Best Motherboard for Ryzen 9 3900x

Introduction

With the launch of the Ryzen 9 3900X processor, AMD’s cutting-edge design has tremendous potential for 2019 and beyond. However, you can’t make use of this power without a motherboard that is up to the task. That’s why we’ve rounded up all of our favorite X570 motherboards on the market right now.

There are a couple of X570 boards in the list that’s well worth checking out, although most of our picks lean toward more affordable options — they’re not all super-high-end $500+ motherboards.

AMD is laying out a fantastic and brave path into production and we expect it to be just as good for gamers and enthusiasts alike. The new Zen 2 design brings much-needed competition to the market and forces Intel’s hand when it comes to increasing core counts. Thanks in part to AMD, we’re seeing $500 CPUs with eight cores in 2019!

It all starts here, though: Ryzen 9 3900X is an incredible processor for both content creation and gaming — it just happens to be a bit of an oddball for each. For gaming, we feel the Ryzen 9 3900X is a better choice and that’s reflected in our list below. However, it’s still an amazing processor and deserves to be on this list as one of 2019’s best CPUs.

If you’re looking at building a new system with all the latest parts, then this is the guide for you. You’ll find our complete list of recommended motherboards according to specific budgets and needs. Whether you’re building a high-end gaming PC with the very best components or are simply looking for a great AMD motherboard on an X570 chipset board, we’ve got your back covered!

Quick Shopping Tips for Ryzen 9 3900X motherboards

The AMD X570 platform is more expensive than the old AM4 models. That’s just a fact of life. So if you’re on a tight budget, we suggest going for an older-but-great Ryzen 2nd Gen (non-X) motherboard and pairing that with one of Intel Core i5 9600K or Core i9 9900K CPUs.

On a related note, in the pre-Ryzen days, AMD always offered a full range of CPUs that came with an included motherboard. However, these days, you have to buy CPU+mobo combos from AMD or third parties — motherboards are no longer typically included in the box for Ryzen chips.

Power Phases of motherboards

Power phases determine how many “faucets” of power you will have available. Most boards today come with 8 or 10 power phases, but some can go up to 13 or more, especially among higher-end models.

For gaming PCs (and even for office/content production rigs), we recommend not going beyond 10 power phases. More phases are not always better — they may help for extreme overclocking, but for more traditional builds, go with 8-10+2 power phases. Don’t cheap out on motherboard Thermal Interface Material (TIM)

Many cheaper motherboards come with cheap thermal interface material that is less efficient than others on the market. This is due to cost savings on the part of manufacturers.

Sockets of Motherboards

There are four socket types to consider in 2019: LGA 1151 (Coffee Lake, Kaby Lake), LGA 2066 (Skylake-X), TR4 (Threadripper 2nd gen), and AMD AM4 (Ryzen & Threadripper 1st gen).

For gaming PCs, Socket AM4 is the only platform to consider. AM4 is the future and it’s going nowhere anytime soon, so anyone who builds a Ryzen-based PC now or in 2019 will likely use this socket type for years to come, as Ryzen 3rd gen processors are expected to drop on this foundation.

For content production PCs (i.e., video editing), you can build on any socket type you want. That said, we prefer LGA 2066 and TR4 for top-notch production performance and stability.

Expansion Slots of motherboard

There are three main expansion slots to consider: PCIe 3.0 x16 (used for graphics cards), M.2 NVMe, and PCI-E 1x (used for WiFi cards, sound cards etc.)

The second most important consideration after CPU socket type is whether you need an AM4 motherboard that has 2 or more PCIe 3.0 x16 slots.

Modern graphics cards come with two or more PCIe 3.0 connections, meaning that even if you have a high-end (i.e., non-mainstream) card like the RTX 2080 ti, it will benefit from using an AM4 socket motherboard with at least 2 PCIe 3.0 16x sockets on board.

RAM Slots of motherboard

There are two main types of RAM slots: DDR4 (used for Ryzen CPUs) and DDR3 (used for older Intel CPUs). Since there’s no real difference beyond compatibility, we recommend sticking to one standard or the other if you’re building a new gaming system. If you buy all Ryzen-compatible components, you won’t need to worry about compatibility.

Aesthetics of Motherboard

Most people don’t care about the look of their motherboard, but there are some components that might clash with the rest of your build if you’re building a custom rig (i.e., narrow bezels on monitors or cases, all-black components). You should either not worry about it or do adequate research before buying.
