AMD Ryzen 5 PRO 5655G Business Computers – Built in the UK
The AMD Ryzen 5 mATX Desktop PC is a six-core business and home office desktop PC for everyday productivity, multi-tasking and dual-monitor desk work.
Among Ryzen 5 PRO 5655G business computers, this build is a practical Micro-ATX choice. It uses the Ryzen 5 PRO 5655G processor with integrated AMD Radeon Graphics, so it needs no separate graphics card to drive monitors from the motherboard’s DisplayPort and HDMI outputs. The processor has six cores and 12 threads for a wide variety of tasks. It is built to order in a black Contour LP-2001 mini tower around a Micro-ATX motherboard, which makes it a practical choice for home offices, small businesses and general desk-based work. Whether you keep the specification as shown or change parts in the configurator, these Ryzen 5 PRO 5655G business computers are tested before they leave our UK workshop.
The AMD Ryzen 5 mATX Desktop PC is built on an AMD Ryzen 5 PRO 5655G processor (6 cores, 12 threads, 3.9GHz base and 4.4GHz maximum turbo) with integrated AMD Radeon Graphics, 16GB of DDR4 3200MHz memory in a dual-channel 2 x 8GB kit and a 500GB M.2 PCIe 4.0 NVMe SSD. It uses a Gigabyte A520M H ARGB Micro-ATX motherboard in a Contour LP-2001 Black case with a Contour 300W ATX power supply, and Wi-Fi 5 and Bluetooth 4 are provided by a PCIe card. Microsoft Windows 11 Home is supplied genuine and pre-installed, and the system carries a 3-year parts and labour warranty.
Six cores and 12 threads from the Ryzen 5 PRO 5655G
The AMD Ryzen 5 PRO 5655G is an AM4 processor with a 3.9GHz base clock, a 4.4GHz maximum turbo clock and 16MB of L3 cache. With 12 threads across its six cores, it helps when office applications, browser tabs and background tasks all run at the same time. The processor is cooled by the AMD stock CPU cooler, so the system is air-cooled with no liquid cooling to maintain.
Memory and storage for a responsive desktop
The system has 16GB of DDR4 3200MHz memory in a dual-channel 2 x 8GB kit, which gives room to keep an office suite, many browser tabs and a video call open together. The Gigabyte A520M H ARGB has two DIMM slots and supports up to 64GB, so both slots are used in this build and a later increase means replacing the modules.
The 500GB M.2 PCIe 4.0 NVMe SSD holds Windows and your applications. The A520M H ARGB has a PCIe 3.0 x4 M.2 slot, so the drive runs at PCIe 3.0 speeds, up to roughly 3,500MB/s, which is still much quicker than a traditional hard disk for starting Windows and opening files. For extra capacity the board has four SATA 6Gb/s ports, all free, and the case has mounts for one 3.5in and two 2.5in drives. No optical drive is fitted.
Integrated Radeon graphics and dual-monitor output
The Ryzen 5 PRO 5655G includes integrated AMD Radeon Graphics, so no graphics card is needed for office work. The motherboard provides one DisplayPort 1.4 and one HDMI 2.1 output, which lets you connect two monitors directly. That suits a spreadsheet and email layout on a pair of modern displays. The integrated graphics accelerate productivity software and handle casual games, but this is not a system for demanding 3D work.
Contour LP-2001 mini tower case
The build uses the Contour LP-2001 in black, a mini tower with a solid steel body measuring 365mm deep, 170mm wide and 345mm high. One 80mm rear fan is pre-installed. Power comes from a Contour 300W ATX power supply. The front panel has two USB 3.0 ports, two USB 2.0 ports, a headphone jack and a microphone jack.
Wi-Fi 5, Gigabit Ethernet and audio
A 1200Mbps 11ac dual-band PCIe Wi-Fi 5 card provides wireless networking with Bluetooth 4, and the motherboard has a Realtek 1GbE LAN port for wired networks. The front panel USB ports cover keyboards, mice, webcams, printers and storage. Audio is High Definition 7.1 from Realtek onboard audio. The board also has one PCIe 3.0 x16 slot and one PCIe 3.0 x1 slot.
