Detailed Insights into the Bmax B9 Plus
The Bmax B9 Plus showcases thoughtful engineering in its compact chassis, measuring just 5.04 x 4.41 x 1.77 inches and weighing under a pound. The build quality is solid for its price point, with a clean aesthetic that won’t look out of place in a professional setting. Port selection is excellent — you get two HDMI 2.1 ports, one DisplayPort 1.4a, and a USB-C that supports DisplayPort Alt Mode, enabling triple 4K display configurations. The inclusion of VESA mount hardware means you can tuck this mini PC behind a monitor for an impressively clean desk setup.
Performance from the Intel Core i5-1250P is genuinely impressive for a machine this size. The processor’s 12 cores (4 performance cores, 8 efficiency cores) and 16 threads, combined with the fast LPDDR5 RAM, deliver smooth multitasking even under heavy loads. According to reviews, the system handles 60+ browser tabs alongside productivity applications like Word, Excel, Zoom, and Spotify without any noticeable slowdowns. The PassMark CPU score of 17,649 puts it comfortably ahead of many competing mini PCs in this price range, and the cooling system manages to keep temperatures in check without producing distracting noise.
Connectivity and expansion options are comprehensive for a mini PC of this size. Beyond the display outputs, you get two USB 3.2 ports, two USB 2.0 ports, a USB-C port, and a Gigabit Ethernet jack. WiFi 6 (802.11ax) and Bluetooth 5.2 provide modern wireless connectivity. For storage expansion, there’s an available M.2 2280 slot alongside the primary drive, plus a 2.5” SATA bay that can accommodate up to 2TB of additional storage. The main limitation is the soldered 24GB LPDDR5 RAM — while generous, you can’t upgrade it if your needs grow.
Reviewer Insights on the Bmax B9 Plus
Click To Cart’s Perspective
Click To Cart describes the B9 Plus as “a very practical, modern, and space-saving solution” ideal for office work, students, and remote professionals. The review highlights the compact form factor and lightweight design at approximately 400 grams, noting that the “Space Capsule” cooling system keeps the machine whisper-quiet during normal operation. Gaming tests at 1080p showed respectable results for integrated graphics: League of Legends at 108 FPS, Dota 2 at 85 FPS, Street Fighter 4 at 90 FPS, and Resident Evil at 72 FPS.
The reviewer emphasized the triple 4K display support as a standout feature, with the combination of HDMI 2.1, DisplayPort 1.4a, and USB-C providing flexibility for multi-monitor setups. However, they noted that the integrated Iris Xe graphics means this isn’t a machine for heavy gaming or 3D work — it’s firmly positioned as a productivity powerhouse rather than an entertainment center.
MiniPC-Review.com
According to MiniPC-Review.com, the B9 Plus delivers “outstanding performance for its size” and represents an “excellent alternative to desktop PC for professional/office use.” Their testing confirmed the system “remains virtually silent, even during demanding tasks” while maintaining safe temperatures without thermal throttling. They noted that the 24GB of LPDDR5 RAM enables smooth multitasking with multiple applications running simultaneously.
The review particularly praised the productivity performance, stating there’s “very smooth multitasking experience with the i5-1250P processor” and calling it a “perfect replacement for a large desktop computer.” User ratings across e-commerce platforms consistently fall between 4 and 4.5 stars, with quiet operation and stable performance being the most frequently cited positives. The main criticisms centered on the non-upgradeable RAM and limited gaming capabilities.
Customer Reviews of the Bmax B9 Plus
Amazon customers have given the Bmax B9 Plus a solid 4.6 out of 5 stars based on 58 reviews, reflecting generally positive experiences with the mini PC. Buyers frequently praise the compact size and quiet operation, with many noting they can barely hear the fan during normal use. The performance for everyday tasks and productivity work receives consistent approval, with users reporting smooth operation for web browsing, office applications, and video streaming.
Common complaints center around expectations versus reality. Some customers expected more gaming capability than the integrated graphics can deliver, while others were surprised by the non-upgradeable RAM configuration. A few reviewers mentioned that certain versions arrived without Windows pre-activated, requiring purchase of a license separately. Despite these minor issues, the consensus is that the B9 Plus delivers excellent value for its price point in the productivity mini PC category.
The 24GB RAM configuration receives particular praise from users who multitask heavily, with several reviewers noting they can run complex workflows with dozens of tabs and multiple applications without performance degradation. The triple display support has also won fans among professionals who need extensive screen real estate for their work.
Conclusion
The Bmax B9 Plus is an excellent choice for anyone seeking a powerful, compact mini PC for productivity tasks, home office work, or as a space-efficient desktop replacement. The Intel Core i5-1250P processor with 12 cores provides genuine computing power in a package that weighs less than a pound, while the 24GB of fast LPDDR5 RAM ensures smooth multitasking. Triple 4K display support makes it particularly attractive for professionals who rely on multiple monitors, and the near-silent operation means it won’t distract during focused work sessions.
However, prospective buyers should be aware of its limitations. The soldered RAM means 24GB is all you’ll ever have, so if you anticipate needing more memory in the future, this isn’t the right choice. Similarly, gamers looking for AAA gaming performance should look elsewhere — while the Iris Xe graphics can handle esports titles at respectable frame rates, demanding 3D applications and modern games will struggle. The B9 Plus is fundamentally a productivity machine, and it excels at that role.
At $359.99, the Bmax B9 Plus offers compelling value for its target audience. The combination of a 12-core processor, generous RAM, fast NVMe storage, and comprehensive connectivity makes it a solid investment for home offices, media centers, or anyone who needs desktop performance without the desktop footprint.
