Our Picks
Best All-Round1 of 6
MSI MAG B850 Tomahawk MAX WiFi
The B850 Tomahawk MAX covers what most Ryzen builds need: four M.2 slots, 5Gbps Ethernet and Wi-Fi 7.
Best for
- Most 7800X3D builds.
Skip if
- Price-first buyers should look at the B650 Tomahawk, which cost less when we checked.
Why we like it
It matches the Strix B850-A on M.2 slot count (4). It matches the X870 Tomahawk and the B850 Gaming Plus on wired network speed (5Gbps). It also offers 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 was priced above the Strix B850-A and below the X870 Tomahawk at the time of writing.

ASUS ROG Strix B850-A Gaming WiFi
The Strix B850-A offers four M.2 slots, a 14+2+2 layout, Wi-Fi 7 and a white finish.
Best for
- Buyers who want 4 m.2 slots for ssd expansion.
Skip if
- Skip it if price comes first: the B650 Tomahawk cost less when we checked.
Why we like it
Its 14+2+2 VRM is rated at 80A per stage, and heatsinks bridge to the VRMs with thermal pads. ASUS AI Advisor simplifies setup. It matches the B850 Tomahawk MAX on M.2 slot count (4).
It matches the B650 Tomahawk and the Strix B850-I on wired network speed (2.5Gbps). It also comes with a rear USB 20Gbps 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.

Worth Considering3 of 6
MSI MAG X870 Tomahawk WiFi
The X870 Tomahawk pairs 5Gbps Ethernet with Wi-Fi 7 and USB4, covering the connectivity most builders want for years.
Best for
- Buyers who want 5gbps wired ethernet.
Skip if
- Pass if a published M.2 slot count matters; this one has none.
Why we like it
It has 5G LAN, an extended VRM heatsink and isolated Audio Boost 5. It matches the B850 Tomahawk MAX and the B850 Gaming Plus on wired network speed (5Gbps). You get an X870 chipset here, which sets it apart from the B850 Gaming Plus and its a B850 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. It was priced above the B850 Tomahawk MAX and below the Strix B850-I at the time of writing.

Best Budget4 of 6
MSI MAG B650 Tomahawk WiFi
The B650 Tomahawk is the steady middle of the B650 range: Wi-Fi 6E, 2.5Gbps Ethernet and display outputs on an ATX board.
Best for
- Spending more on the GPU.
Skip if
- Look at the others if this bothers you: wi-Fi 6E rather than Wi-Fi 7.
Why we like it
It has no PCIe 5.0 graphics slot, which matters little for today's cards. It matches the Strix B850-A and the Strix B850-I on wired network speed (2.5Gbps). No other pick in this guide offers a wi-Fi 6E; compare the B850 Gaming Plus, which has a wi-Fi 7.
You get a B650 chipset here, which sets it apart from the B850 Gaming Plus and its a B850 chipset. It also offers Lightning M.2 support, Bluetooth 5.3 alongside Wi-Fi 6E and HDMI and DisplayPort outputs for Ryzen chips with graphics. 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. It cost the least of the 6 picks at the time of writing, with the B850 Gaming Plus the next step up.

Best Mini-ITX5 of 6
ASUS ROG Strix B850-I Gaming WiFi
The Strix B850-I fits Wi-Fi 7, 2.5Gbps LAN and a 10+2+1 layout onto a Mini-ITX board for small builds.
Best for
- Small-form-factor gaming PCs.
Skip if
- Skip it if this is a deal-breaker for you: only 2 M.2 slots.
Why we like it
On M.2 slot count it trails the group at 2, while the B850 Tomahawk MAX offers 4. On wired network speed it ties with the Strix B850-A and the B650 Tomahawk at 2.5Gbps. You also get a rear USB 20Gbps port and 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. 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 most expensive pick when we checked, so weigh what it adds over the X870 Tomahawk.

Well-Rounded Choice6 of 6
MSI B850 Gaming Plus WiFi
The B850 Gaming Plus WiFi brings 5Gbps Ethernet and Wi-Fi 7 to an entry-level B850 price, with a PCIe 5.0 M.2 slot.
Best for
- Buyers who want 5gbps wired ethernet.
Skip if
- Price-first buyers should look at the B650 Tomahawk, which cost less when we checked.
Why we like it
Three M.2 slots cover most gaming builds. Its 3 M.2 slot count ranks third of 4 here, behind the B850 Tomahawk MAX (4) and ahead of the Strix B850-I (2). It matches the B850 Tomahawk MAX and the X870 Tomahawk on wired network speed (5Gbps).
You get a B850 chipset here, which sets it apart from the B650 Tomahawk and its a B650 chipset. You also get memory support to DDR5-8200 (OC). 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.

How We Chose These Ryzen 7 7800X3D Motherboards
Alex Morgan compared the manufacturer specifications, connectivity, warranty terms and compatibility of every pick. Figures come from the makers unless a third-party source is named; we did not test these products ourselves.
- How these picks were ranked
- We lined up six boards on M.2 slot count, wired network speed, wi-Fi and power stages from manufacturer specifications. We did not test them in-house, and M.2 slot count and power stages are missing for at least one pick.
- The shared baseline
- All 6, from the B850 Tomahawk MAX to the B850 Gaming Plus, state wired network speed, wi-Fi and form factor and share AM5 socket.
- Where the specs have gaps
- The X870 Tomahawk and the B650 Tomahawk give no M.2 slot count; the B850 Tomahawk MAX, the X870 Tomahawk, the B650 Tomahawk and the B850 Gaming Plus give no power stages.
- Price range
- At our last check the picks ran from the B650 Tomahawk ($150 to $250) to the Strix B850-I ($250 to $500).
What to Look for in a Ryzen 7 7800X3D Motherboard
Key buying criteria so you get the right fit the first time.
How much wired network speed you need
The B850 Tomahawk MAX tops wired network speed at 5Gbps and the Strix B850-I sits lowest at 2.5Gbps; 3 picks share the top figure. The B850 Tomahawk MAX is the pick for wired network speed.
M.2 slot count across these picks
Across these 4 picks M.2 slot count spans 2 (the Strix B850-I) to 4 (the B850 Tomahawk MAX). The Strix B850-A comes second at 4, in the same price tier as the B850 Tomahawk MAX. The X870 Tomahawk and the B650 Tomahawk give no M.2 slot count figure, so 4 of 6 picks are compared here.
Power stages
The Strix B850-A lists 14+2+2; the Strix B850-I lists 10+2+1. Sort out power stages before price: it splits 2 stated picks into groups of 1 and 1.
