MSI Cubi NUC AI+ 3MG-004EU Mini PC – Intel Core Ultra 5 125H, 16GB DDR5, 512GB SSD, Intel Arc Graphics, Wi-Fi 6E, Windows 11 Pro, Black

MSI’s Cubi NUC AI+ 3MG-004EU redefines compact computing by pairing Intel’s Core Ultra 5 125H with a dedicated AI Boost NPU, bringing on-device AI acceleration to a footprint no larger than a paperback. Unlike standard mini PCs that rely solely on CPU and GPU, this model offloads AI workloads to the NPU, enabling smoother Copilot+ experiences, faster photo and video enhancements, and efficient multitasking without thermal throttling. The black chassis houses dual Thunderbolt 4 ports, 2.5G Ethernet, and Wi-Fi 6E, making it a future-ready hub for creators, developers, and professionals who demand desktop-class performance from a VESA-mountable box.

From the moment you power it on, the Cubi NUC AI+ feels responsive and quiet. Boot times are near-instant thanks to the Gen4 SSD, and the 16GB of DDR5 memory keeps dozens of browser tabs, office apps, and lightweight creative tools running smoothly. The NPU quietly handles AI denoising in video calls, real-time transcription, and background blur without taxing the CPU, leaving headroom for your primary tasks. The dual Thunderbolt 4 ports open doors to high-speed external storage, eGPUs, or daisy-chained docks, while 2.5G Ethernet ensures lag-free file transfers and streaming.
