Overview

The ASRock DeskMini X300W is a barebone mini PC platform built around the AMD X300 chipset, designed for users who want a compact desktop without sacrificing the ability to choose their own components. Measuring just 155 x 155 x 80mm, it occupies a fraction of the space of a traditional tower while still supporting AMD AM4 Renoir, Picasso, and Raven Ridge APUs up to 65W. With two SO-DIMM DDR4 slots capable of handling up to 64GB of memory and a generous array of storage connections — two M.2 slots and two SATA3 ports — the DeskMini X300W punches well above its weight class in terms of expandability.

Connectivity is well covered with three USB 3.2 ports, one USB 2.0 port, Gigabit Ethernet, and an M.2 Key E slot ready for a Wi-Fi and Bluetooth module. Display flexibility is another highlight, with HDMI, DisplayPort, and D-Sub outputs letting you connect virtually any monitor. Whether you are building a silent home-theater PC, a compact office workstation, or a space-saving development machine, the DeskMini X300W provides a solid and configurable foundation. Made in Taiwan, it reflects ASRock's established reputation for reliable, well-engineered small-form-factor systems.
