Overview

The ASRock AB350 Gaming-ITX/ac is a Mini-ITX motherboard built around the AMD B350 chipset, designed for compact AM4 socket builds. Released in July 2017, it has remained a popular choice for users who want to build a small-form-factor PC with Ryzen processors without sacrificing essential features.
This board packs two DDR4 memory slots supporting up to 32GB, with official support for speeds of 3466/3200/2933/2667/2400/2133MHz. Both ECC and non-ECC memory modules are compatible. A single PCIe 3.0 x16 slot handles graphics card installation, making it suitable for a compact gaming rig or a space-saving office desktop.
For connectivity, the AB350 Gaming-ITX/ac includes Intel Gigabit LAN and 802.11ac Wi-Fi on board, reducing cable clutter in small cases. When paired with an APU, two HDMI outputs are available for multi-display setups. This motherboard targets entry-level to mid-range Ryzen builds where cost efficiency and a small footprint matter more than maximum expansion.

Compatibility Guide

The AB350 Gaming-ITX/ac uses the AM4 socket, compatible with first and second-generation Ryzen processors. Newer CPU generations may require a BIOS update, so always check the official CPU support list before purchasing.
Memory support is limited to DDR4 with two slots, maxing out at 32GB. Because this is a Mini-ITX board, there are only two DIMM slots, so plan your capacity carefully — 16GB x 2 is a sensible configuration for most users. Both ECC and non-ECC modules are supported, which is a nice bonus for budget workstation builds.
The form factor is Mini-ITX, meaning it fits in compact cases. Expansion is limited to one PCIe 3.0 x16 slot, so multi-GPU setups are not possible. Storage options include a single M.2 slot (Key E type), which is important to note — this is not the standard Key M slot used by most NVMe SSDs.

Product Info

The AB350 Gaming-ITX/ac launched on July 12, 2017, positioning itself in the entry-to-mid tier of AMD motherboards. The B350 chipset is AMD's mainstream offering, and this board adds value with integrated 11ac Wi-Fi and Intel Gigabit LAN — features not always found at this price point.
Physical dimensions are 227 x 186 x 83 mm, weighing 780 g, which is standard for Mini-ITX boards and fits most small-form-factor cases. The warranty period is two years.

Best Use Cases

  • Compact PC builders who prioritize a small footprint over expansion options. The Mini-ITX form factor fits in tiny cases, and the built-in Wi-Fi keeps cable management simple. Not suitable for those who need multiple graphics cards or many internal drives.
  • Budget-conscious users building an AM4 system. The B350 chipset keeps costs down while still providing access to the Ryzen platform. Not ideal for enthusiasts who want to push high-end CPUs to their limits.
  • Office or media center PC builders who value space efficiency. Pairing with an APU enables dual HDMI output for multi-monitor productivity. Not recommended for users who need extensive internal storage expansion.

Things to Consider

This motherboard was released in 2017, so compatibility with newer AM4 CPUs like the Ryzen 5000 series may require a BIOS update. Verify the CPU support list on the official website before making a purchase decision.
The two memory slots limit future expansion, so choosing larger capacity modules from the start is wise. Additionally, the M.2 slot is Key E type, which differs from the standard Key M slot found on most NVMe SSDs — check your storage device compatibility carefully.
With only one PCIe x16 slot, adding multiple expansion cards such as capture cards or sound cards is not possible. If you need more expansion capability, an ATX-sized motherboard would be a better fit.

FAQ

Q: Can I use a Ryzen 5000 series CPU with this motherboard?
A: The AM4 socket is physically compatible, but a BIOS update is required. Check the official CPU support list and update to the latest BIOS before installation.
Q: What is the maximum memory capacity?
A: Two DDR4 slots support up to 32GB total.
Q: How many graphics cards can I install?
A: Only one, as there is a single PCIe 3.0 x16 slot. For multi-GPU configurations, consider an ATX motherboard instead.
