Choosing the Right B450 Motherboard

While there are over twenty-five motherboards to select from on the B450 chipset, finding the right one with the right balance of features can be somewhat confusing. Selecting based on certain criteria can help narrow down between features such as dual M.2, integrated WiFi and pricing; some shine above others in the specifications whereas others may not have a specific desired feature.

The B450 chipset is essentially a B350 first generation refresh which has given manufacturers the opportunity to refine and define; for example GIGABYTE has focused their attention on specifically on defining their Aorus gaming brand to users and has used the B450 chipset to implement the new naming schemes. Other vendors have made slight aesthetic adjustments, while others have added more premium componentry to their offerings in exchange for a slightly higher MSRP; or in a lot of cases, remained with the same pricing structure.

Each vendor seems to have a good range of products on offer, from $70 to $130, with at least one board in the range with Intel Ethernet, Intel Wi-Fi, and the top end codec. In order to get all three, it looks like the minimum price will be $120.

    Glad to see more options in the mATX range with two M.2 slots, not just from AsRock this time around. My next rig will either be based on the AsRock B450M Pro4 or one of the MSI B450M Mortar boards. Will wait for actual VRM setup and overclocking results / general tests to see which one will be it. I had motherboards from both manufacturers and was pleased with both. MSI has the advantage of offering PCIe M.2 options for both slots as well as SATA. One question regarding that: if I install a 3.0 PCIe x2 M.2 SSD into a 2.0 PCIe x4 slot, what will be the speed ramifications? Can it only use 2.0 PCIe x2 or can it use the full x4, thus being similar in speed to a native 3.0 PCIe x2 setup? :) Still waiting on mATX x470 mainboards. Reply
  • Outlander_04 - Tuesday, July 31, 2018 - link

    .3.0 x 2 is the same speed as 2.0 x 4 Reply
  • DanNeely - Tuesday, July 31, 2018 - link

    Except that a 3.0 x2 drive is almost certainly x2 because it only has 2 PCIe lanes (cutting down on them is one of the ways the cheaper drives pinch pennies), which means it will be connected at 2.0 x2; at that point you might as well just use a SATA drive and save a bit more money. Reply

    Thanks for providing an answer to my actual question. :) Reply
  • AdrianB1 - Tuesday, July 31, 2018 - link

    You will get a 2 lane PCIe 2.0 connection, that means 1 GB/s. This is 1/4 of a PCIe 3.0 4-lane usual NVME drive, but real life you may get closer to 80% of the performance. Reply

    Finally some budget boards with solid VRMs. Reply
  • skpetic - Tuesday, July 31, 2018 - link

    There are some seriously shady stuff going on with VRMS om X470 og B450. Check out Buildzoid on youtube. Asus B450 STRIX ITX board is single phase for SoC. Several of the Gigabyte B450 and X470 boards in reality have half the advertised amount of phases or are using doublers:

    hahaha... no

    Asus with the absolute trash tier VRM heatsinks
    AsRock with fake phases
    Gigabyte with fake phases and trash VRM heatsinks
    MSI with no Vcore offset

    It looks like the price link to the "TUF B450-Plus Gaming" is going to an amazon search for "ASRock B450M Pro4" Reply
