๐จ Design and Construction Quality
BMAX B5A Pro mini PC
The BMAX B5A Pro features an all-black casing with a metallic finish on the top cover, giving it a serious and understated look. The side vents are well-placed to optimize airflow. The chassis is compact—comparable to the size of a DVD case—and the build quality is solid: no noticeable flex or creaking.
The design has an industrial feel with modern touches, blending discreetly into any workspace or living room. It includes a VESA mount in the box for direct mounting behind the monitor, ideal for minimalist desks. Overall, it conveys a sense of professionalism and sturdiness for its price range.

๐ฅ๏ธ Screen and Multimedia
The BMAX B5A Pro doesn't include a screen, but its video output system is one of its biggest strengths. Thanks to the combination of HDMI 2.1, DisplayPort 1.4, and USB-C with video support, it allows you to connect up to three monitors simultaneously at 4K/60Hz with HDR support.
Multimedia performance is excellent for its class: it plays 4K video without stuttering, supports H.264 and H.265 hardware decoding, and effortlessly handles platforms like Netflix, YouTube 4K, and Plex. For an HTPC in the living room or a multi-monitor desktop setup, this device stands out significantly against rivals with only one 4K output.

โก Performance and Software
Mini computer cooling system
The AMD Ryzen 7 5825U (or 5700U) processor is the same 8-core chip found in premium laptops from well-known brands. Documented real-world benchmarks show:
-
Cinebench R23 Single-Core: ~1,200–1,300 points
-
Cinebench R23 Multi-Core: ~9,000–10,500 points
-
CrystalDiskMark (SSD NVMe): Reads ~2,800–3,200 MB/s, Writes ~1,800–2,200 MB/s
-
3DMark Fire Strike (Vega 8 GPU): ~2,700–3,200 points
The "Space Capsule" cooling system — with dual heat pipes, turbine-type main fan and additional auxiliary fan — raises the TDP from 15W to 45W, with a performance improvement of 15-25% compared to conventional cooling systems in mini PCs of this category.
Windows 11 comes pre-installed and activated. It may include some additional apps that can be easily uninstalled, and Windows updates work normally.

๐ Energy Consumption and Cables
The BMAX B5A Pro includes an external power supply. Typical power consumption is around 15-25W, and can reach 40-45W under maximum load. It is a very energy-efficient device: its annual energy consumption under heavy use is a fraction of that of any conventional desktop PC. The power cable is standard and compatible with European plugs.
๐ก๏ธ Temperature and Noise (Actual Thermal)
The "Space Capsule" system integrates a main turbine-type fan, two copper heat pipes, and a secondary auxiliary fan, which sets this model apart from other mini PCs in the same category. During office use, CPU temperatures remain between 45-55°C with a virtually imperceptible noise level. Under sustained load, the CPU can reach 75-80°C with the fans at higher speeds, generating an audible but tolerable hum.
Thanks to its dual ventilation system, the B5A Pro maintains stable performance during long sessions without thermal throttling, which is especially appreciated during rendering tasks or extended gaming sessions.
๐ Connectivity and Extras
The BMAX B5A Pro has the following ports:
Front panel:
-
2× USB-A 3.2 Gen 1
-
1× 3.5 mm combo audio jack
Rear panel:
-
1× HDMI 2.1 (4K/60Hz, HDR)
-
1× DisplayPort 1.4 (4K/60Hz)
-
1× USB-C (data + 4K video)
-
2× USB-A 2.0
-
1× Gigabit Ethernet RJ45
Wireless:
-
WiFi 5 dual-band (2.4 GHz / 5 GHz)
-
Bluetooth 5.0
For the vast majority of home and professional uses, the connectivity is more than sufficient. WiFi 5 offers real speeds of up to 300-400 Mbps, suitable for 4K streaming, video calls, and remote work without any issues.

๐ง Expansion and Upgrades
One of the great advantages of the BMAX B5A Pro is its expandability:
-
RAM: 2 SODIMM DDR4 slots. Comes with 1 x 16 GB in single-channel configuration. Adding a second identical module activates dual-channel, with up to 25% more graphics performance. Supports up to 2 x 32 GB = 64 GB total.
-
Primary SSD: M.2 NVMe slot. Replaceable with any compatible drive up to 2 TB (WD Blue SN580, Samsung 970 Evo Plus, etc.).
-
Secondary drive: โ Includes SATA slot for 2.5" SSD/HDD drive, ideal for adding 1-2 TB of extra storage at no additional cost to the chassis.
