Compact AI mini PC for daily work

The MSI Cubi NUC AI+ 3MG-021US is a small-form desktop built around an Intel Core Ultra 5 322 processor. It ships with 16GB DDR5 memory and a 1TB PCIe M.2 2280 M-Key drive. Windows 11 Pro and Copilot+ PC features are included for mainstream home and office tasks.

Suits space-constrained desks and light workloads

This unit fits users who need a quiet, low-footprint system for browsing, document editing and video calls. Buyers who require discrete graphics performance, additional internal drive bays or more than two memory slots should consider a larger chassis.

1TB PCIe M.2 2280 M-Key storage decides fit

The single M.2 2280 M-Key slot holds the included 1TB NVMe drive and sets the maximum internal capacity unless external storage is added. Verify that this capacity and the single-slot design match the intended workload before purchase.

Questions about this item

How do I confirm the Core Ultra 5 322 is running Copilot+ features after setup?

Open Windows Settings, go to Privacy & Security > Copilot, and verify the NPU driver shows as active; the 12 MB L3 cache and 16 GB DDR5 will be listed under System > About.

What comes in the box and what must I buy separately for the Cubi NUC AI+ 3MG-021US?

The mini PC, 120 W power adapter, and Windows 11 Pro licence are included; no monitor, keyboard, mouse or extra DDR5 SODIMM modules are supplied.

Should I choose the 16 GB DDR5 / 1 TB PCIe M.2 2280 M-Key version or add more memory later?

The unit ships with 16 GB DDR5 in one of two slots and supports up to 64 GB; the 1 TB NVMe SSD fills the single M.2 2280 slot, so storage expansion requires an external drive.
