GEEKOM A5 Mini PC Review UK 2026

Right, let me be straight with you. I've put together well over two hundred custom builds in the past twelve years, everything from budget office rigs to water-cooled enthusiast monsters. And the honest truth is, for a lot of people, a prebuilt just makes more sense. Not because they're lazy or don't care about their hardware. But because the maths sometimes works out, the convenience is real, and not everyone wants to spend a weekend sourcing parts, waiting on deliveries, and then troubleshooting a POST failure at 11pm. The GEEKOM A5 Mini PC (Ryzen 7 5825U, 16GB, 512GB SSD) Review UK 2026 sits in that interesting space where the question isn't really "is this the fastest thing you can buy" but rather "does it do what it needs to do, at a price that makes sense, without falling apart in six months?"

GEEKOM has been quietly building a reputation in the mini PC space over the last few years. They're not a household name in the same way as some of the bigger prebuilt brands, but they've been consistent enough that I wanted to give the A5 a proper look. This particular configuration pairs AMD's Ryzen 7 5825U with 16GB of RAM and a 512GB SSD, all crammed into a chassis you could genuinely fit in a bag. I ran it through three weeks of real-world use, covering productivity workloads, light creative tasks, and yes, some gaming. Here's what I found.

The budget tier for mini PCs is a crowded and often disappointing place. Lots of machines promise the world and deliver something that throttles the moment you push it. So the question going in was simple: does the GEEKOM A5 hold up under sustained load, or does it join the long list of compact PCs that look great on a spec sheet and then thermal-throttle their way into mediocrity?

Memory comes in at 16GB of DDR4, running in dual channel. The 512GB SSD is an NVMe unit, which is good to see at this price point. Some budget mini PCs still ship with SATA SSDs and try to hide it in the small print. Storage connectivity matters more than people realise in day-to-day use, so it's a positive that GEEKOM hasn't cut that particular corner here. The machine ships with Windows 11 Pro, which is another small but meaningful detail. Home is fine for most people, but Pro gives you more flexibility, especially if you're using this in a business or hybrid work context.

Display output is handled by the integrated Radeon graphics built into the 5825U. You get up to four display outputs depending on the port configuration, which is actually one of the more compelling use cases for a machine like this. Multi-monitor productivity setups are where mini PCs genuinely shine. The unit itself is compact, fanless-looking from the outside but definitely not fanless internally, and comes with a VESA mount bracket so you can stick it behind a monitor. That's a nice touch.

Where things get more nuanced is sustained performance. Because this is a mobile chip in a small chassis, thermal headroom is limited. In our testing, running Cinebench R23 multi-core repeatedly, the chip starts strong and then settles into a slightly lower sustained performance level as thermals build up. It doesn't throttle dramatically, which is credit to GEEKOM's thermal design, but you will see some drop-off compared to the initial burst. For most productivity tasks this genuinely doesn't matter. You're not running Cinebench loops in real life. But if you're doing sustained video encoding or compiling large codebases for hours at a time, you'll notice it.

For the target use case, though, this is a capable machine. In our testing it handled 1080p video editing in DaVinci Resolve for lighter projects without too much complaint. Microsoft Office, web browsing with thirty-plus tabs, Zoom calls with screen sharing, all fine. The 5825U also has a reasonably capable integrated GPU (more on that in the next section), which helps with some accelerated tasks. Compared to older Intel-based mini PCs at similar prices, the AMD chip holds up well, particularly in multi-threaded workloads where Zen 3's architecture gives it a real advantage.

What the integrated Radeon can handle is older and less demanding titles. In our testing, games like Rocket League, CS2 at low settings, Minecraft, and older indie titles ran at playable framerates at 1080p. We're talking 30 to 60fps depending on the game and settings, which is fine for casual play. Anything more demanding, your modern open-world games, anything with ray tracing, anything at 1440p or above, forget it. The integrated GPU simply doesn't have the horsepower. It shares system memory rather than having dedicated VRAM, which is another limiting factor.

Where the graphics do shine is in productivity-adjacent tasks. Multi-monitor setups work well, hardware-accelerated video playback is smooth, and light creative work benefits from the GPU acceleration. If you're a casual gamer who plays older titles or less demanding games, the A5 can handle that. But this machine is not positioned as a gaming PC, and anyone buying it expecting gaming performance comparable to even a budget discrete GPU is going to be let down. Be honest with yourself about what you actually play before buying.

The SO-DIMM slots are accessible if you want to upgrade. The A5 supports up to 64GB of DDR4 across two slots, so there's genuine headroom there. Starting with 16GB is sensible for most users, but if you're planning to use this for more memory-intensive work, knowing you can expand is reassuring. In our testing, 16GB was sufficient for typical productivity workloads with no paging issues, though heavy multitasking with memory-hungry applications did push usage into the 12-14GB range fairly regularly.

Storage is a 512GB NVMe SSD, and in our testing it performed well. Sequential read speeds were in the region of what you'd expect from a decent mid-range NVMe drive, making boot times and application loading feel quick. There's also a second M.2 slot available, which is a big deal. You can add a second SSD without replacing the existing one, which means expanding storage is straightforward and non-destructive. There's also a 2.5-inch SATA bay on some configurations, though you'll want to verify this for the specific unit you're buying. Either way, storage expandability is better than average for a mini PC at this size and price.

In our three weeks of testing, the A5 managed thermals better than I expected. Under sustained CPU load, temperatures settled in the mid-to-high 80s Celsius, which is warm but within acceptable limits for a mobile chip in this form factor. The fan does spin up audibly under load, and in a quiet room you'll hear it. It's not loud, more of a consistent hum than a jet engine, but it's there. At idle and during light tasks, it's essentially silent, which is good for an office or living room environment.

