Some of the Best Motherboard for Ryzen 9 3900x
How to choose a motherboard for Ryzen 9 3900x
One of the most important things you need to consider before building a PC with the new Ryzen processor is a powerful motherboard that utilizes the PCIe 4.0 NVMe SSDs which will provide you with the phenomenal speed of up to 5Gb/s. Apart from that, you would like to have proper airflow in your system which ensures the higher performance of your CPU and for that, I would recommend CPU Coolers.
Next is getting RAM that suits your needs but also is great for your CPU. For the Ryzen 9 3900x we would recommend going for the B-die RAM. A B-die RAM (2x16GB) is when you have 2 Sticks with a Single 8GB IC on it.
Now about those motherboards. For the Ryzen 3000 series including the Ryzen 9 3900x we strongly recommend going for X570. Now the many X470 do support the Ryzen 3000 series and if you already have one or getting one in a sale, then definitely go for it. But if you are purchasing a new board, then don’t leave performance on the table. The X570 chipset is the best when it comes to motherboards for Ryzen 9 3900x.
Now that we know what we need to look for let’s look at some of the premium motherboards that are out there. Note that there could be other boards suitable for Ryzen 9 3900x out there apart from this list. In this list, we have tried to review the ones that are the best motherboard for the Ryzen 9 3900x.
(Editor’s choice) Best X570 motherboard for Ryzen 9 3900x – Gigabyte X570 AORUS EXTREME
Though there are other flagship models from MSI and ASUS, the AUROS EXTREME has set new standards when it comes to AMD flagship motherboards. Looking at what it has to offer, it’s safe to say that cooling and overclocking is what it’s made for.
It comes with a powerful 16 phase VRM, a massive heatsink with a fins-array design, and a Nano Carbon Baseplate. Such a powerful VRM makes CPU cooling extremely important. It doesn’t have an active fan like other X570 motherboards. Instead, they have turned the whole motherboard Into a massive heatsink making it a completely silent X570 board.
Other features that make it a great choice for Ryzen 9 3900x is the use of 3 x PCIe 4.0 full-size lanes, 3xGen4 M.2 slots which support high-speed storage. For networking, it has a 10GbE inbuilt LAN and Wi-Fi 6 standard. Apart from this, you get many USB and SATA connectivity slots, ESS sabre HiFi as their audio solution, and dual BIOS and socketed BIOS chips.
If you just want the best of the best then this is your choice of board.
Best Overall Motherboard for Ryzen 9 3900x – ASUS Crosshair VIII Hero Wi-Fi
The Crosshair VIII Hero Wi-Fi is an ATX offering from ASUS in the X570 chipset motherboards. Currently, ASUS offers only ATX form factor boards in the X570 chipset range. If you are looking for ITX boards then you should consider going for Gigabyte or ASRock that we will discuss a bit later. Now the Crosshair VIII sits at the upper mid-range of price in X570 boards.
This is a beast when it comes to connectivity options. With 12 USB ports, which includes 8 USB 3.2 Gen 2 (1 Type C and 7 Type A), inbuilt LAN 2.5G Realtek, and an integrated Intel Wi-Fi 6. Apart from this, you get 8 SATA ports and 4 DIMM which can support a whopping 128 GB of DDR4 RAM.
Now one of the most important aspects of a motherboard – VRM. The Ryzen 9 3900x compatible motherboard has a 14 phase (12+2) VRM. Now when it comes to most flagship X570 motherboards they have by and large the same in terms of VRM quality. So you can’t go wrong with that.
Now what makes this mobo for Ryzen 9 3900x a preferred choice is its most convenient BIOS tweak for 3900x CPU.
Apart from the gigantic VRM and active cooling heatsink, this AMD motherboard comes with 2 M.2 slots, 3 PCIe 4.0 slots, and plenty of storage space. A great choice for Ryzen 9 3900x. As it audio solution, it uses the ROG SupremeFX codec which is actually a bit tweaked Realtek ALC 1220. This is in fact one of the most premium audio solutions out there.
