Socket AM4 micro-ATX board

The MSI B450M PRO-VDH PLUS is a micro-ATX motherboard built on the AMD B450 chipset for Socket AM4 processors. It accepts Ryzen first and second generation CPUs as well as Ryzen and Athlon models with Radeon Vega graphics. Dual-channel DDR4 memory runs up to 3466 MHz with a 64 GB maximum capacity. A single PCIe 3.0 x16 slot handles graphics expansion.

Straightforward installation with common pitfalls

The board drops into any micro-ATX or larger chassis using standard standoffs and the supplied I/O shield. One SATA cable and a CMOS battery are included in the box. Builders often forget to seat the 8-pin CPU power connector or to update the BIOS before installing a newer Ryzen processor, which can leave the system without POST.

Compatibility checks before purchase

Verify that your CPU cooler clears the VRM heatsink area on this compact layout. Confirm the power supply provides an 8-pin EPS connector for the CPU. Ensure your memory kit is DDR4 and does not exceed the 64 GB total limit across the two slots. Check that your case front-panel headers match the board pin-out for USB 2.0 and audio connections.

Questions about this item

How can I verify the Realtek ALC892 codec is delivering 7.1 channel audio after installing the board?

Connect speakers to the rear analogue jacks, open the Realtek control panel in Windows, and run the 7.1 speaker test; all eight channels should play distinct tones if the codec is active.

Which accessories are included with the motherboard and what must I source myself?

The box contains the board, a CMOS battery, one SATA cable and the rear I/O shield; you must supply a Socket AM4 CPU, DDR4 memory modules, storage drives and a power supply.

Should I choose a Ryzen 1st/2nd generation CPU or a Ryzen with Radeon Vega graphics for full PCIe 3.0 x16 speed?

Ryzen 1st and 2nd generation processors run the primary slot at x16, while Ryzen and Athlon APUs with Radeon Vega graphics limit it to x8 or x4 respectively.