One thing worth noting is that the A5 does benefit from having some airflow around it. Don't stuff it in a tight cabinet with no ventilation. GEEKOM includes a VESA mount bracket, and mounting it behind a monitor is actually the ideal scenario thermally, as it gets ambient airflow and doesn't sit on a desk surface trapping heat underneath. We tested it in both configurations and the mounted setup ran a few degrees cooler under sustained load. Small difference, but worth knowing.

Internally, there's not a lot of cable management to speak of because there aren't many cables. The power delivery comes in via the external brick, the storage and RAM are on the board, and the fan connects directly. It's a clean internal layout by necessity rather than design, but the result is a tidy interior that's easy to work in when you need to upgrade RAM or storage. The M.2 slots are accessible without too much fiddling, which I appreciate.

The external power brick is worth mentioning because it's a point of contention with mini PCs generally. You're trading an internal PSU for an external adapter, which keeps the chassis small but means another brick on your desk or behind your monitor. The 90W adapter is adequate for the chip's power envelope with headroom to spare, and it's a standard barrel connector rather than anything proprietary, which is good for long-term repairability. Overall, the build quality is appropriate for the price tier. It doesn't feel premium, but it doesn't feel cheap either. Proper mid-range construction.

The 2.5GbE ethernet is a highlight. Most budget mini PCs ship with standard gigabit ethernet, so having 2.5GbE here is a meaningful upgrade for anyone on a faster home network or using this in a NAS-adjacent role. Wi-Fi 6 (802.11ax) is also included, which is current-generation wireless and noticeably better than the Wi-Fi 5 you'll find in older or cheaper units. Bluetooth 5.2 rounds out the wireless connectivity. There's also a 3.5mm audio jack for headphones or speakers.

The multi-monitor capability deserves a specific mention because it's one of the strongest arguments for this machine in a productivity context. Being able to drive three monitors from a unit the size of a paperback book is genuinely useful. In our testing we ran a dual-monitor setup without any issues, and the display outputs handled 4K at 60Hz without complaint. If you're setting up a compact home office or a secondary workstation, the connectivity here covers most bases without needing a dock or hub.

Bloatware is minimal, which I was pleased to find. There's a GEEKOM utility app pre-installed for things like fan control and system monitoring, which is actually useful rather than just marketing software. Beyond that, the install is fairly clean. No trials of antivirus software, no browser toolbars, no third-party junk that you have to spend twenty minutes uninstalling before the machine feels like yours. That's not always the case with budget prebuilts, so credit where it's due.

The GEEKOM utility itself is worth a look. It gives you some control over performance profiles, letting you choose between a quieter, more thermally conservative mode and a higher-performance mode that lets the chip run harder. In our testing, the performance mode made a noticeable difference in sustained workloads, at the cost of more fan noise and higher temperatures. For most users the balanced default is probably the right call, but having the option is good. Driver support has been fine throughout our testing period, with Windows Update handling most of what's needed without manual intervention.

Storage expansion is similarly accessible. The primary M.2 slot holds the included 512GB NVMe SSD, and there's a second M.2 slot available for adding more storage without replacing anything. This is a big deal for a machine at this size and price. You can add a second NVMe drive, or depending on the slot type, a SATA M.2 drive. Check the specifications for the exact slot configuration before buying a specific drive, but the expandability is there. Some configurations also include a 2.5-inch SATA bay, which gives you another option for adding a larger spinning disk or SATA SSD if you need bulk storage.

Where upgrade potential hits a hard wall is the CPU and GPU. The Ryzen 7 5825U is soldered to the board. You cannot swap it out. And there's no discrete GPU slot, no PCIe expansion, nothing of that sort. This is the fundamental trade-off of the mini PC form factor. What you get is what you get in terms of processing and graphics power. The machine is also powered by an external brick rather than a standard ATX PSU, so there's no upgrading the power delivery either. If you outgrow the CPU performance in a few years, you're looking at replacing the whole unit rather than just the processor. That's worth factoring into your buying decision.

The Beelink SER5 Max uses the 5800H rather than the 5825U. The 5825U is essentially a business-focused variant with slightly different power management and a longer support lifecycle, but in raw performance terms they're very close. The Beelink tends to be slightly more aggressive on pricing and has a strong community following, but GEEKOM's build quality and software support have historically been a bit more polished. The Intel NUC 13 Pro brings Alder Lake architecture and Iris Xe graphics, which in some GPU-accelerated tasks can edge ahead of the Radeon integrated graphics in the AMD chips. But the NUC 13 Pro typically commands a premium that's hard to justify for most users.

The Ryzen 7 5825U is a capable chip for productivity work, the dual-channel 16GB RAM configuration is the right call, the NVMe storage is quick, and the port selection is genuinely good for the size. Windows 11 Pro out of the box is a nice touch. Thermal management is adequate without being exceptional, and the upgrade path for RAM and storage gives you some flexibility down the line. For a compact productivity machine, a home office PC, a media centre, or a secondary workstation, this is a solid option at a competitive price.

The limitations are real though, and worth being clear about. No discrete GPU means gaming is limited to older and less demanding titles. The CPU is soldered, so you're locked into the 5825U for the life of the machine. And while the thermals are managed well enough, sustained heavy workloads will see some performance drop-off compared to a desktop chip with proper cooling. If you need serious gaming performance or sustained heavy compute workloads, a traditional desktop build will serve you better. But if you need a capable, compact, quiet machine for everyday work and the occasional casual game, the GEEKOM A5 makes a strong case for itself.

Our editorial score for the GEEKOM A5 is 7.5 out of 10. It's not perfect, but it's genuinely good at what it's designed to do, and at a budget price point, that's more than enough to recommend it to the right buyer.
