The ASUS PRIME B450M-A II is a Micro-ATX motherboard that brings the AMD B450 chipset to builders who need steady performance in a small case. Designed for the AM4 socket, it works with first, second, and third generation Ryzen or Athlon processors, so you can start with a budget chip and upgrade later without changing the board.

Four DIMM slots let you install up to 128 GB of DDR4 memory, and speeds can reach 4400 MHz when you overclock. For storage, the board combines one M.2 slot for a fast NVMe drive with six SATA III ports for traditional hard drives or 2.5 inch SSDs. RAID 0, 1, and 10 are supported, giving you options for speed, redundancy, or both.

Expansion is straightforward. A full-length PCIe 3.0 x16 slot is ready for a dedicated graphics card, and two PCIe 2.0 x1 slots can hold capture cards, sound cards, or other add-ons. On the rear panel you get USB 3.2 Gen 2 ports that move data at up to 10 Gb per second, plus HDMI, DVI-D, and VGA outputs for systems that rely on integrated graphics. Networking comes from a Realtek Gigabit Ethernet controller, while the Realtek ALC887/897 codec delivers 7.1-channel audio for movies, music, and games.

For anyone who likes to tune or future-proof a build, the BIOS FlashBack button makes UEFI updates possible without installing a CPU or memory first. Whether you are setting up a compact gaming tower, a quiet home office PC, or a small business workstation, the PRIME B450M-A II provides reliable performance and the essential connectivity you need.
