Bmax B9 Power

Manufacturer: Bmax

The Bmax B9 Power is a compact Mini PC built around a Micro-ATX form factor, measuring just 126 × 52 × 112 mm with a total volume of 733.824 cm³. It pairs a laptop-class processor with 24GB of DDR5 memory running at 4400 MHz, alongside a 1TB NVMe SSD for storage. The system supports up to 64GB of RAM across two memory channels, and the CPU leverages big.LITTLE architecture with 14 cores — six performance cores at 2.5 GHz and eight efficiency cores at 1.8 GHz — reaching a turbo frequency of 5 GHz across 20 threads.

Graphics are handled by the integrated Iris Xe Graphics 96EU, which includes 768 shading units, 48 TMUs, and 24 ROPs, with a turbo clock of 1450 MHz and support for up to four simultaneous displays via two HDMI 2.1 ports and one DisplayPort output. Connectivity options include Wi-Fi 6, Bluetooth 5.2, two USB 3.2 Gen 2 Type-A ports, one USB 3.2 Gen 2 Type-C port, two USB 2.0 ports, and a 3.5 mm audio jack. On the performance side, the unit scores 26897 in PassMark multi-core and 11894 in Geekbench 6 multi-core testing, and it carries a one-year warranty.

Pros
  • Supports up to four simultaneous display outputs through two HDMI 2.1 ports and one DisplayPort, making it suitable for multi-monitor setups

Cons
  • No RJ45 port means wired Ethernet connectivity is not available directly from the unit
  • The clock multiplier is locked, offering no option for frequency adjustments
  • ECC memory is not supported, which limits use in error-sensitive or reliability-critical environments
  • Only two USB 2.0 ports and a single USB-C port may feel limiting for users with multiple peripherals
  • No Thunderbolt 3 or 4 ports, excluding high-bandwidth external device options that rely on those interfaces
  • Covered by only a one-year warranty period
Who is this for?

This Mini PC suits users who need a compact, multi-display workstation for productivity tasks such as office work, content consumption, or light creative workflows, thanks to its four-display output capability and DDR5 memory with up to 64GB expandability. It also works well for home theater setups or living room PCs given its small footprint and dual HDMI 2.1 outputs. Those who rely on wireless connectivity will appreciate the Wi-Fi 6 and Bluetooth 5.2 support, and the 1TB NVMe SSD makes it a practical daily driver where fast storage access and reasonable multitasking headroom matter.

Who is this NOT for?

Users who require dedicated graphics performance for gaming, 3D rendering, or GPU-accelerated workloads will find the integrated Iris Xe Graphics 96EU insufficient for demanding visual tasks. The absence of an RJ45 port makes it a poor fit for environments where wired network reliability is essential, such as server rooms or professional network-dependent setups. Additionally, the locked clock multiplier and lack of ECC memory support mean it is not appropriate for overclocking enthusiasts or anyone running error-sensitive computing tasks that require memory integrity assurance.
