Who it fits

Key specs explained for M1-1390

Intel Core i9-13900HX

This processor features 24 cores and 32 threads with speeds up to 5.4GHz. The hybrid architecture combines performance and efficiency cores for heavy multitasking. You benefit from smooth operation when running complex applications or editing video. This high-end CPU handles demanding workloads better than lower-tier i5 or i7 models in the mini PC market.

32GB DDR4 3200MHz RAM

This memory capacity allows you to run multiple applications simultaneously without slowdowns. The 3200MHz speed ensures efficient data transfer between the processor and memory modules. You can keep many browser tabs and office programs open at once. This amount of RAM is suitable for power users who need more headroom than the standard 16GB found in many compact desktops.

1TB PCIe 4.0 SSD

This storage drive provides fast boot times and quick file access for your operating system and applications. The PCIe 4.0 interface offers higher bandwidth than older PCIe 3.0 drives. You will notice faster loading speeds for large files and games. This capacity is sufficient for most users, though the dual slot design allows expansion to 8TB if you store extensive media libraries.

Intel UHD Graphics

This integrated graphics solution handles display output and basic visual tasks. It supports 4K video playback and simple design work without requiring a separate video card. You can connect up to three 4K displays for a multi-monitor setup. While not ideal for high-end gaming, it is adequate for office productivity, media consumption, and light creative editing on a compact form factor.

2.5GbE Ethernet

This network port offers speeds 2.5 times faster than standard Gigabit Ethernet. You benefit from reduced latency and quicker file transfers when connected to a compatible router or NAS. This is useful for large data backups or streaming high-bitrate content. It provides a more stable and faster wired connection option compared to relying solely on Wi-Fi for critical network tasks.

Design and build overview

The listing describes the MINISFORUM M1-1390 as having a compact form factor. It states the volume is only 7% of a standard desktop computer. This small footprint allows you to place it easily on a desk or mount it behind a monitor. The color is listed as silver, with a white and silver dual-color inlay design. The body features smooth lines, which the manufacturer notes makes it attractive for office and conference room environments. According to the listing, the exterior finish is designed to be elegant and visually pleasing in professional settings.

The layout prioritizes connectivity without adding bulk. You get a 2.5GbE LAN port, USB-C, HDMI 2.1, and DisplayPort 1.4 on the front or rear panels. There are also two USB 3.2 Gen2 ports and two USB 2.0 ports. This mix lets you connect high-speed peripherals and multiple displays simultaneously. The inclusion of a 2.5G Ethernet port means you can achieve faster wired network speeds than standard gigabit connections, which is useful for large file transfers. The compact size and extensive port selection make this unit suitable for users who want a powerful desktop replacement that does not take up much physical space.

Setup and daily use overview

Setting up this mini PC involves connecting your peripherals to its extensive port selection. You have one USB-C port that supports DisplayPort, data transfer, and power delivery. This allows you to connect a single display or charge a device through the same cable. The system also includes one HDMI 2.1 TMDS port and one DisplayPort 1.4. This configuration supports triple 4K displays at 60Hz, which is useful for multi-monitor workflows in office or home environments. For networking, you can plug into the 2.5GbE LAN port for wired stability or use Wi-Fi 6E for wireless connectivity with lower latency. Bluetooth 5.2 lets you pair headsets, mice, and keyboards without dongles. The audio section provides dedicated MIC IN, LINE IN, and LINE OUT jacks for external speakers or microphones. Daily use relies on the Intel Core i9-13900HX processor with 24 cores and 32 threads. Combined with 32GB of DDR4 RAM, the system handles heavy multitasking smoothly. The 1TB PCIe 4.0 SSD ensures fast loading times for applications and large files. You can expand storage using the dual M.2 slots, supporting up to 8TB total capacity. The compact size, taking up only 7% of a standard desktop’s volume, keeps your workspace uncluttered. This setup suits users who need strong processing power and flexible display options in a small form factor.

Before You Buy This Mini PC

You should verify your monitor inputs before purchasing. This unit supports up to three 4K displays via HDMI 2.1, DisplayPort 1.4, and USB-C. Ensure your displays match these interfaces for a triple setup. Check your existing peripherals for USB compatibility. The listing includes two USB 3.2 Gen 2 ports and two USB 2.0 ports. You may need a hub if you have many devices. Consider your network needs. The 2.5GbE LAN port offers faster speeds than standard Gigabit Ethernet. Verify your router supports this for optimal performance. Wi-Fi 6E provides lower latency for wireless connections. Storage expansion is possible with dual M.2 slots. You can add more SSDs if the 1TB drive fills up. This model fits well among other small form factor computers for office or home use. It offers strong multi-core performance for heavy tasks. Compare it with other i9 options if you need even more power.

Check before you buy

• Verify your monitors support HDMI 2.1 or DisplayPort 1.4 for triple display setups.
• Check if your router supports 2.5GbE LAN for maximum wired network speeds.
• Ensure you have enough USB ports for all your peripherals or buy a hub.
• Confirm Wi-Fi 6E compatibility with your wireless devices for low latency connections.
