ASRock B650M PG Lightning WiFi

Also Consider1 of 5

ASRock B650M PG Lightning WiFi on Amazon (opens in a new tab)

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.

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. There is no published M.2 slot count figure, whereas the B850 Pro RS offers 4.

Key dimensions & specs

  • Wired LAN: 2.5Gbps
  • Wi-Fi: Wi-Fi 6E
  • Power stages: 6+2+1
  • Form factor: Micro-ATX
  • Socket: AM5
  • Chipset: B650

Pros

  • BIOS Flashback

Best for

Buyers who want BIOS Flashback.

Skip if

Pass if a published M.2 slot count matters; this one has none.

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. There is no published M.2 slot count figure, whereas the B850 Pro RS offers 4.

Key dimensions & specs

  • Wired LAN: 2.5Gbps
  • Power stages: 14+2+1

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.

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.

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. When we checked, only the TUF B650E-PLUS and cheaper picks cost less, and the TUF B650E-E cost more.

Key dimensions & specs

  • M.2 slots: 4

Best for

Buyers for whom price is not the deciding factor.

Skip if

Worth skipping when wi-Fi 6E rather than Wi-Fi is a problem.

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

Power delivery
We noted power stage layouts where the maker lists them.
Connectivity

What to Look for in a Motherboard for 9800X3D

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. 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.

  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. 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.

  5. 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.

  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

Which of these motherboards has the most M.2 slot count?

The B850 Pro RS leads at 4, ahead of the TUF B650E-PLUS at 3; the TUF B650E-E sits at the other end with 3.

What is the least I can spend on one of these motherboards?

That was the B650M PG Lightning at our last check; if you can stretch, the B850 Pro-A is the next step up and the TUF B650E-E the priciest.

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 PCIe 5.0?

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

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

Our first pick is the B650M PG Lightning, chosen for BIOS Flashback. Look at the B850 Pro-A for BIOS Flashback, the TUF B650E-PLUS for 80A DrMOS power stages and the B850 Pro RS for the most M.2 slot count here (4) if those matter more to you.

Check the board's BIOS version supports the 9800X3D, or pick one with BIOS Flashback.
