The new Zen 3 CPU Lineup is hit the shelves with the Ryzen 9 5900X being arguably the best buy of the four CPUs offered at the launch. 12 very fast cores with hyperthreading and single-core performance that’s ahead of Intel’s best gaming CPU should make the Ryzen 9 5900X the best choice for both gamers and professionals. It has almost the same power requirements as its predecessor, the Ryzen 9 3900X, so it’s safe to say that all boards that are capable of running the 3900X will work fine with the 5900X.
All of you who plan on getting the 5900X are probably looking for the best motherboard to pair with your next CPU. Well, here you’ll find the best B550 and X570 boards for the 5900X. Motherboard models with B550 and X570 chipsets should receive a BIOS update that will make them compatible with Zen 3 CPUs on day one. Now, while we didn’t include B450 boards on this list, some of them should work fine with the 5900X.
The thing is, B450 boards should receive their Zen 3 compatibility update sometime in January 2021. If you want the get the 5900X on launch day, November 5, you have to either buy a B550 or X570 board. If you already have a high-quality B450 board such as the MSI B450 Tomahawk Max our advice is to wait for the January BIOS update and then get a Zen 3 CPU.
There’s no need on getting a new board unless you need PCIe 4.0 or want to get the 5900X on launch day. Finally, while A520 motherboards are technically compatible with Zen 3 we didn’t include them since the A520 is a budget chipset made for APUs and lower-tier CPUs. So, without further ado, let’s check out the best motherboards for the Ryzen 9 5900X.

Best B550 Motherboard For Most Ryzen 9 5900X Owners
When it comes to B550 motherboards, the situation is pretty similar to the one we have on the X570 market. The cheapest boards won’t work with the 5900X so you have to pay a bit extra for a motherboard that can run the CPU. The best budget choice is the MSI B550-A Pro. This one’s only a bit more expensive than the cheapest B550 options while coming with decent specs and VRM good enough to run an overclocked 5900X without issues.
It can run DDR4 memory up to 4400, it has two M.2 slots and six SATA III ports, dual PCIe x16 slots, and two PCIe x1 slots. Remember that B550 boards do come with PCIe 4.0 support, but only the primary PCIe x16 slot and the primary M.2 slot are PCIe 4.0 compatible. In case a B550 motherboard has more than one PCIe x16 and M.2 slot, secondary slots are only PCIe 3.0 compliant.
As for the audio section, it’s powered by the Realtek ALC892 audio codec, which is a pretty basic setup nowadays. Connectivity options include only gigabit LAN. As for the rear I/O, you’ll find two USB 3.2 gen2 ports (one of which is USB-C), two USB 3.2 gen1 ports, as well as four USB 2.0 ports. Interestingly enough, the rear I/O also includes a flash BIOS button, which is a welcome extra at this price point.

Best mATX Motherboard For Ryzen 9 5900X
The X570 mATX offering is pretty slim, consisting of poor-quality boards so if you’re looking for a micro ATX board to pair with the 5900X your choices are limited to B550 boards. The best budget choice here is the MSI B550M Mortar. It’s a tightly packed board that supports 4400MHz DDR4 memory, comes with two M.2 slots and six SATA III ports, and features two PCIe x16 and two PCIe x1 ports.
The Realtek ALC1200 codec is responsible for audio, which is a solid solution and when it comes to connectivity you have one 2.5Gb LAN port. The rear I/O hosts two USB 3.2 gen2 ports (one is USB-C), two USB 3.2 gen1 ports, and two USB 2.0 ports. The ASUS TUF B550M-Plus is very similar in specs while having just a bit weaker VRM. Also, both boards are available in Wi-Fi variants. The B550M TUF is as good a buy as the B550 Mortar. The final choice between the two should come down to availability and design, not raw specs comparison.
If you need something even cheaper that works fine with the 5900X check out the MSI B550 Bazooka and the ASRock B550M Steel Legend. They both have weaker VRMs, but capable of dealing with an overclocked 5900X. On the flipside, expect fewer connectivity options and higher working temps.

Best Mini-ITX Motherboard For Ryzen 9 5900X
Finally, we’ve arrived to the best Mini-ITX board for the Ryzen 9 3900X and that award goes to the ASUS ROG Strix X570-I Gaming. This is a beast in a small form factor that has one of the best VRMs seen on a Mini-ITX motherboard. On top of that, you get support for DDR4 4800, two M.2 slots, and four SATA III Ports. The board has a single PCIe x16 port and it comes with a pretty solid audio section powered by the S1220A audio codec. On the back end, you can find four USB 3.2 gen2 (one is USB-C), four USB 3.2 gen1 ports, and the usual selection of audio jacks. As for the connectivity, this board features gigabit LAN, Wi-Fi 6, and Bluetooth 5.
When it comes to B550 mini-ITX boards, they all seem decent to run the 5900X at least at stock clock. They differ in VRM and cooling solutions so if you want the best the MSI B550I Gaming Edge or the ASUS ROG Strix B550-I Gaming look like the best choices.
