Compact AI-Ready Mini PC

The MSI Cubi NUC AI+ 3MG-020US is a 1.1 lb black mini PC powered by an Intel Core Ultra 7 355 processor with 12 MB L3 cache. It ships with 16 GB DDR5 SODIMM memory across two slots, a 1 TB PCIe M.2 2280 NVMe drive, and Windows 11 Home. A 120 W external supply powers the Intel Graphics engine.

Suited for Copilot Workloads, Not Heavy Gaming

This system targets students and home-office users who want on-device Copilot+ AI features, dual 2.5 GbE Intel I226-V LAN, Wi-Fi 7, and Bluetooth 5.4 in a 1.48 x 4.71 x 4.54 inch chassis. Buyers needing discrete graphics performance, more than 64 GB RAM, or additional internal drive bays should consider a larger desktop platform.

Two HDMI 2.1 Video Outputs

Front I/O provides one USB 3.2 Gen2 Type-A and one Type-C port. The rear adds two USB 3.2 Gen2 Type-C ports with DisplayPort 1.4 alt-mode up to 4K at 60 Hz and 15 W power delivery, plus two HDMI 2.1 connectors for multi-monitor setups.

Questions about this item

How easy is it to replace the 1TB PCIe M.2 2280 M-Key SSD if it fails?

The M.2 2280 M-Key slot is accessible inside the chassis; swapping the 1TB PCIe drive only requires removing the bottom cover and one screw.

Which limit appears first when the Core Ultra 7 355 runs at full load for hours?

The 120W power adapter caps sustained performance before the thermal solution reaches its ceiling.

How loud and hot does the unit get when it runs all day with Wi-Fi 7 and Bluetooth 5.4 active?

Fan noise stays at a low office hum and the case remains warm but comfortable to touch during continuous operation.
