GEEKOM A5 Mini PC UK Specs Overview

The heart of this system is AMD’s Ryzen 7 5825U, a mobile processor that’s found its way into this compact desktop form factor. Let’s examine what you’re actually getting under the hood.

The Ryzen 7 5825U is built on AMD’s Zen 3 architecture at 7nm, which explains its impressive efficiency. That 15W TDP is configurable up to 25W, and GEEKOM has tuned this system to balance performance with thermal management. The 16GB of DDR4-3200 memory (not LPDDR, thankfully) is expandable to 64GB, whilst the 512GB NVMe SSD can be supplemented with additional M.2 SATA and 2.5-inch drives.

What immediately struck me about the GEEKOM A5 Mini PC UK configuration is that it’s a complete system. You’re not buying a barebones kit – Windows 11 Pro is pre-installed, the RAM is already fitted, and storage is ready to go. For anyone who remembers the days of Intel NUCs requiring separate purchases of everything except the motherboard, this is refreshingly straightforward.

Gaming Performance: Setting Realistic Expectations

Let’s address the elephant in the room – this isn’t a gaming PC, and GEEKOM doesn’t pretend it is. The Radeon Vega 8 integrated graphics are based on older RDNA architecture, and whilst they’re competent for display output and light gaming, you’re not running Cyberpunk 2077 at 1080p here.

Productivity Performance: Where This Mini PC Excels

The GEEKOM A5 Mini PC UK genuinely impressed me in productivity workloads. Rendering a 10-minute 1080p video in DaVinci Resolve took 8 minutes 45 seconds, which is respectable for a 15W processor. Blender’s BMW benchmark completed in 12 minutes 20 seconds on CPU rendering. These aren’t desktop Ryzen 9 numbers, but they’re perfectly adequate for freelancers and small businesses.

What sets this system apart is its display connectivity. Dual HDMI 2.0 ports and dual USB4 Type-C outputs enable quad 4K displays simultaneously. I tested with three 1440p monitors, and the system handled Excel spreadsheets, Chrome with 30+ tabs, and Slack without breaking a sweat. The USB4 ports support 8K output via DisplayPort Alt Mode, though finding an 8K monitor at a reasonable price remains challenging in 2026.

For comparison, the Mac mini M4 Pro offers superior single-threaded performance and better GPU capabilities, but costs significantly more. If you’re embedded in the Windows ecosystem and need multi-display support without spending £800+, the GEEKOM A5 Mini PC UK represents compelling value.

Power Consumption and Thermal Management

One of the most pleasant surprises with the GEEKOM A5 Mini PC UK was its power efficiency. This matters more than you might think – over a year of typical office use, the difference between a 15W and 65W system adds up to genuine savings on your electricity bill.

At idle, the system sips just 8W from the wall. Running a Cinebench R23 multi-core loop, power consumption peaked at 45W total system draw. Even during extended video rendering sessions, I never saw the power brick exceed lukewarm temperatures. For context, a typical desktop Ryzen 7 5700X system would draw 120-150W under similar workloads.

GEEKOM has engineered the cooling system thoughtfully. Two small fans exhaust heat efficiently, and whilst they’re audible during intensive tasks, they’re quieter than most desktop tower systems. During typical office work, the fans remain nearly silent. After 30 minutes of Cinebench looping, CPU temperatures stabilised at 78°C, well below the 95°C thermal limit.

Platform Costs: Complete System Value

Here’s where the GEEKOM A5 Mini PC UK truly distinguishes itself from traditional desktop builds. You’re not just buying a processor – you’re getting a complete, functioning system with everything included.

The value proposition becomes crystal clear when you factor in Windows 11 Pro. Microsoft charges £139.99 for a retail licence, which alone represents a significant portion of the GEEKOM A5 Mini PC UK price. Add the compact form factor, pre-configured BIOS settings, and three-year warranty, and suddenly building an equivalent system yourself makes little financial sense.

There’s no upgrade path in the traditional sense – the processor is soldered, and you can’t swap in a new motherboard. But you can expand RAM to 64GB and add up to 5TB of total storage using the additional M.2 and 2.5-inch bays. For most users, this flexibility suffices.

Alternatives to the GEEKOM A5 Mini PC UK

The mini PC market has become increasingly competitive, with options ranging from budget Intel systems to Apple’s M-series silicon. Here’s how the GEEKOM A5 Mini PC UK stacks up against key alternatives.

The Mac mini M4 offers superior performance, particularly in single-threaded tasks and GPU-accelerated workloads. However, it costs £225 more and locks you into macOS. If you’re already invested in Apple’s ecosystem, it’s worth the premium. For Windows users, the GEEKOM A5 Mini PC UK provides better value.

