Ready-to-use mini PC

The MSI Cubi NUC AI 1UMG-044US ships with Windows 11 Home installed and an Intel Core Ultra 5 125H processor. Its 14-core design and integrated Intel Arc graphics target everyday productivity, streaming and light creative work in a compact black chassis.

Memory and storage headroom

Sixteen gigabytes of DDR5 5200 memory handle multitasking and browser-heavy workloads comfortably. The single 1 TB M.2 2280 drive offers fast boot and app loads, while a second slot allows expansion up to 64 GB total memory when larger datasets demand it.

Thermals and power in daily use

A 120 W power adapter feeds the system, which runs quiet during typical office tasks and media playback. The small form factor limits sustained heavy compute, so prolonged renders or gaming sessions will hit thermal limits sooner than a full-size desktop.

Questions about this item

Can I add my older DDR5 5200 SoDIMM sticks to the second slot to reach 64 GB?

Yes, the board has two DDR5 SoDIMM slots running at 5200 MT/s and supports up to 64 GB total, so an additional stick will work.

How can I verify the Intel Arc graphics are active after I install Windows 11 Home?

Open Device Manager, expand Display adapters, and confirm Intel Arc Graphics appears without a warning icon; the driver version will also show in the Intel Graphics Command Center.

Does the package include a monitor or just the 120 W power adapter and the mini PC?

The box contains the Cubi NUC AI 1UMG-044US unit and its 120 W power supply; a monitor is not included and must be purchased separately.
