MSI B450M Pro-M2 and B450M Pro-VDH

Last up from MSI is a pair of microATX motherboards from the Pro series of motherboards, the B450M Pro-M2 and B450M Pro-VDH. Both models share the same black PCB with brownish traces and tracks, while the B450M Pro-VDH makes use of a heatsink on the CPU section of the power delivery, whereas the B450M Pro-M2 omits power delivery heatsinks completely. Both have a square black metallic chipset heatsink with a fin array.

Both models have a full-length PCIe 3.0 x16 slot with both featuring metal reinforcement; the B450M Pro-VDH having the most predominant looking of the two. Also included on both is a pair of PCIe 2.0 x1 slots for expansion cards. The Pro series microATX pairing have four RAM slots supporting up to DDR4-3466 memory and have the ability to support up to 64 GB. ECC and non-ECC modules are both supported, albeit with installed ECC memory operating in non-ECC mode.

Storage wise, both boards have a total of four SATA 6 Gbps ports with the ports on the B450M Pro-M2 all featuring straight angled connectors, and the B450M Pro-VDH having two right-angled and two straight angled connectors. Both models have a single M.2 slot capable of supporting both PCIe 3.0 x4 and SATA M.2 2280 (22 x 80 mm) SSDs.

While both virtually identical in terms of overall specifications, the main difference comes on the rear panel. Both feature four USB 3.1 5 Gbps Type-A ports and two USB 2.0 ports; the B450M Pro-VDH has an additional two USB 2.0 ports giving it a total of four. Both boards have DVI-D and HDMI 1.4 video outputs, as well as a PS/2 keyboard and mouse combo port. The three 3.5 mm audio jacks on the B450M Pro-M2 is provided thanks to a Realtek ALC887 audio codec, whereas the B450M Pro-VDH utilizes a slightly more premium Realtek ALC892 codec. The LAN ports on both models are controlled by a Realtek 8111H Gigabit LAN controller.

Users looking to make the most of their new Ryzen 1st or 2nd generation processors, or even one of the Ryzen APUs with integrated Vega graphics cores without all the gaming-themed stylings and RGB could potentially save a bit of budget by opting for a Pro series board. While pricing hasn’t been unveiled as of yet, the B450M Pro-VDH is likely to cost a little bit more than the B450M Pro-M2 which is set to retail for $69.99 due to a slightly higher-grade audio codec and the M2 having no power delivery heatsinks supplied.

    It might have been more clear what point you were making if you had replied "The systems also support ...".

    The way it's presented in the table, though, it appears as if you are saying the older chipsets themselves do not support StoreMI, which is not true.

    Seemed perfectly understandable to me. And if you know one thing about StoreMi, you know what the chart refers to. It's just software after all. Reply

    Less-savvy readers might get an incorrect impression and come away with the sense that they need to "buy up" to use StoreMI at all. Reply

    Hey guys, whats the best option between the asrock b450 itx and the msi b450i ? The msi seems to be missing one fan header and usb 3.1 gen 2 compared to the asrock but the msi may have better VRMs...It also supports 3000mhz ram. I don't know what to choose, some have said that asrock b450 itx is not good (VRMs wise), i intend to OC my ryzen 2600 so VRMs are important

    Thanks !

    15000 words with a couple of hours to edit. Always going to be the odd one or two typos. Reply

    Its still there. Pity. Others may think it is correct. Reply

    Your summary table based on features does not currently list the ASUS mITX board under those with 2 M.2 slots. Reply

    Signed up to point that out. Needs to be fixed. It’s the only ITX board supporting 2x which sets it’s apart form the competition Reply
