Minsforum MS-S1 Max Review – Who Is This For???

Ever Wanted a Modern Mac Mini, but Windows? And for AI? The MS-S1 Max Review

The Minisforum MS-S1 Max is one of those mini workstations that looks straightforward on paper, but starts to feel unusual once you look at how it is put together and who it seems to be aimed at. It is built around AMD’s Ryzen AI Max+ 395, pairing a 16C/32T CPU with Radeon 8060S integrated graphics and an NPU that contributes to a quoted platform total of up to 126 TOPS. The big differentiator is the memory design: 128GB of LPDDR5x-8000 UMA, shared between the CPU and GPU, which changes the usual limits you hit on iGPU systems where VRAM is the first bottleneck. Minisforum also leans into “serious deployment” features here, including dual 10GbE, WiFi 7, USB4 v2, a slide-out chassis for maintenance, and even references to clustering and 2U rack mounting. The result is a machine that can make sense for creators, power users, and AI-focused workloads, but it also comes with a price level that forces the obvious question: what are you actually getting for that money beyond raw specs.

Minisforum MS-S1 Max Review – Quick Conclusion

The Minisforum MS-S1 Max is best understood as a compact Strix Halo workstation rather than a conventional mini PC, because its value is tied to the Ryzen AI Max+ 395 APU, the Radeon 8060S iGPU, and especially the 128GB LPDDR5x-8000 UMA memory pool that helps avoid the usual iGPU VRAM ceiling in creation, GPU-accelerated work, and local AI experimentation. It pairs that core platform with unusually strong external connectivity for its size, including dual 10GbE RJ45, WiFi 7, and a mix of USB4 and USB4 v2 ports that make high-bandwidth docks and storage setups practical, while the internal 320W PSU and heavy cooling stack are clearly built for sustained loads rather than short bursts. In testing, the system’s behavior has a few quirks that matter in daily use, particularly the way the chassis can feel hot to the touch in idle until the fan profile becomes more reactive under load, and the fact that noise ramps into the low 50 dBA range once the cooling really gets going, even if idle acoustics are more modest. Expandability is also a mixed bag: the slide-out design is convenient, but the storage layout includes a PCIe 4.0 x4 M.2 slot alongside a second M.2 limited to PCIe 4.0 x1, and the PCIe x16 slot is PCIe 4.0 x4 electrically, so it rewards buyers who already know what they plan to add. The price is the real gatekeeper here, because it only makes sense if you will actually use the UMA memory capacity, the iGPU performance, and the high-speed networking and USB bandwidth, but for that narrower audience, it offers a rare combination of compact form factor, strong APU compute, and connectivity that is difficult to match without moving to a much larger desktop or adding a discrete GPU.

Minisforum MS-S1 Max Review – Design & Storage

The MS-S1 Max feels like Minisforum took the general “mini workstation” idea and then built a thicker, more industrial version of it to cope with the Strix Halo platform. The chassis is metal and noticeably more substantial than the smaller MS-series boxes, with ventilation cut across multiple sides rather than relying on a single intake and exhaust path. It can be used vertically or horizontally thanks to feet on more than one face, which makes sense given how much of the marketing leans toward desk use one day and rack or shelf use the next.

Minisforum also keeps the slide-out structure here, and it is clearly intended to make maintenance less annoying than a traditional small desktop. In practice, it is still a compact, dense build, but you are not dismantling the entire enclosure just to access the main service areas. The system also has a couple of physical touches that make it feel more “deployment aware” than most mini PCs, like the mounting points underneath and the general emphasis on stacking, shelving, or grouping more than 1 unit together.

Storage is one of the areas where the MS-S1 Max shows both its strengths and its compromises. You get 2 internal M.2 2280 slots, but they are not equal: 1 is PCIe 4.0 x4 and the other is PCIe 4.0 x1. That means you can have a fast primary NVMe for OS and active work, but the second slot is better treated as capacity storage, warm data, or a secondary pool where peak throughput matters less. Minisforum ships the reviewed configuration with a 2TB Gen 4 SSD, so you can start testing immediately, but once you begin planning expansion, that lane split becomes a real consideration.

Physically, the M.2 placement is functional but not especially convenient. The slots sit low in the chassis near the base and tucked behind a lot of the cooling hardware, which makes upgrades feel more fiddly than they need to be. There is airflow down there, but it is not the kind of open, easy-access layout you get in a larger desktop. It also does not really encourage tall, pre-fitted heatsinks on SSDs, since clearance is limited and the space around the cooling assembly is tight. If you plan to run heavy sustained writes, you will probably end up choosing low-profile drives or slim heatsinks simply because it is the easiest fit.

On the expansion side, the MS-S1 Max includes a full-length PCIe x16 physical slot, but it is PCIe 4.0 x4 electrically, and that matters if you are buying cards based on the x16 shape alone. The form factor also pushes you toward half-height, half-length cards in most practical installs, and even then it can get cramped depending on cabling and where the PSU wiring runs.

