Compact Mini PC for Business

The MSI Cubi NUC 1MG-012UST is a 0.826-litre desktop powered by an Intel Core 5 120U processor with ten cores and a 5.00 GHz turbo frequency. It ships with Windows 11 Pro 64-bit, 16 GB of DDR5 5200 memory and a 1 TB NVMe SSD. A 120 W supply and VESA mount points for 75x75 or 100x100 mm brackets complete the package.

Suited to Office and Signage Deployments

This unit fits workers who need a silent, space-saving system for productivity apps, video calls and digital signage. Buyers who want discrete graphics performance, user-upgradeable memory slots or multiple 2.5-inch drive bays should look at something else.

16 GB DDR5 and 1 TB NVMe Headroom

The dual-channel DDR5 configuration handles heavy multitasking and large datasets without paging. The 1 TB NVMe drive holds the OS, applications and a deep project archive with room to spare. Workloads that demand GPU compute, more than 16 GB of RAM or multi-terabyte local storage will exceed the built-in capacity.

Questions about this item

What monitor connections does the Cubi NUC 1MG-012UST need to drive a display?

Yes, the Cubi NUC supports both 75x75 mm and 100x100 mm VESA patterns, matching the majority of monitor arms and wall brackets.

How can I verify the 16 GB DDR5 5200 memory is running in dual-channel mode after setup?
