Top 10 Best Motherboard For Ryzen 9 3900x – [Complete Buying Guide In 2022]

The Ryzen 9 3900X is AMD’s penultimate 3rd gen Ryzen Processing beast, bettered only by the 16-core/32-thread monster that is Ryzen 9 3950X. The 3900x shines in terms of performance and is also great as a mining CPU.

The best part about it is that if you buy it now, you’re set for quite some time since the performance will only get better once next-gen consoles come out and developers start optimizing games for additional cores and threads.

Does Motherboard Affect Performance?😀

AMD rates the Ryzen 9 3900X at 105 watts. Now, what this means is that you need a world-class board for this processor. The best bit of news is that there are multiple budget models with quality enough VRM that can support this CPU.

Now if you’re thinking about a B450, most of them might be sufficient enough for the 3900X but they usually don’t come accompanied with advanced features.

Don’t forget to ask the seller to Update The BIOS for you in case you go with a B450 or X470 board. Some conventional boards have Flash BIOS feature, allowing users to install new BIOS without hooking up the CPU, but many don’t.

1. MSI B450 Tomahawk Max – Best Compatible Motherboard

You will notice the MSI B450 Tomahawk Max on most lists of the best udget motherboards for Ryzen CPUs. The reason is quite simple. It is a good value for money.

2. MSI X470 Gaming PRO Carbon – Best Cheap Motherboard

The MSI X470 Gaming PRO Carbon is a competitively priced X470 board with a VRM section that was ahead of its time meaning it can host any 3rd gen Ryzen CPU.

You should overclock the 3900X without issues. The board looks pretty attractive. All black design with a couple of grey details and subtle RGB effects on heatsinks.

The alternative to this board is the MSI B450 Gaming Pro Carbon AC. It offers the same package minus the SLI support but it comes with a Wi-Fi module. And its VRM is only a tad weaker.

Best Mini-ITX Motherboard for Ryzen 9 3900X

1. MSI B450I Gaming Plus AC

The MSI B450I Gaming Plus AC is a top-notch option in the Mini-ITX family. Starting, it’s very budget-friendly! Moving on, its VRM is capable enough to run the 3900X at the base clock.

You can even overclock the CPU if you have good enough airflow or a fan directly aimed at the VRM section of the board to allow for sufficient cooling.

Some Important Features That you Need to know:

• DDR4 memory capacity goes up till 3466 MHz.
• Next up, the board has one M.2 slot along with four SATAIII ports.
• You also get one PCIe x16 slot.
• The audio section is a bit weak.
• The Realtek ALC887 Codec is a bit older but it does support 7.1 channel systems.

This is a very decent option for your 3900x, however, if you find the ASUS ROG Strix X570-I Gaming at a better price, we would recommend that one.

Moreover, if you find Gigabyte X570 AORUS Pro WIFI in stock, you should get it if you want to overclock the CPU as it also comes with a 2nd M.2 slot.

2. Gigabyte X570 AORUS XTREME

The Gigabyte X570 Aorus Xtreme is shockingly expensive, but many believe it is the ultimate board for your Ryzen 9 3900x. It is by far one the most feature-packed motherboard to ever sit in our review section.

We could go on and on about the features and capabilities of this board. Extreme overclocking and being the only fan-less X570 motherboard around make this board Godlike! No pun intended.

Anyways, to keep it short, if you have the budget for this monster and are willing to spend that sort of money on a gaming rig, go ahead and stand out from all the other gamers out there. Boards don’t get any better than the Extreme!
