Description
Built on the AMD B450 chipset, the MSI B450-A PRO MAX AM4 ATX Motherboard supports 3rd generation AMD Ryzen processors with the AM4 socket. Its four memory slots support a max of 64GB of DDR4 RAM that can be overclocked up to 4133 MHz. For storage, there are six SATA III ports as well as a M.2 slot utilizing the PCIe 3.0 x4 interface. While the motherboard is equipped with DVI-D, VGA, and HDMI outputs for integrated graphics, it also has a PCIe 3.0 x16 slot for a dedicated graphics card. Other notable integrated features include Realtek ALC 892 7.1-Channel HD Audio and Realtek 8111H Gigabit LAN. This motherboard features PCIe steel armor to protect GPUs from bending and EMI. Equipped with Core Boost, DDR4 Boost, Turbo M.2, and a USB 3.2 Gen 2 connector, the B450-A PRO MAX provides the performance you need to build your own gaming rig.
Please note that this motherboard does not currently support the AMD Ryzen 5000 series processors at this time. Support will be added through a BIOS update later in January, 2021.

Needed to upgrade 8 year old computer ( in computer years 8 is ancient), was getting extremely slow, started getting a few quirks during operation and the VRMs never worked correctly on the old motherboard. After assembly the computer ran quiet, fast and the VRMs work as they should. I purchased the motherboard, CPU and memory from B&H. The build; MSI B450-A Pro Max motherboard CPU AMD Ryzen 3 3200G 32 GB Memory Crucial Ballistix 3200MHz Excellent compatibility with memory running at advertised speed and no negatives so far.

Excellent price point and straight forward board for my first build. USB-C would be nice, but again it’s a great board for beginners/budget builds.

I’ve ordered from b&h a small handful of times. They’ve always done right by me and they always have average or below prices (in my experience) which is awesome. As for the B450-A Pro. It’s a great entry MB, I used one for my first build and bought a second for my brother to start his. Great quality and no issues with mine a little over a year in. My one gripe would be with there being no onboard usb-c port (should be standard these days) But for a little extra money and a new part you can still utilize usb-c. All in all very satisfied.