Best Budget motherboard for Ryzen 9 3900x – ASUS Prime X570-P
If you are on a budget but still want the benefit of an X570 chipset then the ASUS Prime X570 motherboard is what you should be looking for. One thing I love about this is that you get all the features you would ever need even on an entry-level board. Along with that, you get the AM4 socket which makes it quite suitable for pairing with Ryzen 3000 series chipsets as an entry-level board.
You would get a 12+2 phase solid VRM that’s just the same quality as any other X570 board out there. When it comes to RAM capacity you can fit 4 x32GB 4400MHz DDR4 RAM with a maximum of up to 128GB. It makes good use of PCIe 4.0 standard with two full-length PCIe 4.0 slots and dual PCIe 4.0 M.2 slots. You can easily run PCIe 4.0 x 4 drives but if you are looking to get NVMe drives then I’m afraid you’d have to get your own heatsink. As these can get quite heated due to high speeds.
After this let’s look at the USB ports, you get four USB 3.1 G2 Type-A, two USB 3.1 G2 Type-A, and two USB 2.0 ports but sadly no Type C USB port. This is alright in regards to its low cost. As its an audio solution it features a Realtek S1200A HD audio codec.
In terms of the graphics card, this model can support two-way AMD Crossfire configuration but no support for NVIDIA SLI.
It’s the budget offering from ASUS in the ATX form factor build and is a great option for Ryzen 9 3900x.
Best Micro ATX motherboard for Ryzen 9 3900x – ASRock X570M Pro4
When it comes to Micro ATX boards they lie in the middle ground. They are able to handle more devices and even have a better power delivery than a Mini ITX board. Also, they take only a fraction of space as compared to a full-sized ATX board.
ASROCK’s X570 Pro4 is currently one of the only handful of Micro ATX boards available in the market. With Micro ATX boards you can expect a smaller number of PCIe ports but there is definitely no reduction in quality.
This board features 8 SATA slots and uses PCIe standard with dual PCIe M.2 slots and also one M.2 heatsink. Now if we check the VRM we get a 10 phase VRM which is sure to produce some significant heat. The heatsink though doesn’t seem to have enough surface area to handle it properly. A 40nm fan is also placed in the center which doesn’t seem to have much effect. All in all, you could face some heating issues in case of extensive usage.
The ASRock X570M definitely has some issues. If your main concerns are space and cost in a motherboard. Then you can get similar power as that of a full-sized ATX board in this pick. It’s not only compact but also in the budget end of the X570 boards.
Best Mini ITX motherboard for Ryzen 9 3900x – Gigabyte X570-I AORUS Pro Wi-Fi
Now let’s look at the Mini ITX range of boards. People go for a Mini ITX when they want a smaller form factor build. This could be to gift someone or just to avoid the overall hassle of setting up a full-sized PC. A smaller form factor build such as a Mini-ITX build lets you connect some great hardware along with it. Now if you want to connect your Mini ITX board with a heavy graphic card then what you need is the advanced chipset.
This is where the X570-I AORUS Pro Wi-Fi comes into play. Currently, it’s the only Mini ITX offering in the market that is worth anything. The high-end chipset lets you use PCIe 4.0 and a higher range of memory. But then it’s the price. It priced almost around the price you’d get a full-sized ATX board in the market. Now if it has the price it also has the value to back it up.
An 8 phase solid VRM with 2 M.2 slots supporting PCIe 4.0 x 4 drives. Now, this is not so common in many Mini ITX boards. For networking, you get Gigabit Ethernet and inbuilt Wi-Fi 6. Now a 6+2 VRM can get quite heated in a small board like this. To tackle this you get a heatsink that covers the whole rear panel cover. The large surface area of the heatsink ensures that most heat gets dissipates and doesn’t cause any performance issues.
When you get to RAM this board can support up to 64GB of DDR4 4400MHz of RAM. In a Mini-ITX board in terms of performance, this is the best motherboard you can get. For a competitive board with small size but performance on par with full-sized ATX boards, the Gigabyte X570-I is your choice of board.
