  • $208.98
  • 4.3 (1,679 reviews)
  • Pros Mini-ITX size, the smallest here
  • Cons Two memory slots, per the listing, against four on the other picks

Prices and ratings as of October 5, 2026.

Pros and cons

Why it made the list

  • It is the only mini-ITX board here, and its listing still names one PCIe 4.0 x16 slot, a PCIe 4.0 M.2 slot and a PCIe 3.0 M.2 slot.
  • The listing names an extended VRM heatsink, an aluminium backplate and an integrated rear-port shield.
  • It lists USB 3.2 Gen 2 Type-C and Type-A ports plus four USB 3.2 Gen 1 Type-A ports.

Drawbacks

  • Its listing gives two memory slots, against four on every other pick.
  • PC Guide says mini-ITX boards leave little room to upgrade.

Watch for this: Amazon’s data groups this board with the Gigabyte B550 AORUS Elite AX V2 and the B550M AORUS Elite AX. They are different boards, so match the model name in the title.

Skip it if your case takes a larger board or you want four memory slots.

Top AlternativeBest A520 board for a lower-cost build
ASUS TUF Gaming A520M-PLUS WiFi

ASUS TUF Gaming A520M-PLUS WiFi

Best for: A micro-ATX A520 board for a lower-cost build

  • $99.99
  • 4.6 (1,385 reviews)
  • ★ Amazon's Choice
  • Pros A520 board whose listing names Ryzen 5000, 4000 G-series and 3000 support
  • Cons Its M.2 slot is listed at 32Gb/s, where the B550 picks list PCIe 4.0

Prices and ratings as of October 5, 2026.

Pros and cons

Why it made the list

  • The listing names Ryzen 5000 series, 4000 G-series and 3000 series support on an A520 board.
  • It lists 802.11ac Wi-Fi and a BIOS FlashBack button, with DisplayPort, HDMI and D-Sub outputs.
  • It names a large VRM heatsink, a chipset heatsink and Fan Xpert 2+.

Drawbacks

  • Its M.2 slot is listed at 32Gb/s, where the B550 picks list PCIe 4.0.
  • Its 802.11ac Wi-Fi is older than the Wi-Fi 6 on the other picks.
  • The micro-ATX size also limits it to fewer slots than ATX.

Watch for this: The detail table’s chipset field reads “AMD 785E” while its title and family field say A520. The title and family field agree with the model name, so we treat it as an A520 board.

Skip it if you want PCIe 4.0 storage or the newer Wi-Fi of the B550 boards.

How to choose an AM4 motherboard

For this guide, an AM4 motherboard is a board with a Socket AM4 processor socket and DDR4 memory, and a board counts only when its own listing says so. Boards for the newer AM5 socket also show up in Amazon’s AM4 results, which is why two of them were set aside below.

Chipset. Budget Loadout calls B450 the value-first route, B550 the balanced option for most serious gaming builds, and X570 a choice for buyers who know exactly why they need the extra platform features. PC Guide agrees that B550 is the better buy for most gamers, with PCIe 4.0 support and strong power delivery, and says X570 is worth considering for more PCIe lanes or enthusiast-level features. Five of our six picks are B550 boards and one is A520.

Processor support. Budget Loadout warns against buying on the chipset label alone: check the exact board model, its processor support list and whether it ships with a BIOS that supports your chip, because two AM4 boards can share a socket and still differ on support out of the box. Each pick below names only the processor generations its own listing names. None of them is described here as working with every Ryzen chip.

Size. Tom’s Hardware lists the three main sizes as ATX, Micro ATX and Mini-ITX, and says smaller boards mean fewer card slots, often fewer RAM slots and generally fewer features. PC Guide says a mini-ITX board leaves little room to upgrade. We kept two ATX boards, three micro-ATX boards and one mini-ITX board.

Memory. Tom’s Hardware says AM4 boards use the older and more affordable DDR4 memory, which can cut a build’s cost, especially if you already own a DDR4 kit. The detail tables of all six boards give DDR4.

Wi-Fi and extras. Tom’s Hardware advises paying for built-in Wi-Fi and high-end ports only if you need them. Every board here has Wi-Fi in its listing, so if you plan a wired build, a board without it may fit you better than any pick below.

What we left out, and why

We read 44 search cards, found 37 different listings and compared the product details of 10 boards. Here is which part each of the four boards we dropped fails.

  • MSI B550M PRO-VDH WiFi. It sits in the same variant family as the MSI PRO B550M-VC WiFi and a third listing, which are different models, so we could not show that its reviews describe only this board, so it is not a pick.
  • MSI MPG X570 Gaming Plus. In the listing text we read it names 2nd and 3rd Gen Ryzen support and not the 5000 series, and the offer shown looked unlike a normal new offer, so we could not confirm one.
  • MSI B450 Gaming Plus Max. An older B450 board whose listing names 1st to 3rd Gen Ryzen support, with the same doubt about its offer.
  • Gigabyte B550 AORUS Elite AX V2. A full-size B550 board that the first two picks already cover, from the same Gigabyte variant family as the Gigabyte B550I AORUS PRO AX.

Two AM5 boards, the ASUS ROG Strix B850-A Gaming WiFi and the Gigabyte B650 AORUS Elite AX, appeared in the AM4 results and were removed, along with a processor-and-board bundle and a Wi-Fi antenna. Wirecutter has no page for this keyword in Google’s top 10, so there is no outside pick in the table.

How we researched

On October 5, 2026 we read the 44 Amazon search cards Chrome rendered for “am4 motherboard” over two results pages, 37 different listings. AI compared them, set aside AM5 boards, a processor bundle, an antenna and sponsored repeats, and chose 10 boards whose product details were read through a data provider rather than in a browser. Six met this guide's definition and each suit a different build. AI wrote this guide from that research.

Listings change: we read them on October 5, 2026, and a seller, revision or stock may differ today. The product details came through a data provider, so a listing's own bullets and detail table are the source for every spec, and a few review headlines were read only to check for mixed-up listings. Processor support is only what each listing says; confirm your exact chip on the maker's support page.

Prices, ratings and review counts come from Amazon and were read on October 5, 2026.

Frequently asked questions

Is AM4 still worth buying?

PC Guide says yes: AM5 offers the latest Ryzen processors and DDR5 memory, but AM4 remains an excellent value platform, and a Ryzen 5000 processor on a quality B550 or X570 board still gives strong gaming performance at a low build cost. It also says AM4 leaves no future-upgrade room.

Is a B550 or an X570 board the better buy?

PC Guide recommends B550 for most gamers because it offers PCIe 4.0, strong power delivery and modern connectivity, and keeps X570 for people who need more PCIe lanes, more expansion or enthusiast-level features. Budget Loadout reaches the same view and says many gaming builds will not use what separates X570 from a solid B550 board.

Will an AM4 board work with my Ryzen chip?

Not automatically. Budget Loadout says to match the board to the exact Ryzen generation, confirm out-of-box BIOS support with the seller or maker, and be careful with vague phrases such as “supports AM4 CPUs”. Each pick above gives the support its own listing states.

Does the motherboard need built-in Wi-Fi?

Only if you use wireless. Tom’s Hardware says to pay for built-in Wi-Fi and high-end ports only if you need them. All six boards here list Wi-Fi. Building the rest of the PC? See our guide to CPU air coolers.
