Our Picks

Best Value1 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

Most 7700X builds.

Skip if

Price-first buyers should look at the B650 AORUS Elite AX, which cost less when we checked.
MSI B850 Gaming Plus WiFi

Why we like it

Three M.2 slots cover most gaming builds. Its 5Gbps wired network speed is the fastest here; the TUF B850-PLUS comes next at 2.5Gbps. It shares a B850 chipset with the B850M Steel Legend; the X870 Pro RS goes with an X870 chipset.

It also comes with 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. 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 X870 Pro RS and below the TUF B850-PLUS at the time of writing.

Solid Alternative2 of 6

ASUS TUF Gaming B850-PLUS WiFi

The TUF B850-PLUS offers a 14+2+1 layout of 80A power stages and Wi-Fi 7.

Best for

Buyers who want wi-fi 7 built in.

Skip if

Skip it if price comes first: the B650 AORUS Elite AX cost less when we checked.
ASUS TUF Gaming B850-PLUS WiFi

Why we like it

It suits a 12- or 16-core Ryzen on B850. On wired network speed it ties with the B650 AORUS Elite AX, the B850M Steel Legend and the B650 Steel Legend at 2.5Gbps. It also offers a front USB 10Gbps Type-C header.

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 B850 Gaming Plus and the rest.

Worth Considering3 of 6

GIGABYTE B650 AORUS Elite AX

The B650 AORUS Elite AX pairs a 14+2+1 power layout with a PCIe 5.0 M.2 slot and tool-free EZ-Latch card removal.

Best for

Buyers who want 14+2+1 power stage layout.

Skip if

Worth skipping when wi-Fi 6E rather than Wi-Fi 7 is a problem.
GIGABYTE B650 AORUS Elite AX

Why we like it

It is the most complete B650 board for its price here. It matches the TUF B850-PLUS, the B850M Steel Legend and the B650 Steel Legend on wired network speed (2.5Gbps). Like the B650 Steel Legend, it has a wi-Fi 6E, while the B850 Gaming Plus uses a wi-Fi 7.

It also offers Q-Flash BIOS updating. 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. If you want a confirmed M.2 slot count, look to the B850 Gaming Plus instead: it offers 3, while this one gives no figure.

ASRock X870 Pro RS WiFi

The X870 Pro RS is ASRock's entry X870 board with a 14+2+1 layout, USB4 and Wi-Fi 7.

Best for

USB4 drives and docks.

Skip if

Skip it if you need to know its M.2 slot count before buying; the maker doesn't publish one.
ASRock X870 Pro RS WiFi

Why we like it

It suits builders who want USB4 without paying for extras. An X870 chipset is unique to it among these picks, while the B650 AORUS Elite AX uses a B650 chipset. It also offers memory support to DDR5-8000 (OC) and one of the lowest X870 prices here.

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 B650 Steel Legend and cheaper picks cost less, and the B850 Gaming Plus cost more. If you want a confirmed M.2 slot count, look to the B850 Gaming Plus instead: it offers 3, while this one gives no figure.

Best Micro-ATX5 of 6

ASRock B850M Steel Legend WiFi

The B850M Steel Legend fits a 12+2+1 layout, Wi-Fi 7 and three M.2 slots, one of them PCIe 5.0, onto a Micro-ATX board.

Best for

Compact builds.

Skip if

Look at the others if this bothers you: wired network speed of 2.5Gbps, behind the B850 Gaming Plus (5Gbps).
ASRock B850M Steel Legend WiFi

Why we like it

It is the Micro-ATX pick with the most features here. On wired network speed it ties with the TUF B850-PLUS, the B650 AORUS Elite AX and the B650 Steel Legend at 2.5Gbps. 12+2+1 power stages is unique to it among these picks, while the B650 AORUS Elite AX uses 14+2+1 power stages.

Like the B850 Gaming Plus, it has a B850 chipset, while the B650 Steel Legend uses a B650 chipset. It also offers BIOS Flashback and a white and silver finish. 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 Micro-ATX board it fits smaller cases but has fewer expansion slots than ATX; check the gap between the GPU and the lower slots.

ASRock B650 Steel Legend WiFi

The B650 Steel Legend adds BIOS Flashback to a 14+2+1 layout with Wi-Fi 6E and 2.5Gbps LAN.

Best for

Buyers who want 14+2+1 power stage layout.

Skip if

Skip it if this is a deal-breaker for you: wi-Fi 6E rather than Wi-Fi 7.
ASRock B650 Steel Legend WiFi

Why we like it

Flashback lets you update the BIOS for a newer Ryzen without a working CPU. On wired network speed it ties with the TUF B850-PLUS, the B650 AORUS Elite AX and the B850M Steel Legend at 2.5Gbps. Like the B650 AORUS Elite AX, it has a B650 chipset, while the X870 Pro RS uses an X870 chipset.

It also comes with memory support up to DDR5-7200 (OC) and a white and silver finish. 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. On price it sat third of 6, between the cheaper B850M Steel Legend and the pricier X870 Pro RS, at the time of writing.

How We Chose These Ryzen 7 7700X 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 set side by side six boards on M.2 slot count, wired network speed, wi-Fi and power stages as the makers state them. Nothing was tested in-house; 3 of the 7 fields compared are stated for every pick, while M.2 slot count and wired network speed have gaps.
The shared baseline
All 6, from the B850 Gaming Plus to the B650 Steel Legend, state wi-Fi, form factor and socket and share AM5 socket.
Where the specs have gaps
The B650 AORUS Elite AX, the X870 Pro RS and the B650 Steel Legend give no M.2 slot count; the X870 Pro RS gives no wired network speed.
Price range
At our last check the picks ran from the B650 AORUS Elite AX ($100 to $150) to the TUF B850-PLUS ($150 to $250).