In other words, the slot is useful for NICs, storage adapters, capture cards, and some compact accelerators, but it is not a “drop in any x16 card” situation, and the system rewards planning ahead before you buy hardware for it.

Minisforum MS-S1 Max Review – Internal Hardware

At the heart of the MS-S1 Max is AMD’s Ryzen AI Max+ 395, and the main thing to understand is that it is an APU platform built to behave more like a compact workstation than a typical integrated-graphics mini PC. You are getting a 16C/32T Zen 5 CPU with boost up to 5.1GHz, paired with an on-die Radeon 8060S GPU with 40 CUs and up to 2900MHz. In real use, that combination shifts the expectations around what “no discrete GPU” actually means, because the compute and graphics capability are designed to scale together rather than feeling like a strong CPU with an afterthought iGPU.

The most defining hardware choice is memory, because you do not get SODIMM slots here at all. The system uses up to 128GB LPDDR5x-8000 on a 256-bit bus, and it is shared between CPU and GPU via UMA. That has practical implications in workloads that normally hit VRAM limits first, like GPU-accelerated creative work or local AI inference, where the ability to allocate a much larger pool to the GPU can matter more than raw shader count. It also means your “upgrade path” is basically decided at purchase, so the value proposition depends heavily on whether 128GB UMA is something you will genuinely use, rather than just admire on a spec sheet.

On the AI side, the platform is marketed around a combined figure of up to 126 TOPS, with the NPU itself rated up to 50 TOPS. In day-to-day terms, that does not automatically translate into every app running faster, because it depends on whether your software actually targets the NPU, the GPU, or the CPU. What is clear from the positioning, and from how similar Strix Halo systems are being used, is that this design is meant to handle local model work without immediately forcing you into a discrete GPU purchase. That also explains why Minisforum leans into “run large models locally” messaging more than it usually does on its mainstream mini PCs.

Cooling and power delivery are tightly linked to the internal hardware decisions. Minisforum rates the system at 130W in Performance mode, 95W in Balanced, and 60W in Quiet, and the cooling stack is built around a copper base, 6 heat pipes, phase change material, and dual turbine fans, with a max fan speed of 3600 RPM. The PSU is internal and rated up to 320W, which helps explain why the chassis is thicker than many of Minisforum’s earlier workstations. In practice, that internal PSU choice also supports the idea that this box is expected to hold higher sustained loads than a typical mini PC without relying on a large external power brick.

There are also a few platform-level details that shape how “workstation-like” it feels. The system supports Windows 11 Pro and Windows 11 24H2 Pro/Home, and the BIOS is positioned as feature-rich, with fan monitoring and tuning options plus platform toggles that matter to power users. This is relevant because the MS-S1 Max is not just built for one narrow purpose, it is built for people who will switch between modes, tweak profiles, and repurpose it across different roles over time. If you treat it like a sealed appliance, you will still get high performance, but you are leaving a lot of what the platform is trying to offer on the table.

Minisforum MS-S1 Max Review – Ports & Connections

The MS-S1 Max is one of the more connectivity-heavy systems Minisforum has put out, and it is clearly designed around the assumption that it will sit in a workstation or lab environment rather than acting as a living-room mini PC. On the front, you get 2 USB4 ports at 40Gbps, a USB 3.2 Gen2 Type-A at 10Gbps, and a 3.5mm TRRS combo jack, plus 2 built-in DMIC mics that are pitched for voice and AI-assisted capture use. In practice, that front layout feels aimed at day-to-day convenience: fast external storage, a dock or capture device, and simple headset or mic options without needing to reach around the back.

On the rear, Minisforum doubles down on bandwidth. There are 2 USB4 v2 ports at 80Gbps, which is the kind of future-proofing that only really makes sense if you plan to use high-speed docks, external storage, or potentially GPU enclosures over time. The review experience lines up with that idea: the ports work as normal USB4 for most peripherals, but the value is really in the headroom, because 80Gbps devices and adapters are still not common in most studios. Alongside those, you get 2 USB 3.2 Gen2 ports at 10Gbps and 2 USB 2.0 ports, which is a more practical mix than it sounds, because it means you are not “wasting” high-speed ports on low-speed peripherals like keyboards, UPS management cables, or dongles.

Networking is a major selling point here, but it is also a slightly divisive one depending on your setup. The MS-S1 Max provides 2 10GbE RJ45 ports, both using Realtek RTL8127 controllers, and it also includes WiFi 7 and Bluetooth 5.4. In use, the wired ports are straightforward and do what you would expect in a compact workstation, including saturating 10GbE when paired with storage that can keep up.

WiFi 7 is also immediately usable, and the practical takeaway is that you can get multi-gig wireless performance without much effort if you already have a WiFi 7 router, but it is still not a replacement for wired 10GbE if you are treating this as part of a storage or production workflow.

