MSI Cubi 5 1M

Manufacturer: MSI

The MSI Cubi 5 1M is a compact Mini PC built around a low-power processor and designed to fit into tight spaces without sacrificing capability. Its Micro-ATX form factor keeps the overall volume under 826 cm³, with dimensions of 124 × 124 × 53.7 mm, making it well-suited for deployments where desk space is limited. The unit ships with a 2TB NVMe SSD using flash storage, and supports up to 64GB of DDR5 memory across two channels.

On the connectivity side, the Cubi 5 1M offers a solid range of ports including four USB 3.2 Gen 2 Type-A ports, one USB 4 40Gbps port, and a single Thunderbolt 4 port. Display output is handled via one HDMI 2.1 port and one DisplayPort 1.4 output, with the integrated Intel Iris Xe Graphics G7 96EU supporting up to four displays simultaneously. Networking is covered by dual RJ45 ports alongside Wi-Fi 6E and Bluetooth 5.3. In benchmark testing, the system achieves a PassMark score of 15,289 and a Geekbench 6 multi-core result of 7,404.

Pros
  • Supports up to four simultaneous display outputs, making it suited for multi-monitor setups in a compact form factor
  • Includes a Thunderbolt 4 port and a USB 4 40Gbps port, enabling high-speed peripheral and display connections
  • Wi-Fi 6E support alongside dual RJ45 ports provides flexible wired and wireless networking options
  • The 2TB NVMe SSD offers substantial storage capacity for a Mini PC of this size
  • 64GB of DDR5 RAM running at 5200 MHz represents the maximum supported capacity, leaving no room for future memory upgrades to go unmet
  • big.LITTLE CPU architecture allows mixed core operation, balancing workload distribution within the 15W power envelope
Cons
  • No 3.5 mm headset jack means audio peripherals require an adapter or alternative connection method
  • The CPU multiplier is locked, removing any possibility of manual frequency adjustments
  • ECC memory is not supported, which limits suitability for error-sensitive or high-reliability workloads
  • No external memory slot restricts expandable or removable storage options
  • The 15W TDP places a ceiling on sustained processing throughput for demanding tasks
  • Single-core PassMark score of 3,556 and Geekbench 6 single-core of 2,142 indicate modest per-core output
Who is this for?

This Mini PC is well-matched for users who need a space-efficient desktop solution capable of handling multi-monitor productivity setups, given its support for up to four simultaneous displays via HDMI 2.1, DisplayPort 1.4, and Thunderbolt 4. The 64GB of DDR5 RAM and 2TB NVMe SSD make it a practical fit for office workloads, content management, and light creative tasks that benefit from fast storage access and ample memory. Its dual RJ45 ports and Wi-Fi 6E support also make it a strong candidate for network-intensive environments such as small business deployments or home office setups where both wired redundancy and fast wireless connectivity are useful.

Who is this NOT for?

Users looking to run GPU-intensive applications such as 3D rendering, video editing with hardware acceleration, or modern gaming will find the integrated Iris Xe Graphics G7 insufficient for those demands. The locked CPU multiplier and 15W TDP also make this a poor fit for anyone seeking sustained high-performance compute tasks, as the processor is not tunable and is thermally constrained by design. Additionally, the absence of a 3.5 mm audio jack and S/PDIF output rules it out for users who rely on direct analog or digital audio connectivity without additional hardware.
