Best Motherboards for AMD Ryzen 9 3950X in 2021 — X570, B550

To get the most out of your Ryzen 3000 series CPU, you'll need to go with the X570, and this motherboard from ASUS is a great option. Not only do you get benefits like PCIe 4.0 support, high-quality components, and Wi-Fi 6, but also Gen 4 M.2 slots capable of unidirectional transfer speeds up to 64 GB/s, rapid LAN ports, and plenty of RGB lighting options to boot.

This B450 motherboard may not be as advanced as our other recommendations, but it's worth considering for a new build. It supports Ryzen 3000 CPUs, has more than enough features for the 3950X, but don't go expecting to push the system as far as more premium motherboards.

Mini-ITX boards are a whole different breed, thanks to vendors having to cram as much tech on larger motherboards onto a smaller PCB. Still, it's possible to create a capable, stable platform like this excellent example from ASUS. You've got 8+2 phase delivery with active VRM cooling alongside active chipset cooling. An excellent foundation for smaller builds.

While it's challenging to locate any budget-friendly X570 motherboards, this ASUS board is one that would suit someone who wants the latest chipset features on a more basic platform. It's got a lot going for it, too, with metal heatsinks for the VRMs and other high-quality components.

This is when things start to get a little more severe with the Crosshair VIII Formula from ASUS. It comes with plenty of features, including high-quality components for stable overclocking, as well as a heatsink block that can be connected to your custom water-cooling loop. It's quite literally insane.