Ideal for
- Home office workers who need a reliable desktop for documents, email and video calls
- Small businesses equipping staff desks with a consistent, easily supported PC
- Dual-monitor office setups using the DisplayPort and HDMI outputs
- Family and home computing for web browsing, streaming video and homework
- Anyone replacing an older desktop who wants six cores, 16GB of memory and an NVMe SSD
Among Ryzen 5 PRO 5655G business computers, this build brings six cores, 16GB of DDR4 memory, an NVMe SSD and Windows 11 Home into a compact Micro-ATX build for home offices, small businesses and family desks. The configurator only shows compatible options, and the availability of some options may change depending on earlier component choices. No keyboard or mouse is included, so use the accessory links below for monitors, keyboards and mice, webcams and cables.
Built to order and tested in the UK by Punch Technology, every system comes with a 3-year parts and labour warranty, backed by over 30 years of PC building experience. The estimated lead time for your configuration is shown when you order.

What is the AMD Ryzen 5 mATX Desktop PC best for?
The AMD Ryzen 5 mATX Desktop PC is primarily a business and home office desktop for document work, email, web-based tools, video calls and general multi-tasking. Six cores and 12 threads, with 16GB of dual-channel memory, leave room to keep several applications open at once. Windows 11 Home is installed, and Windows 11 Professional can be chosen in the configurator for business use.
Its limits are set by the integrated AMD Radeon Graphics and the 500GB SSD. Heavy 3D, rendering or video editing work calls for a system with a dedicated graphics card. Large archives are better kept on the free SATA ports and drive mounts or on network storage. For day-to-day office and home use, the DisplayPort and HDMI outputs, Wi-Fi 5 and Gigabit Ethernet cover the usual connections.
Where does the AMD Ryzen 5 mATX Desktop PC sit in the range?
Below it, the Punch SlimStation Essential Ryzen 5 PRO 5655G Compact Desktop PC lists the same AMD Ryzen 5 PRO 5655G, 16GB of DDR4 and 500GB NVMe SSD in a compact desktop. The Home Office Ryzen 5 PRO 5655G Desktop PC also lists the same processor, memory and SSD, so compare the two pages for differences in the case and other parts. The Value Ultra 5 Small Business PC moves to an Intel Core Ultra 5 225 with 8GB of DDR5 and a 256GB SSD for lighter workloads. Above it, the Core Ultra Small Form Factor Education PC pairs an Intel Core Ultra 5 225 with 16GB of DDR5 and a 256GB SSD in a small form factor.
Frequently Asked Questions
What software can the AMD Ryzen 5 mATX Desktop PC run?
It runs Windows 11 Home and everyday business and home office software, including office suites, web browsers, email, video conferencing and accounting packages. Six cores, 12 threads and 16GB of DDR4 memory let several of these run together. The integrated AMD Radeon Graphics also accelerate supported productivity software. It is not intended for demanding 3D, rendering or video editing work.
Does the AMD Ryzen 5 mATX Desktop PC have Wi-Fi and Bluetooth?
Yes, a 1200Mbps 11ac dual-band PCIe card provides Wi-Fi 5 and Bluetooth 4. The motherboard also has a Realtek 1GbE LAN port if you prefer a wired connection.
How many monitors can I connect to the AMD Ryzen 5 mATX Desktop PC?
You can connect two monitors directly to the motherboard using the integrated graphics. The board has one DisplayPort 1.4 and one HDMI 2.1 output, so a pair of modern displays works without a separate graphics card.
Can I upgrade the memory or storage later?
Yes, within limits. The motherboard supports up to 64GB of DDR4 but has two DIMM slots, both used by the 2 x 8GB kit, so more memory means replacing the modules. The single M.2 slot holds the SSD. The four SATA 6Gb/s ports are free, and the case has mounts for one 3.5in and two 2.5in drives for extra storage.
Who is this PC best suited for?
It suits home office workers, small businesses and families who want a dependable desktop for documents, email, web-based tools and video calls. It is a good fit for anyone setting up a dual-monitor desk without a separate graphics card. Buyers who need dedicated graphics power for 3D or rendering work should look at a system with a graphics card.
Can I choose Windows 11 Pro instead of Windows 11 Home?
Yes, you can upgrade to Windows 11 Professional in the configurator. Pro suits business use because it adds BitLocker drive encryption, Remote Desktop and domain join. Either edition is supplied genuine and pre-installed.
