Compact AI mini PC for home office

The MSI Cubi NUC AI+ 3MG-018US fits a Core Ultra 7 355 processor, 16GB DDR5 memory and a 1TB PCIe M.2 2280 drive into a 1.48 x 4.71 x 4.54 inch chassis. Windows 11 Pro and Copilot+ PC features target everyday productivity and light creative work. Two SODIMM slots allow expansion up to 64GB for heavier multitasking.

Sustained load behaviour

A 120W external supply powers the 12MB L3 cache CPU and Intel Graphics through long document, browser and video sessions. Dual Intel I226-V 2.5G LAN ports and Wi-Fi 7 keep network throughput steady when cloud sync or large file transfers run for hours. The small footprint still dissipates heat without throttling typical office workloads.

Build quality and daily connectivity

The black enclosure weighs 1.1 lbs and offers front USB 3.2 Gen2 Type-A and Type-C for quick peripheral access. Rear I/O adds two Thunderbolt4 Type-C ports with DP 1.4 alt-mode up to 4K 60Hz and 15W power delivery plus two HDMI 2.1 outputs. An external power switch lets users reboot without reaching behind the desk.

Questions about this item

How much power does the 120W adapter draw when the Core Ultra 7 355 runs all day?

The unit ships with a 120W external power supply; actual draw varies with workload but will not exceed that rating.

Which display cables must I already own to use the two HDMI 2.1 outputs?

You need two HDMI cables; the mini PC provides two HDMI 2.1 ports and no other video connectors.

Will my existing 2.5G Ethernet switch work with the dual Intel I226-V LAN ports?

Yes, each port is a 2.5G Intel I226-V controller, so a 2.5G switch will link at full speed.