Video output is handled through 1 HDMI 2.1 FRL port plus DisplayPort Alt Mode over USB4 and USB4 v2, which makes multi-display setups easy without any additional hardware. Minisforum rates these outputs up to 8K@60Hz and 4K@120Hz, and in the real world that means you can run high-refresh 4K displays or multiple monitors with less compromise than most iGPU-based mini PCs. The only real caveat is that the system leans heavily on USB4 for flexible display and peripheral expansion, so the people who get the most out of the port selection are the ones already planning to use docks, external storage, or high-bandwidth accessories, rather than just plugging in a keyboard and a single monitor.

Minisforum MS-S1 Max Review – Performance & Tests

In day-to-day use, the MS-S1 Max feels less like a typical mini PC and more like a compact workstation that happens to have an iGPU. General desktop operation is consistently responsive, and the platform’s bandwidth-heavy design shows up most clearly when you start stacking tasks that normally push integrated graphics systems into obvious slowdown. One thing that stood out early is how “hot to the touch” the exterior can feel when the system is sitting idle, with thermal imaging showing roughly 55 to 60°C around sections of the chassis and vents in that state. At the same time, internal sensor readings were not presenting anything alarming, which suggests the metal body is doing what it is meant to do as part of heat dissipation, but the idle fan curve behavior did not feel especially reactive until a workload actually kicked in.

Once the system is put under load, the cooling behavior becomes easier to understand and, in practice, more reassuring. During active workloads, the external readings dropped notably in many areas, with measurements around 31 to 34°C being observed on parts of the casing once sustained tasks were running, and internal hot spots that had looked extreme during idle did not remain in that range once the fan profile ramped. Noise levels followed the same pattern: at idle the system sat around 39 to 41 dBA, but under heavier load it ramped to roughly 51 to 53 dBA. It is not silent, but it is also not unexpectedly loud for a high-power APU system with multiple fans and a chassis that is clearly built to move air.

Power draw is one of the more interesting parts of the MS-S1 Max story because it is unusually low when the system is doing very little, then rises quickly once the GPU side is engaged. Idle consumption landed around 13 to 16 W, which is striking given the CPU, GPU, memory bandwidth, and overall positioning of the device. More moderate CPU-oriented workloads pushed consumption into roughly the 45 to 58 W range, with brief spikes into the 70 to 80 W area depending on thread behavior in the test. Once the Radeon 8060S was hit hard in GPU-heavy testing, total system power moved into triple digits, with figures around 141 to 158 W being recorded, which lines up with the idea that this chassis is designed to translate a lot of electrical budget into sustained APU performance rather than short bursts.

Benchmarking results were strong, but the platform’s newness made comparison data less useful than usual in several tools. PCMark produced a score of 8,353, and a run through 3DMark showed a wide spread depending on the test: Solar Bay scored 5,200, Speedway landed at 1,900 with frame rates around 18 to 19 FPS, and Steel Nomad Light cleared 11,000 with an average of 82.3 FPS. Night Raid, which is a better fit for integrated graphics platforms, came in at 70,000 overall, with a graphics score of 130,522 and a CPU score of 19,312. The practical takeaway from these results is that the MS-S1 Max can behave like a “real” gaming-capable APU system in the right workloads, but it also sits in a strange middle ground where some benchmark suites still struggle to place it cleanly against older mini PCs or discrete-GPU desktops.

Minisforum MS-S1 Max Review – Verdict & Conclusion

The MS-S1 Max is easier to understand once you stop thinking of it as a “mini PC with good specs” and instead treat it as a purpose-built Strix Halo workstation in a compact chassis. The big wins are the APU design and the 128GB UMA memory pool, because that combination changes what is practical on integrated graphics, especially for workloads that normally fall over due to VRAM limits. In use, it shows up as a system that can handle serious creative and compute tasks without immediately forcing you into a discrete GPU upgrade path, while still giving you enough connectivity to fit into faster workflows through dual 10GbE, WiFi 7, and USB4 v2. It is not flawless though: the system can feel surprisingly hot to the touch in idle despite internal sensors looking fine, and the fan behavior seems more tuned for “react under load” than “stay cool at rest,” which is a real-world usability detail you notice when it is sitting on a desk near you.

Where things get more complicated is the value discussion. At pricing around the mid/high $2,000 range depending on configuration, this is not competing with mainstream mini PCs at all, and it is not trying to. The audience is much narrower: people who want a high-bandwidth APU platform, who will actually use the memory capacity and fast external connectivity, and who are comfortable paying for that kind of compact engineering. If your workload is mostly general office, light creation, or basic homelab tasks, it is difficult to justify over more conventional systems, including Minisforum’s own smaller workstations. But if you are specifically chasing a compact workstation that can credibly do gaming, content work, and local AI experimentation without a discrete GPU, the MS-S1 Max is one of the few systems that makes that argument feel realistic, even if it comes with the usual early-platform quirks and a price tag that will still put off most buyers.
