GEEKOM A5 Mini PC UK Review 2026: Is This Compact Powerhouse Worth Your Money?

The GEEKOM A5 Mini PC UK has landed on my desk, and I’ll be honest – I wasn’t expecting much from a sub-£400 mini PC. After spending two weeks testing this compact system powered by AMD’s Ryzen 5 7430U, I’ve come away genuinely impressed by what GEEKOM has managed to pack into this tiny chassis. But is it actually worth buying, or should you build your own system instead?

What’s Inside the GEEKOM A5 Mini PC UK

Right, let’s crack this thing open and see what GEEKOM has actually put inside. Unlike some manufacturers who hide proprietary nonsense, I was pleasantly surprised to find mostly standard components that you could theoretically source yourself.

The Ryzen 5 7430U is actually a solid choice for this form factor. It’s a 15W TDP chip that can boost to 25W, giving you proper 6-core performance without turning your desk into a hotplate. The Vega 7 integrated graphics won’t win any gaming awards, but it handles 8K video decode through USB4 and can drive four displays simultaneously, which is genuinely impressive.

What I appreciate most is the use of standard SODIMM RAM rather than soldered memory. Too many mini PCs lock you into whatever configuration you buy, but GEEKOM has given you two slots with proper upgrade potential. The storage situation is equally sensible with an M.2 2280 slot plus space for an additional 2.5-inch drive.

The motherboard is custom, which is expected at this size, but it’s well-designed with decent component spacing and proper thermal management. If you’re interested in other compact desktop options, check out our Mac Mini M4 review for comparison with Apple’s approach to mini PC design.

Performance Tests: Real-World Numbers

Benchmark time. I’ve put the GEEKOM A5 Mini PC UK through its paces with both synthetic tests and real-world workloads to see how it actually performs when you’re using it day-to-day.

CPU Performance: In Cinebench R23, the Ryzen 5 7430U delivered 8,342 points multi-core and 1,487 points single-core. That’s roughly equivalent to an Intel i5-1135G7, which means you’ve got enough grunt for productivity work, light photo editing, and multiple Chrome tabs without breaking a sweat. Geekbench 6 scores came in at 1,654 single-core and 6,892 multi-core.

Graphics Performance: The Radeon Vega 7 managed 1,547 points in 3DMark Time Spy, which puts it firmly in the “casual gaming only” category. You can play older titles like CS:GO at 1080p medium settings (averaging 65fps), but don’t expect to run anything demanding. This isn’t a gaming machine – it’s a productivity workhorse.

Storage Speed: The included 512GB NVMe drive posted sequential reads of 3,421 MB/s and writes of 2,987 MB/s in CrystalDiskMark. Not the fastest Gen3 drive I’ve tested, but perfectly adequate for boot times and application loading. Windows 11 Pro boots in about 8 seconds from power button to desktop.

Real-World Usage: I spent a week using this as my primary work machine, and it handled everything I threw at it. Video calls on Teams whilst editing documents, 20+ browser tabs, Spotify streaming, and occasional Lightroom work all ran smoothly. The 16GB of RAM is the sweet spot for this use case – 8GB would struggle, 32GB would be overkill for most users.

Where it falls down is video editing. Rendering a 5-minute 4K timeline in DaVinci Resolve took 18 minutes, which is painfully slow compared to systems with discrete GPUs. If you’re doing serious content creation, you’ll want something more powerful like the systems in our CyberPowerPC Luxe Gaming PC review.

Thermals & Noise: Surprisingly Well Sorted

This is where many mini PCs fall flat on their faces. Cramming components into a tiny chassis usually means thermal throttling and jet engine fan noise. GEEKOM has actually done a decent job here.

During a 30-minute Cinebench loop, CPU temperatures stabilised at 76°C with the fan spinning at around 2,400 RPM. That’s perfectly safe for a mobile chip in this form factor, and there was no thermal throttling. The cooling system uses a dual-heatpipe design with a small but effective blower fan.

Noise levels are genuinely impressive. At idle, you can’t hear the system at all from a normal desk distance – it measured 28 dBA, which is essentially ambient room noise. Under full load, it reaches 34 dBA, which is about as loud as a quiet conversation. I’ve tested mini PCs that sound like hairdryers under load, so this is a pleasant surprise.

The chassis stays cool to the touch during normal use, with only the top vent area getting noticeably warm under sustained load. The aluminium construction helps with heat dissipation, and the ventilation design is well thought out with intake on the bottom and exhaust out the top.

One minor grumble: the fan curve is a bit aggressive when you first wake the system from sleep, ramping up to full speed for about 5 seconds before settling down. It’s not a dealbreaker, but it can be startling in a quiet room.

Upgrade Potential: Better Than Expected

This is where the GEEKOM A5 Mini PC UK separates itself from cheaper competitors. You can actually upgrade this thing without voiding your warranty or needing specialist tools.

I opened up the system to check the upgrade process, and it’s genuinely straightforward. Four Phillips screws on the bottom panel, then you’ve got full access to both RAM slots and the storage bays. No proprietary connectors or weird mounting systems – just standard components you can buy anywhere.

The 2.5-inch drive bay includes a mounting bracket and SATA cable already installed, which is a nice touch. You can chuck in a cheap 2TB SATA SSD for about £80 if you need more storage for media files or game libraries (though again, this isn’t a gaming machine).

For comparison, if you’re looking at other compact systems, our GEEKOM A5 with Ryzen 7 5825U review covers the higher-spec variant with slightly better CPU performance.

Build vs Buy Analysis: Is DIY Worth It?

Here’s the big question: could you build something equivalent for less money? Let’s crunch the numbers properly.

The maths gets even more favourable when you consider that building a mini-ITX system is significantly more fiddly than a standard ATX build. Cable management in tiny cases is a nightmare, and you need to be careful about component compatibility. Plus, the Ryzen 5 7430U in the GEEKOM is a mobile chip – you can’t actually buy it retail, so any DIY build would use a desktop APU like the 5600G, which has different power characteristics.

The Windows 11 Pro licence is a massive part of the value equation. If you genuinely need Pro features (BitLocker, Remote Desktop, domain joining for business use), that’s £180 saved right there. If you only need Home edition, you could knock £80 off the DIY price, but you’re still not saving enough to justify the hassle.

Where DIY makes more sense is if you need more performance or want discrete graphics. Check our Vibox II Gaming PC review for an example of a budget gaming build where the value equation is different.

Warranty & Support: Actually Impressive

GEEKOM is making a big deal about their warranty coverage, and for once, the marketing isn’t just hot air.

The 3-year (1,095-day, as they oddly specify) warranty is double what most competitors offer. I contacted GEEKOM support with a technical question during testing, and got a detailed response within 18 hours, which is respectable. They operate primarily through email support rather than phone, which some people won’t like, but the quality of responses was good.

According to their warranty documentation, they cover manufacturing defects and hardware failures, with advance replacement available in some regions. UK buyers get standard warranty service, though you’ll need to cover return shipping costs if something goes wrong. That’s fairly standard for this price point.

The fact that user upgrades don’t void the warranty is a major plus. Too many manufacturers use warranty threats to lock you into their ecosystem, so GEEKOM deserves credit for being consumer-friendly here.

One caveat: GEEKOM is a smaller brand compared to Dell or HP, so long-term support and parts availability are less certain. If you need enterprise-level support with guaranteed response times, you’ll want to look at business-class systems instead.
