The total system output is 126 TOPS. It provides powerful parallel computing capabilities for demanding AI workflows. It is ideal for running local LLMs, multimodal models, and computationally intensive tasks
- 128GB UMA MemoryEquipped with up to 128GB of LPDDR5x-8000MT/s unified memory, it enables the CPU and GPU to access a shared, high-bandwidth memory pool with extremely low latency. Ideal for large-scale AI inference, 3D workloads, and complex timelines in video editing. It eliminates traditional VRAM bottlenecks, ensuring smoother data transfer during high-intensity computations. The UMA design maximizes performance stability under high loads
- Flexible ExpansionThe MS-S1 MAX features USB4 V2 (up to 80Gbps), dual 10GbE LAN, HDMI 2.1 (up to 8K60), a full-length PCIe x16 expansion slot, and dual M.2 slots supporting up to 16TB RAID 0/1. Wi-Fi 7 provides stronger signal coverage and a more stable wireless experience. The slide-out design facilitates upgrades and maintenance. It easily adapts to personal, studio, or rack-mount enterprise environments
- High-Efficiency Cooling SystemUtilizing an aerospace-grade aluminum alloy chassis, copper base plate, six heat pipes, dual turbine fans, and advanced PCM thermal conductive material, it maintains stable cooling performance even under continuous load. This system supports 130W continuous power and 160W peak power operation, with a built-in 320W power supply. It boasts multiple global certifications including CCC, FCC, UL, CE, and UKCA, ensuring stable and reliable operation in various environments
- Cluster DesignTwo MS-S1 MAX units can be configured as a dual-unit cluster to run a large 235B Q4 model locally, achieving an output speed of 10.87 tok/s. Supporting 2U rack deployment, multiple MS-S1 MAX units can be cascaded into a distributed cluster to create a high-efficiency AI computing center. A cluster of four MS-S1 MAX units successfully ran a DeepSeek-R1 671B Q4 large model. A reserved cluster power-on interface allows for unified start-up and shutdown
- Multi-Scenario Workflow DesignBuilt-in dual DMIC AI noise-canceling microphones support mainstream AI models and can clearly capture voice commands. Four switchable modesperformance mode, balanced mode, silent mode, and rack modeflexibly adapt to various application scenarios from personal desktops to enterprise clusters

Size: MS-S1 Max-128/2TB
First you should know I am a huge fan of Minisforum. I own many Minisforum mini PCs because I find them unique, well made and a great value. With that out of the way, when I saw the MS-S1 MAX announced, my jaw about hit the floor! I've never seen a Minisforum mini PC this powerful or expensive. However, when looking at all the specifications, the cost to build my own alternative with similar specs is much more costly. To put it simply, this is the single most powerful computer I have ever owned. It basically does everything from being a powerful workstation to even AAA gaming. The fact it has USB4 v2 on it is icing on the cake. USB4 v2 can move data at 80gbps! Plus there are two addition USB4 ports (not v2). There are also 4 USB I don't yet have any external devices that can take advantage of that, so it's a nice change of pace to get ahead of the technology rather than just keeping up or catching up later. Of course it has USB 3.2 on the front (one) and two more in the back, along with 2 more USB 2 in the back as well! Talk about connectivity options! While it has a single HDMI out, each of the USB4 ports can be used as a Display Port video output, for a total of 5 monitors in use at the same time! All can independently support video resolutions of 8K@60Hz or 4K@120Hz! Imagine getting a car that is fully loaded with every feature and every bit of performance possible. That's what this is in the computer world. two 10Gbe eithernet networking, Wi-Fi 7, a 16 core, 32 thread CPU with 125+ TOPS for AI processing. It comes with 128GB of RAM already installed, along with a 2TB NVMe Gen 4 x 4 NVMe storage drive. There is a spare NVMe slot to add a second storage drive, but it does run a Gen4x1 (just fyi). Did I mention it has a built-in 320 watt power supply? No external bricks or adapters to worry about! And the cooling system is insane. This thing just stays whisper quiet and runs cool regardless of what workloads I throw at it! It has a full-length PCIe4x16 slot for a low profile add-in card option (though it runs at PCIe 4 x4). Windows 11 Pro is pre-installed and activated. Scanned for any spyware or malware and it is 100% clean and bloat-free! Talk about you get what you pay for! This thing is an absolute beast of a computer, let alone a mini PC. Am I happy with it? What do you think? In the words of Ferris Bueller, "If you have the means, I highly recommend picking one up."

This is a unicorn with the 128gb of unified memory architecture. With this you can easily run 70 billion parameter LLMs. The ports coverage is ahead of its time with 80gb usb-c and 10gb ethernet.

Excellent, high-performance mini PC. However, be aware that it requires a wired mouse for the first-time setup; Bluetooth and wireless dongles (like the Logitech MX series) didn't kick in until after I was finished with the install.

It works. The unified memory does allow for running large models. It is slow as molasses for anything over 70b parameters and I had to install Linux to make the pc properly take advantage of the video card. On paper this looks like an amazing computer, but between the bus speed and the heavily restricted bios, I have greatly regretted buying this computer. I should have saved another $1000 and gotten an Nvidia DGX spark like I initially planned. Every time I use this with my local models it makes me sad.

I needed a portable computer to bring to parties and friends houses to play video games. Instead of carrying around a really heavy desktop I use this machine instead. I paired it with a 3050 6gb card that I was using with a 6th gen i5 and the performance difference is huge. I will eventually buy a 4060 or 5060 to put inside... I wasn't expecting the power supply to have a spare 8 pin coming from the power supply but I appreciate it.

I bought the barebones 129i7 because I already had memory and a M.2 drive that would work with it. I wanted a small machine that had a slot for a half height video card so I could use for simple Solidworks drawings. When I got it all set up this little machine is really fast and is going perfect for what I want to do. I have two small complaints: Minisforumn does not make it easy to find the drivers for this machine and the little metal bracket to incase the wifi/bluetooth card (not included but I also had a spare) is difficult to work with. I finally gave up and didn't use it.
