For those looking to build a Ryzen 7 3700X or Ryzen 7 3800X system, you’ll likely have two main questions: 1) Do I go for an X570 motherboard that’s specifically designed for the new Ryzen 3000 series chips, and supports PCIe 4.0? Or, 2) Do I decide to use a previous generation X470 or B450 motherboard, all of which are compatible with the new Zen 2 processors by AMD?

Each option has its benefits and drawbacks. With an X570 motherboard you are future-proofing your build, and benefitting from the blisteringly fast new PCIe 4.0 interface. However, X570 motherboards are priced very steep in comparison to the older chipsets. Opting for a B450 or X470 motherboard for the Ryzen 7 3700X or 3800X, you can pick from a range of more affordable options, still with exceptional VRM quality and performance.

All B450 and X470 chipset motherboards support Ryzen Zen 2 processors, and all they require for compatibility is a BIOS update, so you’re going to want a board that offers BIOS Flashback, or that already has the latest compatible BIOS out of the box.

Although the X570 is the latest and greatest chipset for Zen 2, if you don’t plan on overclocking the 3700X or 3800X, we suggest you choose a B450 or X470 motherboard for your next build. If you do plan on overclocking and prefer a bit more future-proofing, check out our motherboard roundup for the Ryzen 9 3950X. If you’re still working out whether to pick the 3700X or 3800X, we recommend checking out this guide.

The Ryzen 7 3700X and 3800X have far more efficient power consumption and lower TDP (65W) than the second generation of Ryzen. For example, an overclocked Ryzen 7 3800X consumes less power than a conservatively overclocked Ryzen 7 2700X. Thus, any B450 or X470 motherboard capable of housing an overclocked Ryzen 7 2700X is more than capable of running the new 3700X and 3800X.

Now let’s take a look at the best motherboards for 3700X & 3800X builds, drawing from not just X570 chipset motherboards but also the B450 and X470 chipsets that support the new Ryzen 3000 processors including the Ryzen 7 3700X.

Best Overall B450 Motherboard for Ryzen 7 3700X & 3800X

ASUS-B450-F-ROG-Strix-Gaming

B450 chipset motherboards are proving to be more than enough for the Ryzen 7 3700X, with excellent VRM quality and design for an affordable price. If you’re not looking to overclock the Ryzen 7 3700X and want a capable budget B450 motherboard, we recommend the Asus ROG STRIX B450-F.

The STRIX B450-F offers a solid 8 Phase (6+2) VRM, at an incredibly reasonable price. Many VRM Tier lists indicate the STRIX B450-F was sufficient for overclocking the 2700x, which has much higher power consumption than the 3700X and 3800X and makes it the most sensible choice for conservative budgets.

ASRock X470 Taichi for Ryzen 7 3700X 3800X

Two X470 motherboards are considered best-in-class for the X470 chipset, each with awe-inspiring VRM quality and chock-full of features. Enter, the ASRock X470 Taichi Ultimate and ASUS Crosshair VII Hero. The Taichi Ultimate is significantly cheaper than the Hero, so it gets our recommendation for overclocking with the 3700X and 3800X on an X470 board.

The X470 Taichi features a 12 phase VRM (6 phases using doublers) for the VCore and a 4 phase VRM for the SoC. With top-tier VRM, this X470 motherboard is capable of extreme overclocking even a Ryzen 9 3950X!

Features include 2x M.2 slots, of which one has a heat shield, USB 3.1 Gen 2 connectivity, Wi-Fi, and a POST-Code readout for overclocking. The only notable negative is where the X470 Taichi does feature Wi-Fi, it is rated at 433MBps, which is not great for 2020.

The Taichi Ultimate is by far the best value high-end motherboard for overclocking any of the 3000 Series Zen 2 processors on an X470 platform.


Best mini-ITX motherboard for Ryzen 7 3700X and 3800X SFF Builds

msi-performance-gaming-b450i-gaming-plus-ac

If you’re after a mini-ITX motherboard capable of extreme overclocking the 3700X/3800X in a small form factor system, then you’re in luck. The MSI B450I Gaming Plus AC is regarded as the best B450 ITX motherboard with a fantastic VRM, decent BIOS, and great features, including a DisplayPort (missing from other ITX B450 motherboards), integrated Wi-Fi, 4x SATA, and M.2 support.

Unfortunately, the B450I Gaming Plus cannot apply a voltage offset, which is not ideal for XFR2 and temperature management. That said, the physical VRM layout on this ITX motherboard outweighs this drawback and secures our firm recommendation for the best B450 mini-ITX motherboard for the Ryzen 7 3700X and 3800X.

ASUS-ROG-Crosshair-VIII-Hero-Wifi

The Asus Crosshair VIII Hero. Asus is doing something right here with their jaw-dropping power delivery, at a significantly lower price than both the MSI X570 Godlike and Gigabyte X570 Aorus Xtreme.

The Crosshair VIII is a much more sensible option for prosumers and enthusiasts interested in extreme overclocking with Zen 2 processors, which also helps to keep the overall size of your system down at a standard ATX form factor vs. the Extended-ATX Godlike and Aorus Xtreme. With VRM performance this competitive, it almost makes you wonder whether it’s even remotely justifiable to spend around ~$130 more for the Godlike or Aorus Xtreme.
