Beelink SER8 Mini PC

You get a surprisingly capable tiny desktop with the Beelink SER8 (2025 Edition). It pairs an AMD Ryzen 7 8745HS with integrated Radeon 780M graphics, 32GB of DDR5 and a 1TB PCIe 4.0 NVMe drive, so everyday browsing, streaming and light creative work feel snappy. The SER8’s strength is how it balances performance and a small footprint — you can tuck it behind a monitor, run three 4K displays (HDMI 2.1 + DP1.4 + USB4) and still keep a clean desk.

The updated metal case and steam-chamber cooling help keep noise down, though sustained heavy loads will warm things up faster than a full tower. If you’re deciding between compact options, the Beelink SER8 (2025 Edition) leans toward those who want a near-desktop experience without the bulk — contrast that with a value-focused competitor like the ACEMAGIC S5 (2025 Edition) and you’ll notice the SER8 favors higher single-core speed and better integrated graphics.

Practical uses range from a solid home office box and media center to a SteamOS living-room machine or a compact photo-editing station. If you want a small, versatile desktop that mostly stays out of the way while letting you get work or play done, this is a very usable choice.

What People Say

Users like that the SER8 feels faster than expected for its size, is easy to set up, and stays quiet for day-to-day use. People often praise the accessible internals (easy RAM/SSD swaps) and how well it runs SteamOS or as a media box.

Common caveats: Wi‑Fi range can be weak at a distance and a few buyers reported support or reliability hiccups over time.

Overall Sentiment: Positive

🗣️ ScorpioWolf

Setup was quick, and the unit felt fast and quiet. I swapped in RAM and an SSD from another machine without trouble — the case is easy to open and the ports/map are sensible. Drivers were easier to get from AMD than Beelink’s site, and daily use felt on par with pricier NUC systems.

🗣️ TJW

Perfect for installing SteamOS: I wiped Windows, installed SteamOS, paired a controller, and it ran smoothly as a living-room machine. Wifi and Bluetooth worked fine, and it stayed quiet and cool for the lighter games and media I tested.

Innovation Highlights

Packing a Zen 4 mobile chip (Ryzen 7 8745HS) with a 12‑core Radeon 780M GPU into a palm-sized chassis is the main innovation here. Add PCIe 4.0 storage, DDR5 memory at 5600MHz, USB4 video output and a redesigned metal case with a steam-chamber cooling solution, and you get a mini PC that aims to replace a traditional desktop for many daily tasks while keeping a very small footprint.

What People Say

Most people highlight fast real‑world performance (gaming and productivity), easy setup and good Linux support. Reviewers mention solid thermal behavior and quiet operation under normal loads.

On the flip side, a minority reported reliability or stability issues (BSODs, Wi‑Fi/antenna quirks or units that failed after months), so you may want to keep an eye on firmware updates and support threads.

Overall Sentiment: Positive

🗣️ Larry C.

All the above and more. I was skeptical buying the mini-PC, especially after hours of reviews. This one nailed everything I needed and more for my kid. He needed a gaming PC for R6 Siege, random you tubing etc. Out the box it clearly outperformed his old gaming PC that wouldn't update to windows 11. Lightning fast set up, download, and play. 120FPS in R6 without even hitting the system max. He was happier than I've seen him while loading up and playing. Will buy again for my other kids. Great value for all you get. Gaming quality and capabilities unmatched for price. Thank you Mini forum.

🗣️ Slo_matt

TLDR: The Minisforum UM790 Pro is a great little device with excellent Linux compatibility and surprisingly strong gaming chops for its price point. Recommended. I purchased the 64GB version of the UM790 Pro, and I've had it for about two weeks. I've been happy with it so far. I run Kubuntu Linux on mine and I have not had any problems. Installation was a breeze with no unusual steps required. All ports seem to be working out of the box. I primarily use my UM790 Pro for web development and general productivity, and it excels at both. I've tried a few games just to see how this little device handles them. It's pretty impressive for the price point. ... The UM790 Pro offers a lot of value for the dollar, and I'd recommend it to anyone in the market for a good Mini PC.

Innovation Highlights

What stands out is packing a mobile Zen4 Ryzen 9 into a palm-sized chassis with features you usually see in larger desktops: liquid metal Cold Wave cooling, two PCIe 4.0 M.2 slots, and two full‑speed USB4 ports with PD support. That mix of high-end connectivity and compact cooling lets the UM790 Pro behave like a scaled‑down desktop rather than a basic mini box.

Key Benefits

• Desktop-class Ryzen 9 7940HS and Radeon 780M deliver strong multi-thread and integrated‑GPU performance
• DDR5 memory and dual PCIe 4.0 M.2 slots for fast, upgradeable storage and smooth multitasking

Beelink SER5 MAX

You get a compact but capable mini PC with the Beelink SER5 MAX — it feels like a proper desktop squeezed into a palm-sized box. The Ryzen 7 6800H and 32 GB of LPDDR5 make everyday tasks snappy, and the dual PCIe 4.0 slot plus 1 TB SSD give you room to grow.

Practically, you can use it as a tidy home‑office workstation, a quiet living‑room media hub for 4K content, a light gaming machine for titles like LoL and CSGO, or a small DAW/editing box. A few reviewers set it up as a home theater PC or fleet machines for offices and report solid reliability, though you may notice it’s sometimes louder than similarly specced Dell micros.

