Compact Windows 11 Pro Desktop

The MSI Cubi 5 Professional is a mini tower desktop built around an Intel Core i3-1215U processor with 6 cores and 8 threads. It ships with 8GB of DDR4 3200 memory and a 512GB PCIe SSD. Windows 11 Pro is pre-installed, providing BitLocker encryption and Remote Desktop for business use.

Home-office workers and light multitaskers

This system suits users who need a small, quiet PC for office applications, video calls and web browsing with support for up to three 4K displays. Buyers who require discrete graphics performance, more than two memory slots, or internal 3.5-inch drive bays should look at something else.

65W power adapter limits sustained load

The included 65W power supply defines the thermal ceiling for the i3-1215U and its integrated Intel UHD Graphics. If a workload regularly pushes the CPU toward its 4.4 GHz turbo frequency, the brick may become the bottleneck.

Questions about this item

Will the two RJ45 ports let me keep my older wired NAS and a legacy printer on separate networks?

Yes, the dual RJ45 ports provide two independent Gigabit Ethernet connections so you can run the NAS and printer on different subnets without extra adapters.

How can I confirm the Thunderbolt 4 port is active and delivering full bandwidth after I plug in my dock?

Open Device Manager, expand System devices and verify Intel Thunderbolt 4 Controller appears without errors; then run a 4K video file from the docked SSD and check for smooth playback.

Does the box include a keyboard, mouse or monitor cables, or must I buy them separately?

The package contains the mini desktop, 65 W power adapter and Windows 11 Pro licence; keyboard, mouse, HDMI and DisplayPort cables are not included.
