7. Performance

The AMD Ryzen 5 7545U processor with Radeon 760M integrated graphics delivers strong performance for daily computing and demanding applications.

• Multitasking: Capable of handling numerous browser tabs, multiple 4K video streams, and office applications simultaneously without significant lag.
• Content Creation: Suitable for photo editing in applications like Photoshop and light 1080p video editing in software such as DaVinci Resolve.
• Storage Speed: The PCIe 4.0 SSD provides fast read speeds (around 6000 MB/s) and write speeds (around 5300 MB/s), ensuring quick system response and data transfers.

8. Gaming Performance

While not a dedicated gaming desktop, the integrated AMD Radeon 760M GPU offers respectable gaming capabilities for its class.

• Emulated Games: Classic emulated titles like Mario Kart and Smash Bros run smoothly at 60 FPS.
• Casual Games: Games like Stardew Valley run flawlessly with minimal system load.
• Demanding Titles:
  • Grand Theft Auto V (Enhanced Edition): Achieves 50-60 FPS at 2K resolution on low settings, and can maintain playable frame rates (around 30-40 FPS) even on high graphics settings at 2K.
  • Forza Horizon 5: Runs at 60-70 FPS at 2K resolution on low settings. Dropping to 1080p can yield over 60 FPS, potentially closer to 80 FPS.
  • Hogwarts Legacy: Playable at 30-40 FPS at 2K resolution on lowest settings.
• External GPU Support: The USB4 port allows connection to an external GPU (eGPU) enclosure, significantly boosting gaming performance to desktop-class levels. For example, with an eGPU, Grand Theft Auto V can run at 2K high graphics at 60 FPS, and Forza Horizon 5 can achieve over 80 FPS at 2K on high settings with FSR3.

9. Thermal Management, Noise & Power Consumption

The UM750L Slim features an efficient active heat dissipation system to maintain stable operation.

• Thermal Performance: During stress tests (e.g., AIDA64 for 22 minutes), the CPU temperature typically ranges from 83-85°C, with peaks at 91°C under heavy load. This is within acceptable operating limits.
• Noise Levels: The cooling system operates quietly. At full load, the fan noise hovers around 35 decibels, which is a smooth hum rather than a high-pitched whine. At idle, the device is nearly silent.
• Power Consumption:
  • Idle: Approximately 6 watts, making it highly energy-efficient for low-power tasks.
  • Sustained Load: Around 60 watts during prolonged heavy use.
  • Peak Load: Maximum recorded power draw is 70 watts.

10. Maintenance

• Driver Updates: Regularly check for and install the latest drivers from the MINISFORUM official website to ensure optimal performance and compatibility. This is especially important after reinstalling the operating system.
• Dust Removal: Periodically clean the vents and internal components (if comfortable opening the device) to prevent dust buildup, which can affect cooling efficiency.
• Software Updates: Keep your operating system and applications updated to benefit from the latest features, security patches, and performance improvements.

11. Troubleshooting

• No Display:
  • Ensure all display cables (HDMI, DP, USB4) are securely connected to both the Mini PC and the monitor.
  • Verify the monitor is set to the correct input source.
  • Try connecting to a different display port or monitor.
• Power Issues:
  • Check that the power adapter and cable are securely connected to both the Mini PC and the power outlet.
  • Ensure the power outlet is functional.
• Slow Performance:
  • Close unnecessary applications running in the background.
  • Check for sufficient free storage space on your SSD.
  • Ensure your drivers and operating system are up to date.
• BIOS Issues: The BIOS is standard UEFI. If the system is stable, it is generally recommended to avoid BIOS updates unless specifically instructed by support or to address a known issue.
• Clear CMOS: If you encounter boot issues or incorrect BIOS settings, use the Clear CMOS button on the front panel to reset BIOS settings to default.
