No Picture

The ASUS PRIME B650M-A II-CSM is a compact, micro ATX motherboard for AMD's new AM5 socket and Ryzen 7000 Series processors. It sacrifices some of the expansion capacity that a larger motherboard offers, but still supports up to 128GB of DDR5 memory and multiple SATA and M.2 drives. Three PCI-Express 4.0 slots are also present, with one supporting full x16 speed for a video card and the other at x1 for small expansion cards.

For external connectivity, this board has basic analog audio outputs, 2.5Gb Ethernet, and eight USB Type-A ports of varying speeds. There are also HDMI, DisplayPort, and VGA outputs for use with the graphics built into AMD's Ryzen processors, though most users will want to add a dedicated video card for improved performance.

With no built-in WiFi or Bluetooth, this is a great motherboard option for users who need to comply with government or corporate limits on wireless connectivity.
