However, the glossy black surface on the front attracts fingerprints.

In addition, the large rubber pads on the bottom help to effectively dampen mechanical noise from fans or a 2.5-inch hard drive.


The accessories supplied by Beelink save further costs and make installation and use easier.

The scope of delivery includes a VESA mount including suitable screws, which allows the mini PC to be mounted directly behind the monitor.

For this type of mounting, a 20 cm long HDMI cable is included in the package, which can be used when the PC is attached to the monitor using a VESA mount.

In addition, a 95 cm long HDMI cable is included.

Cooling system

The Beelink Mini PC offers a powerful cooling system. A large cooler with heat pipes on the CPU draws air in from below and blows it out again at the rear of the case.

Additionally, there is a case fan on the top of the mainboard, which draws in fresh air from the side and directs it directly onto the mainboard, the RAM and the NVMe SSD.

A special heat sink in the motherboard cover is provided for the NVMe SSD, but the associated thermal pad is a little too small.

It should be noted that installing a SATA SSD can negatively affect the performance of the case fan.

Office performance

The Beelink Mini PC proves to be an ideal companion for everyday office and Internet applications, which are now largely done in the browser.

It offers high performance so that you can work without any restrictions. The mini PC almost always remains almost silent, which makes it suitable for quiet work environments.

Video streaming, YouTube, Netflix
Playing multiple video streams at the same time, for example from Netflix, YouTube and similar platforms, is easily possible. Playback on most platforms is supported by Intel GPU hardware acceleration, which helps reduce processor load.

The energy consumption is therefore lower; when using YouTube with hardware acceleration, the mini PC only uses 19 watts, while it needs around 25 watts without hardware acceleration.

In Geekbench, the Beelink SEi12 achieves performance values that are comparable to desktop processors such as the Intel Core i5-12400 or the AMD Ryzen 7 5800.

Content creation performance

Adobe Lightroom
The Beelink Mini PC's performance in Adobe Lightroom was tested with images up to 40 megapixels.

The mini PC responded promptly to editing commands and the use of tools such as spot removal/dust removal occurred without any noticeable delay.

You can also work easily with Blender or similar tools thanks to the high CPU performance.

The only limitation is the rendering of the images, where you have to be a little more patient as GPU acceleration is not available here.

Video editing
The mini PC also proved to be powerful in the area of video editing with Davinci Resolve.

Exporting the videos is done by the CPU, which works quickly thanks to its high number of cores. If you want to convert videos, you can also use the hardware acceleration of the integrated GPU with the Handbrake tool. This is many times faster and also more energy efficient.

Encoding Method resolution Frames per Second (fps)
QSV H265 720p 500
QSV H265 1080p 300
CPU X265 Fast 720p 180
CPU X265 Fast 1080p 90

However, it should be noted that with such computationally intensive tasks, CPU utilization can reach almost 100%. If the Intel CPU is busy, the two integrated fans also become audible to remove the heat from the case.

Gaming performance

When testing gaming performance, we focused on the Oxygen Not Included game.

Here it turned out that the CPU performance with a clock speed between 2.2 and 3.2 GHz is the limiting factor. Nevertheless, the mini PC delivers solid results:

  • With a "late game" save in Full HD, the PC achieves a frame rate of 30 FPS.
  • With a new game in Full HD, the frame rate is a stable 60 FPS, with the GPU being utilized at 64%.
  • In QHD resolution, the PC achieves 50 FPS with a GPU utilization of 90%.
  • At 4K resolution, the frame rate drops to 30 FPS while the GPU is at 100% utilization.

These results show that the Beelink Mini PC is quite suitable for casual gaming, especially at lower resolutions.

However, when it comes to more demanding gaming scenarios or higher resolutions, we reach the limits of its hardware.

Aztec Ruins High Tier Offscreen 34.4 35.5
Aztec Ruins Normal Tier Offscreen 97.1 99.5

GFXBench was used as a reference for gaming performance. The i7's integrated GPU in the Beelink Mini PC has 50% higher performance than the integrated GPU of a Core i9-14900K. The performance of this integrated graphics card is between a GeForce GT 1030 and an Nvidia T400. The overall performance of the integrated graphics card can therefore be classified in the entry-level range.

The performance of the Wi-Fi adapter was tested with a Cudy X6 router. At a distance of 5 meters, the mini PC achieved a very good bandwidth of 750 Mbps in the speed test.

When using a network share, a stable transfer rate of approximately 65 MB/s was achieved.

The Realtek Gigabit LAN adapter consistently achieves maximum speed.

Noise Level

Even though the Beelink Mini PC is never completely silent, it still impresses with its low noise level under various conditions.

The device remains almost inaudible during low or brief periods of high loads.

This feature makes it unobtrusive in a quiet work environment.

Interestingly, the mini PC remains relatively quiet, but still audible, even under high load.

Thanks to its powerful cooling system, it is often quieter than comparable Intel systems, such as notebooks or other mini PCs.

The mini PC is suitable for users who value a quiet workplace.

Expandability and connection options

The Beelink Mini PC offers outstanding expansion options for its size. RAM, NVMe SSD, SATA hard drive, WiFi adapter and power supply can be exchanged or expanded.

This makes it possible to install a combination of an 8TB SATA SSD and an NVMe SSD.

According to Intel-Ark, the RAM can be expanded up to 64GB, making the mini PC also suitable for more demanding tasks.

Selection of components

In terms of usage, the choice of components makes the Beelink Mini PC a well-balanced office PC.

The high-clocked RAM complements the Intel Core i7-12650H well, which is crucial for both high multicore and graphics performance.

The WLAN adapter supports all important standards with WLAN 6 and also offers Bluetooth 5.2 support.

Crucial 32GB DDR4 RAM with 3200MHz

The Crucial P3 Plus NVMe SSD with QLC storage is optimal for most office applications. Limitations in speed only become apparent when the SSD fill levels are high and during extensive copying processes involving several gigabytes.

In such cases, the transfer speed can drop to an average of around 100 MB/s. This effect is not yet noticeable with smaller copy processes in the 1-5 GB range or with benchmarks.

Power consumption

We tested the energy consumption of the Beelink Mini PC on both Windows and Linux (with a desktop interface).

It was noticeable that the power consumption in desktop operation under Windows is significantly higher than under Linux.

Interestingly, switching from an NVMe SSD, which comes standard, to a SATA SSD results in a saving of around 2 watts.

Power consumption under Windows

  • In desktop operation: approx. 16 watts
  • When using the browser actively: around 22 watts
  • During video conversion: about 80 watts

Power consumption under Linux:

  • In desktop operation: approx. 9 watts (with 'powertop --auto-tune': 7.5 watts)
  • When using the browser actively: around 16 watts
  • During video conversion: approximately 80 watts

The power consumption is typical for a current Intel system and therefore brought no surprises.

Under Windows, power consumption can be influenced primarily by the three different energy saving modes, especially in desktop operation (without load). Consumption drops to 16 watts in desktop operation in energy saving mode, while the system requires 26 watts in “high performance” mode.

However, in programs with high performance requirements, the thermal performance of the cooling system limits the electrical power consumption, which limits the clock speed of the Mini PC.

However, this is not unusual behavior for an Intel or AMD system; only Apple systems with their own SoC perform better here.
