ownership (TCO) for operations where electricity and hardware longevity are primary cost drivers.


Ideal for High-Density & Heat Reuse: The compact form factor and efficient heat transfer make it perfect for dense deployment in immersion tanks. The captured waste heat can be repurposed for industrial or residential heating, creating potential additional revenue streams.


Operational Stability: Immersion cooling eliminates thermal throttling and provides a consistent operating temperature, which is crucial for predictable mining output and hardware reliability.


Critical Deployment Requirements


Mandatory Immersion Infrastructure: This miner is not operational with air or standard hydro cooling. It requires a complete and compatible immersion cooling system, including a sealed tank, dielectric coolant, circulation pumps, piping, and a heat exchanger. This represents a substantial additional capital and operational investment.


Industrial Power & Facility: Requires a dedicated 380-480V, 3-phase industrial power circuit. It must be installed in a professional facility designed to house and maintain liquid immersion infrastructure.


Professional & Institutional Exclusive: The complexity and cost of the required supporting system make this miner viable only for large-scale mining farms, institutional investors, or specialized hosting providers with existing immersion expertise.


Pre-Release Product Note: As a December 2025 release, all specifications, including the stated efficiency, are preliminary and subject to final validation by MicroBT upon official launch.
