MicroBT WhatsMiner M78 Immersion Cooling BTC Miner 486Th/s 7000W

MicroBT WhatsMiner M78 | 486 TH/s Immersion-Cooled Bitcoin Miner | 14.5 J/TH | Industrial-Grade Liquid Cooling

The MicroBT WhatsMiner M78 is a powerful, immersion-cooled ASIC miner engineered for professional Bitcoin mining. Delivering up to 486 TH/s at 7000W, it achieves an efficiency of 14.5 J/TH. This miner is built from the ground up for deployment in dielectric fluid, offering superior thermal management, enhanced reliability, and operational stability for high-density, large-scale mining operations.

Performance & Technology Highlights

• Optimized for Immersion Performance: The miner’s architecture is specifically tailored for dielectric fluid submersion, ensuring maximum heat transfer away from the ASIC chips. This enables sustained high performance without thermal throttling and contributes directly to its 14.5 J/TH efficiency.

• Engineered for Reliability & Uptime: Immersion cooling eliminates dust ingress, corrosion from humidity, and mechanical failure points like fans, drastically reducing maintenance needs and aiming for superior hardware longevity and operational uptime.

• Ideal for Modular, High-Density Deployment: Its compact size and efficient thermal design make it perfect for dense packing in immersion tanks, allowing operators to maximize hashrate per square foot of facility space.

• Enabler for Sustainable Operations: The efficient capture of waste heat into the dielectric fluid makes this miner highly suitable for facilities with heat recovery systems, potentially offsetting energy costs or creating ancillary revenue.

 Critical Deployment Requirements

• Mandatory Immersion Infrastructure: This is not a plug-and-play or air-cooled unit. It must be installed within a complete and compatible immersion cooling system. This includes a sealed tank, dielectric coolant, circulation pumps, piping, and heat exchangers—a significant separate capital investment.

• Industrial Power & Facility: Requires a dedicated 380-480V, 3-phase industrial power circuit and must be housed in a facility engineered for the safety, maintenance, and operational protocols of liquid immersion technology.

• Professional & Institutional Focus: The complexity and cost of the required supporting system make this miner a viable option exclusively for large-scale mining farms, institutional investors, or specialized industrial hosting providers.

• Pre-Release Product Verification: As a December 2025 release, all performance specifications are preliminary. Final hashrate, efficiency, and power consumption must be verified with official MicroBT documentation upon product launch.
