The AMD Ryzen 9 3900X is a powerful processor, but it's only able to hit its full potential with a good motherboard. We rounded up some of the best motherboards to use with the processor.
Best X470
Staff pick
ASUS ROG Strix X470-F
It may be considered old school with X570 out, but the ASUS ASUS ROG Strix X470-F is a tried and trusted platform for AMD builds. You not only get a great UEFI BIOS with reliable, high-quality components for a great foundation, there's also RGB lighting, which is scientifically proven to improve frames-per-second figures.
Premium X570
ASUS ROG Strix X570-E
If you don't want to use older chipsets, you'll need an X570 motherboard that also brings additional benefits like PCIe 4.0 support and Wi-Fi 6. This ASUS board has Gen 4 M.2 slots capable of unidirectional transfer speeds up to 64 GB/s, and plenty of RGB lighting options to boot.
Budget B450
ASRock B450M Steel Legend
The B450 chipset is a little less advanced than the X470 and X570 siblings, but it's still worth considering for a new build. This board from ASRock supports Ryzen 3000 series CPUs and provides enough features for the 3900X.
Entry X570
ASUS Prime X570-P
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.
Enthusiast Build
ASUS ROG X570 Crosshair VIII Formula
Okay, time for the big one. This ASUS motherboard is a perfect match for the Ryzen 9 3900X. It houses plenty of features, including a heatsink block that can be connected to your custom water-cooling loop. It's quite literally insane.
Choosing the best X470 or X570 motherboard
Our recommendations here will work flawlessly with the Ryzen 9 3900X CPU. If you want to enjoy the best of what X470 has to offer (and you don't need PCIe 4.0), the ASUS Strix X470-F is still an excellent choice for most consumers, even providing room for stable overclocking.
X570 is the latest chipset from AMD to support Ryzen 3000 series processors, and there are numerous options available already. Still, our recommendation goes to the ASUS Prime X570-P, rocking PCIe 4.0 support, high-quality components, and a great BIOS.