If you’re comparing small form factors, it sits between beefier bricks like the Beelink SER8 (2025 Edition) and slimmer options such as the Geekom A6 Mini (2025 Edition): more ports and expansion than the smallest models, less thermal headroom than the largest enthusiast boxes. If you want a versatile little PC that behaves like a full desktop without taking much desk space, this is an easy one to recommend.

What People Say

Users praise the SER5 MAX for reliable real‑world performance in office, media and light‑gaming roles, plus easy expandability. Common caveats are slightly louder fans compared with some micro PCs and occasional minor fit-and-finish issues (USB port quirks, missing monitor screws).

Overall Sentiment: Positive

🗣️ Ochadd

Solid little machines. I’ve bought over 200 Beelink SER models for small businesses; two fans needed replacing, and Beelink sent parts free. None have totally failed — great ROI for office use, though a bit louder than comparable Dell micros.

🗣️ D. Short

Works well so far. Came with Windows 11 Pro; I did need an AMD video driver update. The extra slot for a 2.5" SSD is really convenient, but be careful with the small ribbon cables if you open the case, and note the VESA screws weren’t the correct size for my monitor.

Innovation Highlights

The SER5 MAX stands out by packing a high‑clock mobile Ryzen into a tiny chassis while keeping sensible expandability — dual M.2 PCIe 4.0, a 2.5" bay and triple‑4K output. That combination makes it more of a do‑it‑all mini desktop compared with ultra‑compact rivals; it borrows the best parts of larger mini workstations but in a much smaller footprint.

Key Benefits

• Desktop‑class Ryzen 7 6800H plus 32 GB LPDDR5 delivers responsive multitasking and light creative work
• 1 TB PCIe 4.0 M.2 SSD with dual slot expandability (and a 2.5" bay) for easy storage upgrades
• HDMI + DisplayPort + USB‑C triple‑display support for 4K workflows and multitasking
• Plenty of I/O: 2.5G LAN, USB3.2 and USB2.0 ports, Wi‑Fi 6 and Bluetooth 5.4 for modern connectivity
• Compact, VESA‑mountable design that tucks behind a monitor or fits small desks without losing ports
• Beelink technical support and useful features like auto power‑on make deployment easier

FAQ

Which Mini PC Should You Choose For Your SFF Desktop Needs?

You should base your choice on the tasks you plan to run and the physical constraints of an SFF desktop. If you want a balanced, well‑rounded option with strong everyday and light creative performance plus convenient rear USB4/USB‑C ports, consider the Geekom A6 Mini (2025 Edition).

If you need triple‑display support and solid integrated graphics for media or light gaming, the Beelink SER8 (2025 Edition) is a good fit. If top raw CPU/GPU headroom, Linux compatibility and eGPU potential matter most, the Minisforum UM790 Pro (2025 Refresh) is aimed at power users; check that the USB4/Thunderbolt‑class ports and firmware support the external GPU you plan to use.

Include the ACEMAGIC S5 (2025 Edition) in your shortlist if you prioritise extreme compactness or a unique port layout, but verify thermal design and port placement first. Always prioritise ports and thermals, ensure the model supports the RAM and storage upgrades you may need, and confirm vendor driver/firmware support before you commit.

Can These Mini PCs Handle Gaming, Video Editing, And Multi‑Monitor Workflows?

You can run esports titles, 1080p creative workflows, and multi‑monitor productivity on these mini PCs, but expectations should match the hardware. Integrated GPUs like Radeon 680M and 780M are excellent for streaming, video editing timelines, and competitive games at medium settings, while the UM790 Pro’s Ryzen 9 class silicon gives you more headroom for heavier editing and higher framerates. For serious 3D AAA gaming or GPU‑accelerated renders, plan for an external GPU solution where supported; verify that the USB4/40Gbps ports on a given model and its firmware allow eGPU passthrough.

To get the best results, set your power/thermal profile in BIOS or vendor software, prefer fast NVMe storage for scratch disks, and use multiple display outputs on the rear to avoid cable clutter and signal issues.

What Practical Steps Should You Take During Setup And When Upgrading A Mini PC?

When you unbox a mini PC, start by updating the BIOS and chipset/graphics drivers from the vendor or AMD site to avoid known stability issues, and register the device for warranty. Check physical port placement and VESA mounting screws before final installation so you don’t have to remount later, and pay attention to Wi‑Fi antenna orientation—some units have poor wireless range if the antenna is blocked. If you plan upgrades, confirm the number and type of SODIMM and M.2 slots; many small units limit internal expansion so use a NAS or external SSD for large media projects. Finally, monitor temperatures under load for the first few hours, tweak fan or performance curves if firmware allows, and keep backups of your system image before performing major changes.

Customer Preferences

When choosing between the GEEKOM A6, Beelink SER8, and MINISFORUM UM790 Pro, you typically prioritize raw CPU/GPU performance, memory and storage expandability, and thermal design because those factors determine whether the mini PC can handle gaming, content creation, or heavy multitasking. You also weigh I/O connectivity, wireless options, noise and power efficiency, and overall price-to-performance to match your intended use—leaning toward the higher-performance SER8 or UM790 Pro for demanding work and the GEEKOM A6 for a more compact, budget-friendly setup.
