This new Minisforum workstation with Ryzen AI Max+ 395 looks small yet sneaks into racks with massive power

Minisforum MS-S1 Max introduces rack compatibility into the compact mini PC category
Memory bandwidth of 256GB/s supports handling extremely large AI workloads locally
Dual 10 Gigabit LAN ports provide networking speed uncommon in compact systems

Minisforum has unveiled the MS-S1 Max, a new system that joins the growing list of products built around AMD’s Strix Halo platform.

This device is a high-end option for professionals, supporting up to the Ryzen AI Max+ 395 processor along with as much as 128GB of LPDDR5x-8000 memory.

The memory runs in quad-channel mode with a bandwidth rated at 256GB/s, a figure sufficient for intensive workloads such as running large language models with more than 100 billion parameters locally.

A mini PC designed for both desk and rack

According to the company, the MS-S1 Max “scales from desktop to 2U rack.”

This phrasing leaves some ambiguity, since it is unclear whether different case options will be offered, or whether the desktop enclosure has been sized to slide directly into a rack without alteration.

Either way, the form factor is atypical for a mini PC, blurring the lines between compact desktop use and data center adaptability.

The MS-S1 Max incorporates a PCIe x16 slot inside the chassis, opening the door to discrete graphics cards or other expansion hardware.

This is a clear difference from many compact systems that lack internal upgrade paths.

Rear I/O includes one USB4v2 Type-C port with 80Gbps throughput and 15W USB-PD output, two additional USB4 Type-C ports at 40Gbps, four unspecified USB-A ports, dual 10 Gigabit LAN, and one HDMI output.

On the front, two more USB-C ports, a USB-A port, a headphone jack, and dual microphones are present.

Wireless connectivity extends to WiFi 7 and Bluetooth 5.4, reflecting current-generation standards.

Instead of relying on an external brick, this business PC integrates a 320W internal power supply.

This choice simplifies rack mounting and reduces clutter when used as a desktop.

There is no information on its cooling system, but considering its size, it should fit one for sustained workloads.

For workstation tasks involving AI model inference, video rendering, or multitasking, such a setup may prove advantageous if the thermal design is sufficient.

The company has not provided pricing or availability for the MS-S1 Max. Without those details, it remains difficult to judge how compelling this mini PC will be compared to rival offerings.
