Best Motherboard for Ryzen 9 3900x

PC builders can finally start building their highly awaited Zen 2 builds now that Ryzen 3000 processors, including the Best Motherboard for Ryzen 9 3900x, are starting to become widely available from retailers across the world. The Ryzen 9 3900X is expected to be their high-end, enthusiast-grade offering, with outstanding performance and benchmarks on paper. It will compete with Intel’s Core i9-9900K and i9-9900KS processors in 2019.

It’s critical for those looking to develop with the Best Motherboard for Ryzen 9 3900x to get the most performance out of this Zen 2, 7nm processor. – You’ll want to pair it with a capable CPU cooler for improved thermal efficiency, an X570 motherboard with decent VRM quality and features, Ryzen (B-die) optimized RAM, a decent power supply, and a PC case with strong airflow, as well as one that looks fantastic!

Best Motherboard for Ryzen 9 3900x

We’ll go through the best motherboards for Ryzen 9 3900X builds in this guide, covering a wide range of choices such as mini-ITX and micro-ATX motherboards for the 3900X, the best motherboards for overclocking the 3900X (despite little headroom for OC’ing – more on that later), and budget options.

If you’re building a Ryzen 9 3900X, we’re assuming you’ll want to go for a high-end, enthusiast-level model, which means you’ll want to use the new PCIe 4.0 standard and take advantage of the new PCIe 4.0 NVMe SSDs, which can reach speeds of up to 5Gb/s. As a result, aside from our budget portion, where we’ll have a B450 motherboard, we’ll be looking for motherboards with AMD Ryzen’s Zen 2 and the Ryzen 9 3900X latest X570 chipset.Even with the undervolt, the board still underperformed and overheated, so the B450-F Gaming is a poor match for the 3900X or 3950X, and frankly, it’s not any better with the Ryzen 7 2700X.

Is B450 good enough?

Yes, unless you want to massively overclock the Ryzen 3950X, it’s a decent match. A B450 Tomahawk Max is capable of running a Ryzen 9 3950X at full stock frequency, as well as light overclocking and Precision Boost Overdrive.

List of Best Motherboard for Ryzen 9 3900X

1.The best in the flagship Motherboard gaming  for Ryzen 9 3900X for PC

Looking at all of the flagship X570 motherboards that have been released so far, the Gigabyte X570 AORUS Xtreme is the only one that sticks out right now.

This motherboard is not only one of the most attractive X570 motherboards on the market, but it also has one of the most overkill VRMs with a solid heatsink, featuring a true 14-phase architecture, a first for any motherboard, period, as well as 70A smart power stages. The AORUS Xtreme, unlike the other flagship X570 motherboards, lacks one of those divisive active chipset cooling fans, which many PC builders despise.

If you intend on extreme overclocking the Ryzen 9 3900X, there are two 8-pin power connectors available, but if you don’t, you can use either one or the 8-pin and 4-pin connector.

This motherboard includes all of the features you’d expect from a flagship X570 motherboard for the Ryzen 9 3900X, including 10 GbE LAN, WiFi 6, internal and external transparent CMOS keys, a Dual BIOS, and socketed BIOS chips.

The Gigabyte X570 AORUS Xtreme, priced at just under $700, is hands down the best flagship and enthusiast X570 motherboard on the market, and if money is no object, pair the Ryzen 9 3900X with this great motherboard.

2.The Overall best Asus Motherboard gaming for AMD Ryen 9 3900X support PCIe 4.0

If you want the best X570 motherboard for your Ryzen 9 3900X build but don’t want to pay flagship motherboard prices (e.g. the ASRock X570 AQUA, which costs $1000), then one of the mid-range, performance-oriented X570 motherboards – such as the ASUS ROG Crosshair VIII Hero, MSI Meg Ace, Gigabyte X570 AORUS Master, and ASRock X570 Taichi – will suffice. On paper, youtuber ‘Buildzoid’ recently did a video on the X570 flagship motherboards, claiming that all of them are nearly identical in terms of requirements and VRM quality (basically overkill) – and that whichever one you choose, you can’t go wrong.

With that said, if we had to choose between the flagship X570 motherboards, we’d go with the ASUS Crosshair VIII Hero WiFi because it has the most user-friendly BIOS for tuning the 3900X (in our opinion).

The Crosshair VIII Hero is a stunning motherboard, with a massive VRM heatsink and active cooling chipset heatsink, dual M.2 slots that support PCIe 4.0, and three full-length PCIe 4.0 slots. With 8 SATA ports, dual M.2 with its own heatsink and cooling region, and 4 DIMM slots for up to 128GB of RAM, there’s plenty of storage. The new WiFi 6 and 2.5 GbE internet are available on this X570 motherboard. The VRM on the Crosshair VIII Hero has been shown to be extremely impressive, with a 14-phase configuration and 60A IR3555 parts, and is only surpassed by the Crosshair VIII Formula, which retails for just under $700.

3.The Best In Budget asus Motherboard For Ryzen 9 3900 X

If you’re building a Ryzen 9 3900X system on a budget, we’re guessing you won’t want to spend a lot of money on the new PCIe 4.0 NVMe SSDs that the new Ryzen 9 3900X and X570 motherboards support.As a result, we suggest using a B450 chipset motherboard for Ryzen 9 3900X builds on a budget, as they provide excellent value for their features, performance, and VRM efficiency.

As a result, we suggest using a B450 chipset motherboard for Ryzen 9 3900X builds on a budget, as they provide excellent value for their features, performance, and VRM efficiency. The B450 Gaming Pro Carbon AC has the best VRM output of any B450 motherboard, as well as a large and impressive feature set for its low price.

4.The Best In Micro ATX Motherboard For the Ryzen 9 3900X

For the Ryzen 9 3900X, there is currently only one X570 micro ATX motherboard available: the ASRock X570M Pro4.

This mATX motherboard has a 10-phase configuration with 8 SATA ports, dual PCIe 4.0 M.2 slots, and dual USB 3.1 Gen 2 ports, including Type C I/O ports.

The only motherboard that will help the Ryzen 9 3900X out of the box is the MSI B450M Mortar, which is widely known as the best micro ATX B450 motherboard on the market in 2019. If you’re willing to do a BIOS upgrade and not use the new PCIe 4.0, we suggest the highly rated MSI B450M Mortar.

5.The Best In Mini ITX Motherboard For Ryzen 9 3900 X Builds

The Gigabyte X570-I AORUS Pro WiFi is the mini-ITX motherboard we like the most, with a good 6-phase VRM with 70A power stages (TDA21472) and plenty of features and networking.

The Gigabyte X570-I AORUS Pro WiFi is said to have better VRM output than the ASRock Phantom ITX and ASUS ROG Strix X570-I Gaming ITX – and we recommend it based on that alone because VRM performance is crucial in an SFF device.

Is Ryzen 9 3900X overkill?

The R9 3900X is overkill for pure gaming, as there isn’t much of a difference in gaming output between Ryzen 5 and Ryzen 9. When it comes to streaming, video encoding, and other tasks, getting the extra cores can be beneficial.This new chip, as powerful as it is, is by no means for everyone. The Ryzen 9 3950X is overkill if you’re purchasing a processor purely for gaming with a single video card, and in 99 percent of situations, a Ryzen 5 3600X or Ryzen 7 3700X would do the job just as well.
