MSI MAG B850 Tomahawk MAX WiFi

Lowest Price Here1 of 5

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 on a reinforced PCIe 5.0 graphics slot.

Best for

Buyers who would rather put the savings elsewhere in the build.

Skip if

Look at the other picks if you need a feature not covered above.

Why we like it

It is the board to start from unless you need something specific. On M.2 slot count it ties with the Z890 Tomahawk II and the Strix Z890-H at 4. It shares an AM5 socket with the X870 Tomahawk and B850I Edge TI; the Strix Z890-H goes with an LGA1851 socket.

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. It undercut the X870 Tomahawk and every other pick on price at the time of writing.

MSI MPG B850I Edge TI WiFi

Premium Pick5 of 5

MSI MPG B850I Edge TI WiFi on Amazon (opens in a new tab)

The B850I Edge TI is the only board here with 5Gbps Ethernet, alongside Wi-Fi 7 and two M.2 slots.

Best for

Buyers for whom price is not the deciding factor.

Skip if

Worth skipping when only 2 M.2 slot is a problem.

Why we like it

Its white finish suits light-themed small builds. On M.2 slot count it trails the group at 2, while the B850 Tomahawk MAX offers 4. It shares an AM5 socket with the B850 Tomahawk MAX and X870 Tomahawk; the Strix Z890-H goes with an LGA1851 socket.

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. As a Mini-ITX board it has one PCIe x16 slot and two memory slots, so plan for a two-stick memory kit and check the case's cooler and GPU limits. It was the highest-priced of the 5 picks at the time of writing, so the case for it rests on what it adds over the Strix Z890-H and the rest.

How We Chose These Motherboards Under $300

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

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

What to Look for in a Motherboard Under $300

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

  1. 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.

  2. 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.

  3. 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.

  4. 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.

  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. 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.
