Socket AM4 platform for Ryzen builds

This Micro ATX motherboard uses the AMD B450 chipset and a Socket AM4 interface to support first, second and third generation Ryzen desktop processors including models with Radeon Vega Graphics. It provides a compact foundation for mainstream gaming or productivity systems that do not need a full size ATX board.

Memory and PCIe behaviour under load

Four DDR4 slots accept dual channel kits up to 128 GB running at speeds from 2667 to 3466 MHz, while the single PCIe 3.0 x16 slot operates at full x16 bandwidth with Ryzen CPUs and at x8 when an APU is installed. Sustained workloads stay stable thanks to the board’s power delivery design and the chipset’s thermal limits.

Storage and I/O interface limits

One M.2 slot and four SATA III ports share the B450 chipset lanes, so populating the M.2 socket can reduce available SATA connections depending on the drive type used. Rear I/O includes two USB 3.2 Gen1 ports, four USB 2.0 ports and a Realtek 8111H Gigabit LAN controller, while the Realtek ALC892/897 codec delivers 7.1 channel audio.

Questions about this item

How much heat and power does the B450M PRO-VDH MAX draw when running all day?

The board uses the AMD B450 chipset with a Realtek 8111H Gigabit LAN controller and Realtek ALC892/ALC897 audio codec; power draw and thermal output depend on the installed Ryzen processor and DDR4 memory configuration.

What components must I already own for the B450M PRO-VDH MAX to work?

You need a Socket AM4 Ryzen processor (1st, 2nd or 3rd generation), DDR4 memory modules up to 3466 MHz, a micro-ATX compatible case and a PSU with a 24-pin ATX and 8-pin CPU power connector.

Will the B450M PRO-VDH MAX run alongside my older SATA drives and PCIe 3.0 graphics card?

Yes, the board provides four SATA III ports and one PCIe 3.0 x16 slot that operates at x16 with 1st-3rd gen Ryzen CPUs or x8 with Ryzen APUs, so existing SATA SSDs, HDDs and PCIe 3.0 GPUs will function normally.
