The Ryzen 7 9800X3D fits any AM5 board; B650, B850, X670E and X870 boards all support it after a BIOS update. Every pick is an AM5 board.

We sorted these picks by M.2 slots, wired LAN and wi-Fi, working from the makers' own data; nothing here was tested in-house, and if a maker skips M.2 slots, the guide says so.

Our Picks

Also Consider1 of 5

ASRock B650M PG Lightning WiFi

The B650M PG Lightning is the cheapest route onto AM5 here, a Micro-ATX board with Wi-Fi 6E, 2.5Gbps LAN and BIOS Flashback.

Best for

Buyers who want BIOS Flashback.

Skip if

Choose another pick if you can't accept this: wi-Fi 6E rather than Wi-Fi 7.
ASRock B650M PG Lightning WiFi

Why we like it

Its 6+2+1 layout is best kept to six- and eight-core chips. No other pick in this guide offers 6+2+1 power stages; compare the B850 Pro RS, which has 14+2+1 power stages. You get a B650 chipset here, which sets it apart from the TUF B650E-E and its a B650E chipset.

It also comes with memory support up to DDR5-7200 (OC) and the lowest price among the AM5 boards 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. 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.

Cons

  • Wi-Fi 6E rather than Wi-Fi 7

Strong Alternative2 of 5

ASRock B850 Pro-A

The B850 Pro-A drops Wi-Fi to keep its price low, but keeps a 14+2+1 layout, 2.5Gbps LAN and BIOS Flashback.

Best for

Buyers who want BIOS Flashback.

Skip if

Pass if a published M.2 slot count matters; this one has none.
ASRock B850 Pro-A

Why we like it

It suits desks with a network cable. Like the B850 Pro RS, it has 14+2+1 power stages, while the B650M PG Lightning uses 6+2+1 power stages. You get a B850 chipset here, which sets it apart from the TUF B650E-E and its a B650E chipset.

It also offers memory support to DDR5-8000 (OC) and no Wi-Fi, which keeps the price down for wired setups. 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 a Look3 of 5

ASUS TUF Gaming B650E-PLUS WiFi

The TUF B650E-PLUS uses the B650E chipset, which adds PCIe 5.0 lanes, alongside 80A power stages and BIOS Flashback.

Best for

Buyers who want 80A DrMOS power stages.

Skip if

Look at the others if this bothers you: wi-Fi 6E rather than Wi-Fi 7.
ASUS TUF Gaming B650E-PLUS WiFi

Why we like it

It is a sturdy pick for a 12- or 16-core Ryzen on a budget. It matches the TUF B650E-E on M.2 slot count (3). It is the only pick here with 12+2+1 power stages; the B650M PG Lightning has 6+2+1 power stages instead.

It shares a B650E chipset with the TUF B650E-E; the B850 Pro-A goes with a B850 chipset. 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 B850 Pro-A and cheaper picks cost less, and the B850 Pro RS cost more.

Most M.2 Slots4 of 5

ASRock B850 Pro RS WiFi

The B850 Pro RS keeps four M.2 slots and a 14+2+1 layout on a budget board, with Wi-Fi 6E.

Best for

Buyers who put M.2 slot count first.

Skip if

Skip it if this is a deal-breaker for you: wi-Fi 6E rather than Wi-Fi 7.
ASRock B850 Pro RS WiFi

Why we like it

It leaves more money for the graphics card. On M.2 slot count it leads this guide at 4, ahead of the TUF B650E-PLUS (3). Like the B850 Pro-A, it has 14+2+1 power stages, while the TUF B650E-PLUS uses 12+2+1 power stages.

It also comes with a PCIe 5.0 M.2 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.

Premium Pick5 of 5

ASUS TUF Gaming B650E-E WiFi

The TUF B650E-E pairs a USB 20Gbps Type-C port and BIOS Flashback with three M.2 slots on B650E.

Best for

Buyers for whom price is not the deciding factor, since the B650M PG Lightning costs less.

ASUS TUF Gaming B650E-E WiFi

Why we like it

Its 8+2+1 layout suits mid-range Ryzen chips. On M.2 slot count it ties with the TUF B650E-PLUS at 3. 8+2+1 power stages is unique to it among these picks, while the B850 Pro-A uses 14+2+1 power stages.

Like the TUF B650E-PLUS, it has a B650E chipset, while the B650M PG Lightning uses a B650 chipset. You also get 80A DrMOS power stages. 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 most expensive pick when we checked, so weigh what it adds over the B850 Pro RS.

The catch

If M.2 slot count is your priority, the B850 Pro RS (4) is the stronger choice.

How We Chose

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.

What we compared
We compared five boards on M.2 slot count, wired network speed, wi-Fi and power stages as the makers state them. Nothing was tested in-house; 4 of the 7 fields compared are stated for every pick, while M.2 slot count and wi-Fi have gaps.
The shared baseline
All 5, from the B650M PG Lightning to the TUF B650E-E, state wired network speed, power stages and form factor and share AM5 socket.
Where the specs have gaps
The B650M PG Lightning and the B850 Pro-A give no M.2 slot count; the B850 Pro-A gives no wi-Fi.
Price range
From the B650M PG Lightning to the TUF B650E-E, all sat in the $100 to $150 tier when we checked.

What to Look for in a Motherboard for 9800X3D

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

  1. M.2 slot count across these picks

    Across these 3 picks M.2 slot count spans 3 (the TUF B650E-E) to 4 (the B850 Pro RS). If M.2 slot count is your first filter, the B850 Pro RS sets the ceiling at 4. The B650M PG Lightning and the B850 Pro-A give no M.2 slot count figure, so 3 of 5 picks are compared here.

  2. Features beyond the spec table

    The B850 Pro-A: memory support to DDR5-8000 (OC). The TUF B650E-PLUS: BIOS Flashback. The B850 Pro RS: a PCIe 5.0 M.2 slot.

  3. Budget

    Price does little to separate these 5: the B650M PG Lightning through the TUF B650E-E all landed in the $100 to $150 tier, which leaves M.2 slot count to decide it.

  4. Match the pick to your priority

    Buyers who put M.2 slot count first: the B850 Pro RS. Buyers for whom price is not the deciding factor, since the B650M PG Lightning costs less: the TUF B650E-E.

  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.
