The Prime B450M-A AM4 Micro-ATX Motherboard from Asus is built on the AMD B450 chipset supporting first- and second-generation socket AM4 AMD Ryzen processors. It has four memory slots, which can accommodate up to 64GB of DDR4 RAM at speeds of up to 3200 MHz when overclocked. For storage, there are six SATA III ports and one M.2 slot that supports both SATA and PCIe 3.0 x4 interface for speeds of up to 32 Gb/s when used with an appropriate M.2 drive. While it's equipped with VGA, DVI-D, and HDMI ports for integrated graphics, this motherboard also has one PCIe 3.0 x16 slot for a dedicated GPU as well as two PCIe 2.0 x1 slots for other PCIe-based hardware. Other noteworthy integrated features include Realtek ALC 887-VD2 8-channel HD audio, Realtek 8111H Gigabit LAN, and Asus Aura RGB lighting.
I got this on a really good special, and it just works. BIOS is easy to navigate, plenty of USB3 ports on back, runs quickly and no glitches or problems.
