    My only gripe with it so far is the voltages... They're too high. Even when updated to the latest BIOS (AGESA 1.0.0.3), voltages nearly reach 1.5V. Setting a -0.1V offset limits the CPU's capability, sadly. For now I'd rather keep it as is, and if the high voltage kills it, it's either MSI's or AMD's problem to fix.

    I really like this board ... I've got nothing to nag. Two m.2-Ports, Bios-Flash-button and VR-ready-USB3-ports are a nice bonus.

    from completed build Breaky Boi

    I heard everyone praising MSI's B450 boards, this one was among the best rated, solit VRMs, as far as I know. I was thinking about the mini ITX format (better fit on my table), but I changed my mind last minute. Only thing I'm concerned about is the fact that in bios it says that the Vcore is at 1.465 Volts. That seems crazy high, but in windows it goes down by a looot. while idling it's at like 1.20. I updated the BIOS to the latest one (09.20.2019).

    from completed build Air 3700x Gaming rig

    Solid motherboard for the price. Has Ryzen 3000 support out of the box, Bios Flashback via USB, lots of storage options (2 M.2 + 4 SATA), 2 PCIE slots (second one is disabled if you insert a second M.2), very good VRMs and cooling solution even for Ryzen 3000. Click Bios is pretty good and has most CPU option available with their standard names instead of hiding or renaming them like many other manufacturers do. Highly recommended for small form factor builds.
