Best X670E Motherboards of 2026

The Carrara is the only board here that changes what the inside of a case looks like. The white, marble-patterned finish runs across the heatsinks and the I/O shroud, and it holds up close rather than reading as a printed decal. This is a board people leave the side panel off for.

Under the finish it's the most connected board in the group by a wide margin: two PCIe 5.0 x16 slots, eight SATA ports, two Ethernet ports and fifteen USB ports, plus a vertical M.2 mount that stands a drive up off the board instead of laying it flat. If you're carrying a stack of 2.5-inch drives over from an older build, those eight SATA ports are the reason to look here at all — nobody else in this set gets past six.

We like it as a statement build rather than a value play. The shroud, the port count and the second full-length Gen5 slot are what you're paying for, and none of them are subtle. The finish is a commitment too: pair a marble-white board with blacked-out components and you've bought a look you're covering up.

One thing to check before ordering: the vertical M.2 mount holds a drive above the board, so give it room against a tall air cooler or a thick top radiator.

Two white boards in one roundup only makes sense if they do different jobs, and these two do. The ROG Strix X670E-A keeps the pale heatsinks and silver accents but stays a conventional ATX board: four M.2 slots all under heatsinks, 16+2 power stages on an 8+8 feed, and PCIe 5.0 for the graphics card. Of the pair, this is the one we reach for when the goal is a fast, quiet machine that also happens to look right.

Installation was the least eventful part of our time with it. The M.2 latches are tool-free, the four heatsinks are already fitted, and the BIOS groups memory and fan settings where a first-time builder will find them. The board also took a moderate EXPO kit without argument, which is the step in an AM5 build most likely to eat an evening.

The soft spot is wired networking. The board's Intel I226-V controller can drop a link or refuse to negotiate, and a PCIe network card settles it permanently for very little money. Everything else about the board stays worth it — against the Tomahawk you gain power stages, and against the Carrara you give up SATA ports and marble and keep the four cooled M.2 slots.

The TUF board is the least exciting thing in this roundup, and that's the point. No mirrored plates, no light show — an eight-layer PCB, 8+8 ProCool CPU sockets, and a matte heatsink stack that disappears once a graphics card goes in. What it does carry is a Thunderbolt (USB4) header, which is how you add a fast external drive array or a dock without spending a slot on it.

What surprised us was how complete the rest of it looks for a board this unglamorous: four M.2 slots, 2.5Gb Ethernet, Wi-Fi 6E, a front USB 3.2 Gen 2 Type-C header, and TUF's LANGuard protection on the network port. The power design is a step below the ROG boards here, which matters if you're chasing an all-core overclock on a 16-core chip and doesn't if you're running a Ryzen 7 the way most gamers do.

The behavior to plan around is boot. After a memory change this board can sit in its RAM check or drop into BIOS safe mode before it eventually posts, which reads like a dead board and usually isn't. Change one thing at a time — memory first, EXPO second — and give it a few minutes before you start reseating anything. Nothing here is going to impress anyone looking into your case, and it's going to be the part you never think about again.

Look at the slot stack before you fall for the rest of it. Two of the Carbon's M.2 positions sit above the primary PCIe 5.0 x16 slot, which pushes a graphics card down toward the floor of the case. In a full tower with clear space underneath that's nothing; above a bottom-mounted radiator, or with a four-slot card, it's the whole build.

If you have the room, the payoff is real: two PCIe 5.0 slots, six SATA ports, four M.2 positions with cooling plates, front USB-C with Power Delivery, and two USB 3.0 headers for a case with a lot going on. The aluminum cover and heatpipe over the VRM are the kind of detail you notice with the panel off, and there are more fan and ARGB headers here than most builds will ever use.

Where we cooled on it is the value question. The Carbon's headline extras — the second Gen5 slot, the extra SATA ports, the shroud — are exactly the ones a one-GPU, two-drive build never touches, and you're planning the whole build around its slot spacing to get them. Do that planning and it's a genuinely nice board. Skip it and the Tomahawk does the same work with fewer constraints.
