📋 Technical Specifications

🎨 Design and Construction Quality

Minisforum UM750L Slim mini PC 

The UM750L Slim features a high-quality aluminum and plastic design with a silver-gray finish, very similar in proportions to a Mac Mini but slightly taller (50 mm). Its 130 × 126.5 × 50.4 mm chassis makes it extremely discreet on any desk, and the included VESA mount allows it to be attached directly behind a monitor.

The perimeter ventilation grille is well distributed, and the power button on the front has a status LED (which some users have noted is too bright in dark environments). Overall, the build quality is remarkable for its price, with no creaks or looseness in the chassis.

🖥️ Screen and Multimedia

The UM750L Slim supports up to three simultaneous displays thanks to its combination of HDMI 2.1, DisplayPort 1.4, and USB4. It can reach resolutions of 8K@60Hz via HDMI 2.1 or 4K@120Hz in specific configurations, making it a very attractive option for high-resolution multi-monitor setups.

Local 4K video playback and streaming are completely smooth. The Radeon 740M with hardware decoding supports H.265, AV1, and VP9, ​​so platforms like YouTube 4K, Netflix, and Prime Video work flawlessly.

⚡ Performance and Software

The Ryzen 5 7545U —manufactured on a 4nm process with a hybrid Zen 4 + Zen 4c architecture—matches or surpasses chips like the i5-1235U in multithreaded tasks and clearly outperforms it in energy efficiency. For office applications, browsing with dozens of tabs, document editing, and video conferencing, the performance is more than sufficient with the 16GB of LPDDR5 RAM.

Windows 11 Pro comes pre-installed with minimal bloatware, typical of MINISFORUM. Windows updates and AMD drivers are usually available through Windows Update. Some advanced users have successfully installed SteamOS/Bazzite to turn it into a living room console.

Indicative benchmarks (Ryzen 5 7545U):

🔌 Energy Consumption and Cables

The UM750L Slim is exceptionally efficient. It consumes approximately 13W at idle, and under maximum sustained load, it can reach 65-90W depending on the task. It comes with a 65W power supply  included, but thanks to the USB4 port with 100W PD, you can also power it from any compatible laptop charger.

This makes it ideal even for installations with limited power or on desktops where minimizing cabling is preferred. HDMI and DisplayPort cables are not included in the box, so you'll need to provide your own.

🌡️ Temperature and Noise (Actual Thermal)

The dual-fan cooling system with phase-change materials and dedicated heatsinks for the CPU, RAM, and SSD is one of the UM750L Slim's strongest features. MINISFORUM claims a 25% temperature reduction compared to single-fan systems, and in practice, the system remains quiet with a noise level below 35 dB during typical workloads.

Under sustained load tests (rendering, compilation), the CPU temperature can reach 70-80°C, which is completely normal for this type of laptop chip in a compact form factor. No cases of aggressive throttling have been reported during everyday use.

🔗 Connectivity and Extras

The UM750L Slim offers very complete connectivity for its size:

Front panel:

• 2× USB 3.2 Gen2 Type-A (10 Gbps)

• 3.5 mm combo jack (headphones + microphone)

• Power button with LED

Rear panel:

• 1× USB4 40 Gbps (data + PD 100W input / 15W output + video Alt Mode)

• 2× USB 2.0

• 1× HDMI 2.1

• 1× DisplayPort 1.4

• 1× LAN RJ-45 2.5 GbE

• Wi-Fi 6E + Bluetooth 5.3 (internal M.2 2230 card)

⚠️ Does not include: NFC, fingerprint reader, SD slot, or visible Kensington security port.

🔧 Expansion and Upgrades

This is a crucial point to know before buying:

• RAM: The LPDDR5 memory is soldered to the motherboard and is not user-expandable. The maximum is 32 GB in the model that comes with it from the factory. If you need more than 16 GB, purchase that model directly.

• SSD Slot 1 (primary): M.2 2280 PCIe 4.0 x4 — up to 4 TB — read speeds up to 7,000 MB/s. User replaceable.

• SSD Slot 2 (secondary): M.2 2280 PCIe 4.0 x2 — up to an additional 4 TB — speeds up to 3,500 MB/s. Allows expansion to a total of up to 8 TB of storage.

• There is no 2.5" bay or support for additional HDD drives.

• The Wi-Fi card (M.2 2230) is theoretically replaceable if you want to upgrade the Wi-Fi module.

🆚 Comparison with Direct Competitors

The UM750L Slim falls short in graphics performance compared to the UM760 (the Radeon 760M has twice the number of Compute Units), but it gains in CPU modernity (Zen 4 vs. Zen 3+) and adds USB 4. For gaming, the UM760 is a better option at a similar price. For productivity and connectivity, the UM750L Slim excels.

💬 Reviews on Well-Known Pages

The reviews of the UM750L Slim are generally very positive, although with some important nuances:

🟢 Most praised aspects:

• The power LED is very bright.

🧪 Technical Tests

Based on analyses published by various media outlets and specialized YouTube channels:

CPU — Ryzen 5 7545U:

• The 4nm chip with 6 hybrid cores (2 high-performance Zen 4 + 4 efficiency Zen 4c) offers multi-threaded performance equivalent to a desktop Ryzen 5 5600X, with much lower power consumption.

• In PassMark Single-Thread it achieves ~3,755 points, 11% higher than the UM690L Slim with Ryzen 5 6600H.

• Ideal for code compilation, image editing, FHD video editing, and intensive multitasking.

RAM — LPDDR5 6400 MT/s Dual Channel:

• The dual-channel soldered memory at 6400 MT/s is significantly faster than the DDR4 of many competitors, especially benefiting the integrated GPU that shares bandwidth.

• Low latency thanks to the LPDDR5 standard.

Storage — PCIe 4.0:

• The main slot achieves read speeds of 6,700–7,300 MB/s in real-world testing, excellent for a compact device.

• The second slot, with PCIe 4.0 x2, reaches ~3,000–3,500 MB/s, also above many competitors with PCIe 3.0 slots.

Thermal under stress (Prime95 + FurMark):

• CPU temperatures under full load: ~75-82°C

• The system remains quiet even under maximum load thanks to the dual fan.

• Severe throttling is not detected under normal daily use.

🎮 Gaming and Emulation

The Radeon 740M GPU with 4 RDNA 3 CUs is the weakest link in this gaming rig. Here's a realistic guide to what you can expect:

🎮 Gaming PC (1080p):

🕹️ Emulation:

The Radeon 740M, while inferior to the 760M, is perfectly adequate for emulation up to PS2/Wii and casual/indie gaming. For smooth 1080p modern gaming, we would recommend opting for the UM760 with a Radeon 760M.

❓ Frequently Asked Questions (FAQ)

Can the RAM be upgraded?
No. The LPDDR5 RAM is soldered to the motherboard. If you need 32 GB, you must buy the model that comes with 32 GB pre-installed, which is the maximum supported.

Can I install Linux or SteamOS?
Yes. Several users have successfully installed SteamOS and Bazzite, although some drivers may require additional configuration.

Can a 2TB or 4TB SSD fit in each slot?
Yes. Each M.2 slot supports up to 4TB, for a maximum total of 8TB of storage.
