If you’re into self-hosting and looking for an efficient mini PC, the Geekom A5 2025 edition is worth your attention. This compact system boasts low power consumption while delivering impressive performance for server workloads in your home lab. Let’s explore its features, specifications, and why it’s an ideal choice for hosting your VMs seamlessly.
First Impressions and Build Quality
The Geekom A5’s design stands out with its robust build quality, reminiscent of previous Geekom devices. The case feels sturdy—often resembling metal—unlike cheaper alternatives with plastic housings. A notable design feature is the accessible screws on the bottom feet, securely attached to the housing, enhancing ease of maintenance. While I appreciate some tool-less designs, the A5 strikes a good balance between accessibility and quality.

Unboxing the Geekom A5
The A5 arrives well-packaged, signaling its high-quality construction. Upon unboxing, the top view reveals its compact form and I/O ports, including USB connectors and a headphone jack. A detailed look inside shows the internal components, including a SATA bay for additional storage.
Proxmox Compatibility and Performance
I successfully installed Proxmox VE 8.4 using a Ventoy USB drive, with no need for additional drivers. Despite its mobile CPU, the Ryzen 5 excels at handling virtual machines. I was able to run instances of Ubuntu Server, Pi-hole, and Portainer without any CPU spikes, showcasing its capability for light to moderate container workloads.
Power Consumption
The most impressive aspect of the A5 is its power efficiency. During idle, it consumes just 4 watts—an astonishing achievement in the mini PC category! Under stress tests, the maximum power draw only reaches 25 watts. This efficiency is particularly appealing for users focusing on self-hosting solutions seeking to minimize their energy footprint.
Upgrade Potential
The A5 offers a balanced upgrade path:
- Two DDR4 SODIMM slots, supporting up to 64 GB
- One M.2 NVMe slot (PCIe 3.0)
- One SATA connector for a 2.5” SSD or HDD (bracket and cable included)
For optimal performance, it’s advisable to run your hypervisor on the SATA SSD while leveraging NVMe storage for virtual machines.
Networking and I/O
The inclusion of a 2.5 GbE network adapter provides excellent connectivity for your self-hosting network. However, the absence of dual Ethernet ports may limit certain configurations. Nonetheless, its USB 3.2 ports offer fast data transfer options.
Noise and Thermals
This mini PC operates quietly and maintains excellent thermal performance, even under load. Users can expect consistent performance without worrying about overheating.
Versatile Use Cases for Home Lab
