Designed for PC builders seeking a solid AM5 socket foundation, the MSI Pro B840M-B features the AMD B840 chipset to support latest-generation processors. Its Micro ATX form factor (226 × 243.8 mm) makes it easy to fit into compact cases without sacrificing essential features: dual-channel Non-ECC memory, RAID 0/1/10 support, and HDMI 2.1 output for high-definition display. The Realtek ALC897 audio chip delivers 7.1-channel sound, while the RGB LED connector allows for lighting customization. The AMI UEFI BIOS and wired Ethernet connectivity complete a setup designed for a reliable and scalable build.