Intel’s NUC 12 Pro features a newer 12th-gen processor with hybrid architecture, delivering better single-threaded performance. However, Intel’s pricing strategy means you’re buying a barebones kit – add RAM, storage, and Windows, and you’re approaching £650. The GEEKOM A5 Mini PC UK includes everything for significantly less.

Beelink’s SER5 Max uses the more powerful Ryzen 7 5800H (45W TDP vs 15W), offering approximately 20% better multi-threaded performance. It costs £45 more but lacks Windows 11 Pro (typically ships with Home edition). If you need maximum CPU performance and don’t value the Pro features, it’s worth considering.

For users seeking discrete graphics, the Vibox VIII Gaming PC offers genuine gaming capabilities, though at a significantly higher price point and much larger form factor.

Connectivity and Expansion Options

The GEEKOM A5 Mini PC UK doesn’t skimp on connectivity. The front panel features two USB 3.2 Gen 2 Type-A ports and a 3.5mm audio jack for convenient access. Round the back, you’ll find dual HDMI 2.0 ports, dual USB4 Type-C (40Gbps, DisplayPort Alt Mode, Power Delivery), two additional USB 3.2 Gen 2 Type-A ports, and Gigabit Ethernet.

Wi-Fi 6 (802.11ax) and Bluetooth 5.2 are integrated, and in testing, wireless performance proved reliable. I consistently achieved 450Mbps+ on my 500Mbps fibre connection, which is more than adequate for video conferencing and cloud storage synchronisation. The Wi-Fi 6 implementation is noticeably faster than older Wi-Fi 5 systems, particularly in congested environments.

Internally, the expansion options are practical rather than extensive. The 16GB DDR4-3200 SO-DIMM modules can be replaced with 32GB sticks for 64GB total. An additional M.2 2280 SATA slot accommodates a second SSD, and there’s a 2.5-inch bay for traditional SATA drives. This flexibility means you can start with the base 512GB and expand as your storage needs grow.

One limitation worth noting: the USB4 ports don’t support external GPU enclosures effectively. I tested with a Razer Core X eGPU, and whilst it technically functioned, performance was severely constrained by the mobile processor and BIOS limitations. If you’re hoping to add discrete graphics later, this isn’t the platform for it.

Real-World Use Cases

After several weeks with the GEEKOM A5 Mini PC UK, I’ve identified the scenarios where it genuinely excels. For home office workers running Microsoft Office, web browsers, and video conferencing software, this system is frankly overkill in the best possible way. Teams calls remain smooth even with screen sharing and multiple participants, and the quad-display support transforms productivity for financial analysts or developers who live in spreadsheets and IDEs.

Content creators working with 1080p video will find the performance adequate, though 4K editing pushes the limits. I edited a 12-minute YouTube video in Premiere Pro with colour grading and transitions, and whilst timeline scrubbing wasn’t buttery smooth, exports completed in reasonable timeframes. For professional work, you’d want more GPU horsepower, but for hobbyists and side projects, it’s serviceable.

As a development machine, the GEEKOM A5 Mini PC UK handles Docker containers, Node.js builds, and Visual Studio Code without complaint. Compiling a medium-sized React project took 38 seconds, which isn’t blazingly fast but doesn’t disrupt workflow. The 16GB of RAM proved sufficient for my typical workload, though I’d recommend upgrading to 32GB if you’re running virtual machines or large datasets.

For digital signage, kiosk applications, or always-on server tasks, the low power consumption and compact size make this an ideal candidate. At 8W idle, you could run this 24/7 for approximately £15 per year in electricity costs (based on UK average of 28p per kWh). Compare that to a traditional desktop drawing 50W idle, and the savings accumulate quickly.

Build Quality and Design

GEEKOM has constructed the A5 from metal rather than plastic, which lends it a premium feel that belies the modest price. The chassis measures 117 x 112 x 37mm, making it genuinely portable – I carried it to a client meeting in my laptop bag without issue. At 640g, it weighs less than most hardback books.

The industrial design is understated, with a matte black finish that doesn’t attract fingerprints. There’s a subtle GEEKOM logo on the top panel, but otherwise, it’s refreshingly anonymous. The power button sits on the front alongside the USB ports, and it’s satisfyingly clicky rather than mushy.

Internally, the layout is dense but logical. Accessing the RAM and storage requires removing four screws on the bottom panel, after which the components are readily accessible. GEEKOM includes a small screwdriver in the box, which is a thoughtful touch. The cooling solution uses copper heat pipes and dual fans, and the thermal paste application appeared even and adequate when I inspected it.

One minor niggle: the power brick is relatively large for a 65W adapter. It’s not enormous, but it’s noticeably bulkier than modern GaN chargers. This is a cost-saving measure rather than a functional limitation, and it doesn’t meaningfully impact the overall package.
