📦 Unboxing and Box Contents

The MS-A2 arrives in a sturdy, double-walled cardboard box. Inside you will find:

• Mini PC MINISFORUM MS-A2

• External power adapter 240W (19V/12.63A)

• Power cable

• VESA adapter for rear monitor mounting

• Multilingual Quick Start Guide

• Screws for SSD installation

The first impression upon taking it out of the box is striking: it weighs more than expected for its size, which conveys a sense of solidity. The matte black finish with visible ventilation grilles on all sides makes it clear that this is no ordinary home mini PC.

🔧 Key Technical Specifications

🏗️ Design and Construction Quality

Minisforum MS-A2 rear ports 

The MS-A2 uses a chassis very similar to that of the popular MS-01, with a high-density plastic and metal finish that feels solid to the touch. Its dimensions of 196 × 189 × 48 mm place it in the "small form factor" category rather than ultra-compact, but it remains perfectly manageable on a desk or mounted behind a monitor using the included VESA mount.

Access to the interior is the most noteworthy design feature: a single rear latch releases the cover without tools, greatly simplifying the installation of RAM and SSDs. Ventilation grilles run along all sides of the device—top, bottom, and sides—maximizing airflow. The rear panel is where the most visual information is located: four Ethernet ports, HDMI, two USB-C ports, two USB-A ports, and the PCIe expansion slot, all labeled in a way that could be improved, according to the reviewers themselves.

One area for improvement noted by several sources is the lack of clear labels on USB ports to distinguish speeds (Gen1 vs. Gen2) and on RJ45 ports to identify the Intel vs. Realtek controller, which matters if you manually configure drivers in Linux.

🖥️ Screen and Multimedia

The MS-A2 has some of the most capable video outputs on the market in this segment.

The two USB-C outputs and the HDMI 2.1 output allow you to connect up to three monitors simultaneously, with support for up to 8K@60Hz or 4K@144Hz on each one.

This makes it a serious option for multi-monitor workstations: graphic designers, video editors, or traders can connect their setups without needing an additional graphics card for non-3D use. However, it's important to clarify that the USB-C ports are USB 3.2 Gen2 at 10 Gbps, not USB4 or Thunderbolt, which limits the use of external eGPUs via that connection.

For audio, it has a 3.5mm combo jack (input/output) on the front panel, without a separate advanced HDMI audio output. For audio production, an external USB DAC will suffice.

⚙️ Performance and Software

The Ryzen 7 7745HX (8 cores/16 threads, Zen 4, up to 5.1 GHz) delivers excellent performance for multithreaded tasks: code compilation, virtualization, 3D rendering, 4K video editing, and light machine learning. In the variant with 32 GB of DDR5 RAM and a 1 TB NVMe SSD that we reviewed here, the system is completely smooth under intensive multitasking.

The MS-A2 with Ryzen 9 (higher model) achieves the following in published benchmarks:

⚠️ Important note: SSD write speeds showed some inconsistency during extended testing in several independent reviews, something to keep in mind in write-intensive workflows.

The MS-A2 is sold without an operating system in the barebones version. Minisforum also offers versions with Windows 11 Pro pre-installed. It works perfectly on Linux (Ubuntu, Debian, Proxmox), although it requires installing three different drivers for the four network ports (Intel i226-V, Realtek RTL8125, and Intel X710).

🔌 Energy Consumption and Cables

The MS-A2 includes an external 240W (19V/12.63A) power supply, a rather bulky component compared to other mini PCs on the market. The actual power consumption measured in tests is:

For an 8-core PC with dual 10G connectivity, these numbers are reasonable. However, compared to a conventional mini PC used for office tasks (10-15W idle), you have to expect higher energy costs for 24/7 operation.

🌡️ Temperature and Noise (Actual Thermal)

The MS-A2's cooling system is one of its strongest features: three pure copper heatpipes, phase-change thermal compounds, and turbo fans that increase airflow by 30% compared to conventional designs. The reactor-type direct extraction design keeps temperatures under control even during continuous 24/7 operation.

Actual temperature data recorded in sustained load tests:

Regarding noise: 36–38 dB at rest and 41–43 dB under load, which puts it at an acceptable level for the office, although noticeably more audible than a fanless or low-power mini PC.

⚠️ Attention: If you plan to stack multiple MS-A2s in a home rack or homelab, be aware that the top and bottom vents can transfer heat between adjacent units.

🔗 Connectivity and Extras
