MSI launches Cubi NUC AI+ 3MG, a 0.51L Copilot+ mini PC with Intel Core Ultra Series 3
MSI has announced the Cubi NUC AI+ 3MG, a compact business mini PC built around Intel Core Ultra Series 3 processors. The system comes in a 0.51-liter chassis and MSI is positioning it as a Copilot+ PC for office, enterprise, digital signage, and edge deployments. MSI had already shown the system at CES 2026, and the April 15 post appears to be the formal launch.
The company lists three CPU options for the series, Core Ultra 9 386H, Core Ultra 7 355, and Core Ultra 5 322 . MSI also confirms integrated Intel graphics, two DDR5 SO-DIMM slots, one M.2 2280 NVMe slot, dual Thunderbolt 4, dual HDMI 2.1 outputs, dual 2.5G LAN, and Wi-Fi 7. MSI says the system can drive up to four displays and supports VESA mounting.
The Cubi NUC AI+ 3MG includes a fingerprint-enabled power button, dTPM support, Kensington lock support, a tool-less chassis, and an external power switch header. Why have other Mini-PC makers never thought about this feature? The product page also highlights cable management, MSI Power Link support through compatible monitors, and a 120W power adapter.
The general datasheet lists 2x DDR5 SO-DIMMs up to 32GB, while a US SKU sheet for Cubi NUC AI+ 3MG-007BUS lists 96GB max and specifies the Core Ultra 7 355 for that configuration.
