Best Z790 Motherboards of 2026

Take the top pick, remove one M.2 slot and a few power stages, and hand back a meaningful slice of the price: that's the Eagle AX, and for a lot of builds it's the better trade. It keeps the parts that date badly — DDR5 across four DIMM slots, a PCIe 5.0 graphics slot, WiFi 6E, 2.5-gigabit Ethernet and USB-C — and trims where most people never look.

For an i5-14600K or a 14700K with a mild overclock, we think this is the smartest spend in the group. It boots and configures without drama, the BIOS is forgiving if you have never set XMP before, and it will take a 14th-gen chip without a fight.

GIGABYTE's build-day tools are the quietly useful part. Q-Flash updates the firmware from a USB stick without a CPU or memory installed, EZ-Latch releases the graphics card without a screwdriver, and the M.2 Thermal Guard covers the drives that run hot. None of that shows up in a feature comparison, and all of it shortens a build.

Where it gives ground: three M.2 slots instead of four, 12+1+1 power stages that are the lightest in this group, and ARGB headers only, with no 12-volt RGB for older light strips. A gaming build with two drives and an air cooler never notices; a showcase machine built around a 14900K will.

Silver heatspreaders, a white rear I/O cover and a light gray board: the ROG Strix Z790-A Gaming WiFi II is one of the few boards here built to be looked at, and it's the pick for a white or silver build where a black PCB would spoil the effect. The finish is the reason to start reading, not the reason to buy.

Underneath it is a serious board. Power delivery is 16+1+2 stages rated at 70A with dual ProCool II connectors, the VRM heatsinks are joined by an L-shaped heatpipe, and the front-panel USB-C connector pushes up to 30W of power delivery — enough to charge a phone or run a bus-powered drive from the case front instead of reaching around the back.

Five M.2 slots is the number we keep coming back to. Most boards here give you three or four; this one takes a boot drive, a games drive, a scratch drive and still has room, and each slot gets a heatsink. What it doesn't have is a Gen 5 M.2 slot — all five are PCIe 4.0, with 5.0 reserved for the graphics card — so if a Gen 5 SSD is already on your desk, this isn't the board for it.

Two things to plan around. The VRM cover is tall, so dry-fit a large top-mounted air cooler before you commit. And first-boot and memory stability are worth confirming early: populate the slots, enable XMP and run a memory test while the board is still returnable.

This is the cheapest route to a Z790 chipset in this group, and the one we point to when the budget is fixed and the build still has to be sound. The hardware is not the compromise: DDR5 across four slots, a PCIe 5.0 graphics slot, WiFi 6E, Bluetooth 5.3, 2.5-gigabit Ethernet and USB 3.2 Gen 2.

The compromise is the refurbished part. Coverage runs 90 days instead of the three years a new board gets, and condition varies — units arrive looking untouched, and units arrive with residue on the backplate or a bent I/O cover. For a second machine, a home server or a first build on a tight budget, the savings are worth that risk as long as you buy somewhere with a generous return window and open the box the day it lands.

Test the things a refurbished board can hide. Inspect the CPU socket under good light for bent pins, confirm every DIMM slot posts, and check that both the wired and wireless adapters show up in Windows before you install anything else. A dead slot is a day-one problem, not a month-six surprise, which is exactly why the return window is part of the purchase.

It is also the plainest board here — no shrouds, no styling, nothing to show through a side panel. For a build that lives under a desk, that's a fair trade rather than a fault.

Two 8-pin CPU power connectors, 16+1+1 Duet Rail stages, a PCIe 5.0 slot, WiFi 6E, 2.5-gigabit Ethernet, Bluetooth 5.3 and M.2 Shield Frozr across the storage: the Tomahawk's hardware list reads like a board that costs more, and in black it disappears behind a tempered-glass panel the way a gaming build usually wants.

For a machine where you want the header count and the heatsinks without paying for white paint or a halo badge, it's a sensible choice. The port selection is generous, everything snaps into place without force, and the M.2 shields mean you're not hunting for a tiny screwdriver mid-build.

First boot is the part to plan for. Power-up failures are the recurring risk on this model, so assemble it outside the case, confirm it posts with a single stick of memory, and keep the box until the return window closes. Have the network drivers on a USB stick before Windows: Setup often doesn't see this board's Ethernet or WiFi adapter until they're installed.

Longevity is the other open question — boards that give up inside the first year come up often enough that registering the three-year warranty on day one is worth the five minutes. It's a fine board at a fair position in this group; it just isn't the one we hand to someone who wants a quiet first afternoon.
