Best AM5 Motherboards of 2026

Four M.2 slots, two of them PCIe 5.0. That's the number that makes the Tomahawk MAX the interesting board in this group, because most of the B850 competition stops at three slots and one fast lane. If you keep a boot drive, a game library and a scratch disk for editing all mounted at once, this is the board that doesn't make you choose between them.

The extras it adds are narrow enough that it lands behind the top pick overall, but for a storage-heavy or network-heavy build it wins outright. Five-gigabit Ethernet is the fastest wired connection on any board here, Wi-Fi 7 covers the wireless side, and the PCIe 5.0 x16 slot is reinforced for a heavy graphics card. The 14 duet-rail 80A stages are in the same league as the Gigabyte's, and the four DIMM slots take DDR5 rated to 8400+ MT/s with one stick per channel.

Where it gives ground is coverage: three years against Gigabyte's five, on a board that costs about the same. Otherwise the decision between the two comes down to what you'll plug in — four drives and a 5-gigabit line, or a slightly easier BIOS and two extra years of warranty. Six SATA ports also make it the friendlier home for a stack of old hard drives.

Small cases and light-colored builds usually force a compromise, and this is the board that doesn't. It's a 9.6-inch micro-ATX square with a white finish and grey accents, so a white case doesn't end up with one black rectangle in the middle of it, and it keeps four DIMM slots, a PCIe 5.0 M.2 slot, 2.5-gigabit Ethernet and a front USB-C header.

What it gives up is width and a little future-proofing: two M.2 slots instead of three or four, Wi-Fi 6E rather than Wi-Fi 7, and 12+2+2 power stages instead of 14. In a compact build none of that bites. Two drives covers most gaming setups, 6E is fine on any router you already own, and 12+2+2 phases will feed a 9800X3D without breaking a sweat. The 2.5-gigabit Ethernet is the same speed as the full-size picks.

The finish is a step up from Gigabyte's entry boards — encased heatsinks rather than bare fins, and an integrated rear I/O cover that cleans up the back of the case. Our one practical annoyance: there's no printed layout diagram in the box, so download the PDF before you start plugging headers in. The front-panel pinout is the part you'll actually need.

It's the most expensive board here by a wide margin, and ASUS spends the difference on things you can point at: 18+2+2 stages rated at 110A each, five M.2 slots, USB4, six SATA ports and a reinforced PCIe 5.0 x16 slot with a release you trip by pulling the card rather than hunting for a latch behind it. Build quality is the other thing you notice — the heatsinks are heavy, and the board feels like the foundation for a machine you keep for five years.

What makes it worth the money is headroom rather than the spec count. Dynamic OC Switcher, Core Flex and PBO Enhancement are dials the B850 boards don't offer, and the power delivery has enough margin that a 16-core chip at full load isn't where you compromise. Then there's USB4, the one feature that makes an external dock or a fast external SSD feel native instead of adapted. If the build itself is the hobby, this is the board that keeps rewarding it.

Two things to weigh first. The price puts it in a different bracket from everything else here, and high-speed memory is where to be careful: check the QVL for the kit you plan to buy, because this is a board where validated modules save an evening of troubleshooting. Buy it for USB4, for five drives, or for a chip you intend to tune. Otherwise the B850 picks do the same job for a lot less.

This is the board we point at when someone wants a full-size AM5 build and doesn't want to pay B850 money. It's a generation behind the newer chipsets, but the parts that matter survived the downgrade: three M.2 slots with heatsinks on all of them, one of those running PCIe 5.0, plus 2.5-gigabit Ethernet, Wi-Fi 6E, four SATA ports and 12+2 power stages fed by 8+4-pin ProCool connectors.

Preparation is the catch. Wi-Fi and Bluetooth drivers aren't waiting in a fresh Windows install — they live on ASUS's support page — so put them on a USB stick from another machine before you build, or you'll be chasing a connection you can't get online to fix. Do the same for the chipset and audio drivers while you're there. It's a five-minute job that saves an evening, and it's the only real friction we hit with this board.

Set that up in advance and it's easy to live with. Three M.2 slots means storage doesn't need a plan, 2.5-gigabit Ethernet matches the mid-range picks, and the money you save is better spent on a graphics card, which is where the frames actually come from. For a first build or a second machine where the newest chipset isn't the point, this is the sensible one.
