Our Picks

MSI MAG B850 Tomahawk MAX WiFi

Best Value B8501 of 6

MSI MAG B850 Tomahawk MAX WiFi on Amazon (opens in a new tab)

The B850 Tomahawk MAX covers what most Ryzen builds need: four M.2 slots, 5Gbps Ethernet and Wi-Fi 7.

Best for

Most Ryzen gaming builds.

Skip if

If budget leads, the B650M PG Lightning was cheaper at our last price check.

Why we like it

It matches the TUF X870E-PLUS on M.2 slot count (4). It matches the X870 Tomahawk on wired network speed (5Gbps). It also comes with a PCIe 5.0 x16 slot with Steel Armor and a rear USB 20Gbps Type-C port.

It uses AMD's AM5 socket, so it takes Ryzen 7000, 8000 and 9000 chips; a board built before a CPU's launch may need a BIOS update first, so check whether it supports BIOS Flashback. Check the manual for which M.2 slots share lanes with SATA ports or the second PCIe slot before filling them all. When we checked, only the B650 Tomahawk and cheaper picks cost less, and the X870 Tomahawk cost more.

The TUF X870E-PLUS offers four M.2 slots and a 16+2+1 layout of 80A power stages on the X870E chipset.

Best for

Ryzen 9 builds that want the top chipset.

Skip if

Its wired network speed is not published, which rules it out if you need that number.

Why we like it

On M.2 slot count it ties with the B850 Tomahawk MAX at 4. You also get a PCIe 5.0 graphics slot. It uses AMD's AM5 socket, so it takes Ryzen 7000, 8000 and 9000 chips; a board built before a CPU's launch may need a BIOS update first, so check whether it supports BIOS Flashback.

Check the manual for which M.2 slots share lanes with SATA ports or the second PCIe slot before filling them all. It was the highest-priced of the 6 picks at the time of writing, so the case for it rests on what it adds over the X870 Tomahawk and the rest. The maker doesn't give its wired network speed; if that figure matters, the B850 Tomahawk MAX offers 5Gbps.

Key dimensions & specs

  • M.2 slots: 4

Why we like it

It has 5G LAN, an extended VRM heatsink and isolated Audio Boost 5. It matches the B850 Tomahawk MAX on wired network speed (5Gbps). An X870 chipset is unique to it among these picks, while the B650 Tomahawk uses a B650 chipset.

It also offers a PCIe 5.0 M.2 slot and Bluetooth 5.4 alongside Wi-Fi 7. It uses AMD's AM5 socket, so it takes Ryzen 7000, 8000 and 9000 chips; a board built before a CPU's launch may need a BIOS update first, so check whether it supports BIOS Flashback. When we checked, only the B850 Tomahawk MAX and cheaper picks cost less, and the TUF X870E-PLUS cost more. If you want a confirmed M.2 slot count, look to the B850 Tomahawk MAX instead: it offers 4, while this one gives no figure.

How We Chose These AM5 Motherboards

Each pick was assessed across 4 criteria weighted for real-world use.

Storage
We counted listed M.2 slots and PCIe 5.0 support.
Connectivity
We compared Wi-Fi, wired LAN speed and USB4.
Power delivery
We noted power stage layouts where the maker lists them.
Platform
We checked socket, chipset and form factor from each listing.

What to Look for in an AM5 Motherboard

Key buying criteria so you get the right fit the first time.

  1. Match the chipset to your plans

    On AM5, B850 covers most gaming builds with PCIe 5.0 for at least one slot. X870E adds more PCIe 5.0 lanes and USB4 for heavy expansion.

    Features, not frame rates, separate the chipsets.

  2. Count M.2 slots

    Most games now install to NVMe drives. Count how many M.2 slots you need now and later, and check which ones share lanes with other ports.

  3. Power delivery for high-end CPUs

    Boards with more and stronger power stages run hot 16-core chips more comfortably. For eight-core gaming CPUs, most current boards are enough.

  4. Check the rear and front I/O

    Count USB ports you use every day and confirm a front USB-C header if your case has a USB-C port.

  5. Check BIOS support and Flashback

    A board may need a BIOS update before it runs a newer CPU. BIOS Flashback lets you update without a working CPU installed.

  6. Networking matters for daily use

    Wi-Fi 7 and 5Gbps Ethernet help only if your router supports them, but built-in Wi-Fi saves a PCIe card.

Frequently Asked Questions

Is built-in Wi-Fi worth it?

Yes if you cannot run a cable. Otherwise wired Ethernet is more consistent.

Do I need PCIe 5.0?

Current graphics cards barely benefit. PCIe 5.0 matters more for the fastest SSDs.

What size motherboard should I buy?

ATX fits most mid-towers and has the most slots. Micro-ATX and Mini-ITX suit smaller cases with fewer expansion needs.

Will a new board work with my CPU out of the box?

Usually, but check the board's CPU support list. If your chip needs a newer BIOS, BIOS Flashback updates it from a USB drive.

Do I need X870E for gaming?

No. A B850 board runs the same CPUs at the same speed; X870E adds more PCIe 5.0 lanes, USB4 and expansion.

Should I fill all four memory slots?

Two sticks usually run faster and more reliably on DDR5. Buy a two-stick kit with the capacity you need.

Bottom Line

Start with the B850 Tomahawk MAX for most builds. Step up to the TUF X870E-PLUS for a Ryzen 9, or down to the B650M PG Lightning when every dollar counts.
