Minisforum UM750L Slim

Manufacturer: Minisforum

The Minisforum UM750L Slim is a compact Mini PC built around a six-core processor with a base clock of 3.2 GHz and a turbo frequency reaching 4.9 GHz. Running at a 28W TDP, it balances processing capability with a slim physical footprint, measuring 126.5 mm wide, 130 mm deep, and just 50.4 mm tall — resulting in a total volume under 829 cm³. The unit ships with a 1TB NVMe SSD and carries a two-year warranty.

On the memory side, the UM750L Slim is equipped with 32GB of DDR5 RAM running at 6400 MHz across dual channels, with a maximum supported speed of 7500 MHz. Graphics are handled by the integrated Radeon 740M, clocked at 800 MHz with a turbo of 2800 MHz, supporting up to four simultaneous displays via a combination of one HDMI 2.1 port, one DisplayPort output, and a Thunderbolt 4 port. Connectivity options include Wi-Fi 6E, Bluetooth 5.3, one USB 4 40Gbps port, two USB 3.2 Gen 2 Type-A ports, two USB 2.0 ports, and a single RJ45 Ethernet jack.

Pros
  • Supports up to four simultaneous display outputs, making it suited for multi-monitor setups
  • DDR5 RAM running at 6400 MHz across dual channels provides fast memory throughput
  • Wi-Fi 6E support ensures compatibility with the latest wireless networking standards
  • The Thunderbolt 4 port and USB 4 40Gbps port offer high-bandwidth connectivity options
  • A 1TB NVMe SSD delivers quick storage access without relying on slower flash-based storage
  • The compact volume of under 829 cm³ keeps the physical footprint small for a desktop unit
Cons
  • Maximum RAM is capped at 32GB with no support for ECC memory, limiting reliability-sensitive workloads
  • The CPU multiplier is locked, so clock speeds cannot be adjusted beyond factory settings
  • No USB 3.2 Gen 1 or Type-C ports are available outside of the USB 4 connection, reducing low-cost peripheral flexibility
  • There is no S/PDIF output, restricting digital audio options for home theater or audiophile setups
  • With only 4 GPU execution units, graphically demanding tasks are constrained by the integrated graphics hardware
Who is this for?

This Mini PC is well-suited to users who need a capable desktop workstation in a minimal footprint, such as those setting up a compact home office or media hub. The support for up to four simultaneous displays makes it a practical choice for productivity-focused environments that rely on multi-monitor arrangements. Users who benefit from fast wireless networking will appreciate the Wi-Fi 6E support, and the combination of a 1TB NVMe SSD with 32GB of DDR5 RAM at 6400 MHz makes it a reasonable fit for everyday computing, light content work, and multitasking without the bulk of a traditional desktop.

Who is this NOT for?

Users with demanding graphics workloads — such as gaming at high settings, 3D rendering, or video production requiring dedicated GPU resources — will find the four-execution-unit Radeon 740M insufficient for those tasks. The locked CPU multiplier also means the system is not appropriate for anyone interested in overclocking or performance tuning. Additionally, professionals working in environments that require ECC memory for data integrity, such as scientific computing or financial processing, will need to look elsewhere, as ECC is not supported and maximum memory is capped at 32GB.
