The ASRock DeskMini X300/2.5G is a 1.92-litre barebone mini PC for AMD Ryzen AM4 APUs, designed for system builders who want a compact office, HTPC or light-duty workstation that they configure themselves. This listing is part number 90BXG4901-A10GA0W; it ships without CPU, RAM, storage or operating system.
Inside the 155 x 155 x 80 mm chassis you get two DDR4 SO-DIMM slots (up to 128GB), two PCIe Gen3 x4 M.2 slots and two 2.5-inch SATA bays. The /2.5G version upgrades networking to Realtek 2.5GbE, and HDMI, DisplayPort and VGA outputs can drive three displays at once. A 120W power adapter is included. Typically in stock with fast delivery across Cyprus.
Compatibility Note
Barebone — no CPU, RAM, SSD, CPU cooler or OS included. Supports only AMD AM4 APUs with integrated graphics (Ryzen 5000G / 4000G / 3000G / 2000G) up to 65W — Ryzen CPUs without graphics (e.g. 5600X, 5800X3D) will not output video, as there is no graphics card slot. Memory must be DDR4 SO-DIMM (laptop-size). You need an AM4 cooler no taller than 46 mm. Wi-Fi is not included (optional M.2 Key E 2230 module).

Frequently Asked Questions
Can I use a Ryzen 7 5800X in the DeskMini X300/2.5G?
No video output would be available, because the DeskMini has no graphics card slot. Use a Ryzen APU with integrated graphics such as the Ryzen 5 5600G or Ryzen 7 5700G.
Does the DeskMini X300/2.5G include a CPU cooler?
No. You need an AM4 low-profile cooler no taller than 46 mm — check the cooler height before ordering.
What is the difference between the DeskMini X300/2.5G and the DeskMini X600?
The X300 uses AM4 APUs with DDR4 SO-DIMM, while the DeskMini X600 uses AM5 Ryzen 8000G/7000 with DDR5 SO-DIMM for newer performance.
What do I need to know before buying the DeskMini X300/2.5G (90BXG4901-A10GA0W)?
It is a barebone: add an AM4 APU (up to 65W), a low-profile cooler, DDR4 SO-DIMM memory, an M.2 or 2.5-inch drive and an operating system.
Singular Expert Insight
The DeskMini X300/2.5G is one of the most cost-effective ways to build a tiny, quiet office or media PC: a Ryzen 5 5600G, 16GB DDR4 SO-DIMM and a 500GB NVMe drive create a capable triple-monitor system. If you want DDR5 and newer Ryzen 8000G graphics, choose the DeskMini X600 instead. Add storage from our
internal SSDs range.
