Minisforum has locked in the global release date for its new powerhouse: the MS-S1 Max. This high-spec mini-PC, packed with up to 128 GB of RAM and the Ryzen AI Max+ 395 chip, steps into the spotlight this week.

MS-S1 Max mini-PC brings full-scale desktop power

Built for heavy-duty performance, the MS-S1 Max isn’t your average compact machine. It includes a PCIe 4.0 x16 slot and a pair of USB V2 ports pushing 80 Gbps each, yes, eighty. On paper, it outpaces most desktops in the same size category, and now it’s getting a proper worldwide debut.

Minisforum first teased the MS-S1 Max in China, later showing it off at IFA 2025 in Berlin. Now, it’s official: the global launch kicks off at 02:15 UTC on September 17. Pricing is still under wraps, but expect a premium tag. Comparable mini-PCs, like the EVO-X2, don’t exactly go light on your wallet either.

MS-S1 Max mini-PC offers dynamic power modes

A 320 W built-in power supply keeps the internals fed, but the real star is the 160 W PPT capability for the Ryzen AI Max+ 395. It’ll be available in multiple power modes depending on your needs:

• Performance: 160 W
• Balance: 130 W
• Quiet: 110 W
• Rack: 140 W

That flexibility makes the MS-S1 Max adaptable for both desktop workstations and server racks.

Ports galore in the MS-S1 Max mini-PC

This machine goes overboard in a good way on connectivity. On both front and back, you’ll find an array of ports ready for high-speed data, displays, and more.

Here’s the full list:

• 1x 3.5 mm audio jack
• 1x AC input
• 1x CMOS reset
• 1x HDMI 2.1 FRL (8K/60Hz)
• 1x Lock slot
• 2x RJ45 10G LAN (Realtek RTL8127)
• 2x USB 2.0 Type-A
• 3x USB 3.2 Gen 2 Type-A (10 Gbps)
• 2x USB4 (40 Gbps, DP Alt Mode, 15 W PD)
• 2x USB4 V2 (80 Gbps, DP Alt Mode, 15 W PD)

It’s not just impressive, it’s over-engineered in the best way.

Why MS-S1 Max mini-PC could reshape expectations

Few mini-PCs go this hard. Between its top-tier chip, massive RAM ceiling, and unfiltered port layout, the MS-S1 Max is pushing the boundaries of what compact machines can be. It’s built to compete with full desktops, and it doesn’t flinch.
