Summary

A compact mini PC built around a 24-core Intel Core i9-13900HX, sold as a barebone kit or with memory and storage preinstalled. The thing to check before buying is power: a 120W adapter and a small chassis hold the chip near its 55W sustained limit, so treat the 5.4 GHz turbo as a burst figure.

Strengths

  • 24 cores and 32 threads for CPU-bound work at a barebone price of $399 (MINISFORUM US store, 2026-10-07).
  • Two PCIe 4.0 M.2 slots and dual SO-DIMM slots let you add up to 96GB of RAM and 8TB of storage.
  • Triple 4K output, 2.5GbE and Wi-Fi 6E cover multi-monitor and home-server setups.
  • The barebone kit lets you reuse existing DDR4 memory, an NVMe drive and an OS license.
  • VESA mounting and a small 195 × 193 × 51.9 mm footprint suit a desk or the back of a monitor.

Weaknesses

  • A 120W adapter and a compact chassis hold the 157W-rated chip near its 55W sustained limit, so turbo clocks fall in long runs.
  • MINISFORUM has not published sustained-load temperature or clock-speed data for this model.
  • DDR4-3200 gives up memory bandwidth (about 51 GB/s against 90 GB/s for dual-channel DDR5) for cheaper modules.
  • There is no Thunderbolt, USB4 or OCuLink, so there is no external GPU path.
  • There is no NPU, and every port is rear-mounted, with no front USB.
  • One Level1Techs report describes an i9-13900HX failure after about a year in a different MINISFORUM model.

Performance, power and thermals

The i9-13900HX is a laptop-class chip rated at 55W base and 157W maximum turbo. In the M1 chassis, a single turbine blower and three copper heat pipes feed a 120W external adapter, so sustained loads settle at or near the 55W long-term limit rather than the 157W peak. MINISFORUM’s 5.4 GHz figure is a burst clock. The company claims 7-13% better single-core and around 20% better multi-core than the M1-1295; PassMark CPU Mark shows a wider gap of about 32% (roughly 41,400 for the i9-13900HX against 31,000 for the i9-12950HX). Le Verger expects audible fan noise under heavy multi-core loads, and no independent outlet has published instrumented thermals for the exact model.

Memory, storage and ports

Two SO-DIMM slots take DDR4-3200 up to 96GB, and two M.2 2280 PCIe 4.0 x4 slots take up to 4TB each for 8TB total. DDR4 is cheaper than DDR5 but narrower; TechTimes puts the dual-channel gap at roughly 51 GB/s against 90 GB/s, and says DDR5 can cut render times by 10-20% in bandwidth-sensitive work. For ports you get HDMI 2.1, DisplayPort 1.4 and USB-C DP Alt Mode for triple 4K, 2.5GbE, Wi-Fi 6E and Bluetooth 5.2. Two of the four USB-A ports are USB 2.0, all ports are on the back, and there is no SD card reader, fingerprint sensor, speaker or microphone.

Repairs, running costs and warranty

Routine costs are memory and storage if you buy the barebone kit, an OS license if you need Windows, and electricity; there is no subscription or consumable. A 32GB DDR4-3200 kit runs about $150-220 against around $370 for equivalent DDR5-5600 in mid-2026 (TechTimes). The case opens for SO-DIMM and M.2 upgrades, and MINISFORUM describes the phase-change thermal material as easy to maintain. One owner in a Level1Techs thread paid a $120 fee to replace the board after an i9-13900HX failed in a different MINISFORUM model, with support requiring video proof of the failure first. Warranty length is unverified: Smarthomecompared states two years, but MINISFORUM’s own store page does not confirm it and BestBuy does not state it. MINISFORUM’s UK store lists the barebone at £369 (sale from £459), and the US store lists the three builds at $399 (from $499), $599 (from $749) and $767 (from $959); BestBuy lists the same three at $399, $599 and $767.

Is it worth it?

The value case is CPU throughput per dollar. At $399 barebone you get 24 cores and 32 threads, triple 4K, 2.5GbE, Wi-Fi 6E and two PCIe 4.0 M.2 slots. That suits code compilation, virtualization, CPU rendering and multi-monitor productivity. At $599 with 16GB and 500GB it stays strong for a ready-to-run system with upgrade headroom. At $767 with 32GB and 1TB it is competitive, but buyers who need memory bandwidth or on-device AI should compare DDR5 platforms with NPUs such as Intel Core Ultra or AMD Ryzen AI. Buyers should also weigh the missing Thunderbolt, USB4 and OCuLink, and the absence of any instrumented third-party test.

Which model this is

This page covers the MINISFORUM M1-1390, model number M1-1390, SKU M1-139000US, launched in August 2026. It is the 13th-generation Intel refresh of the M1-1295: same chassis, ports, DDR4 support, M.2 slots and 120W adapter, with the Core i9-13900HX replacing the i9-12950HX (24 cores and 32 threads against 16 and 24). It is sold as a barebone kit or with 16GB/500GB or 32GB/1TB installed. Do not confuse it with the M1-1295, the NAB9S or other MINISFORUM models. The listing ID is ASIN B0FJL6MCT9.
