1. MSI X570 Tomahawk: Best value X570 motherboard for Ryzen 9 5900X
While we don’t recommend getting a budget X570 board for the 5900X, the mid-range market has plenty of great choices. Our recommendation for the best value X570 motherboard for the Ryzen 9 5900X goes to the MSI X570 Tomahawk. This is an amazing board with the superb build quality and high-end VRM.
You get support for fast memory, up to DDR4 4600 MT/s, six SATA III ports, and two M.2 slots. When it comes to expansions slots, you have two PCIe x16 slots accompanied by two PCIe x1 ports. When it comes to audio, The X570 Tomahawk features the Realtek ALC 1200 codec, which is a solid mid-range choice.
As for the connectivity options, you get 2.5Gb LAN on the MSI X570 Tomahawk. This is a pretty good deal since most budget and even mid-range X570 motherboards come with 1Gbps LAN chips.
The MSI Tomahawk comes with four USB 3.2 Gen 2 ports (one of which is USB-C), two USB 3.2 Gen 1 ports, two USB 2.0 ports, and a BIOS Flashback button. Not the most richly equipped rear I/O on the market but packed enough for most users.
2. MSI B550-A Pro: Best value B550 motherboard for Ryzen 9 5900X
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 B550 motherboard for the 5900X 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 MT/s; 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. Overall, the B550-A Pro is a B550 motherboard with fantastic value. The only downside we can think of is the barebones audio setup.
3. Gigabyte B550 Vision D: Best high-end B550 motherboard for Ryzen 9 5900X
If you need even more features, the high-end market has lots of excellent choices. Do note that the B550 models listed here are more affordable than the high-end X570 boards.

Ryzen 9 5900X motherboard compatibility
AMD made sure that Zen 3 CPUs can be installed on a wide range of AM4-compatible motherboards. For starters, 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 to get 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, you shouldn’t combine an A520 model with the 5900X.
While some A520 boards should run the 5900X without issues, you shouldn’t risk it. If you’re looking for a budget motherboard compatible with the 5900X, get a cheap B550 model.
