Z790 ATX motherboard for 12th to 14th Gen Intel

The GIGABYTE Z790 D AC uses the LGA 1700 socket and Intel Z790 chipset to support 12th, 13th and 14th Generation Intel Core, Pentium Gold and Celeron processors. Four 288-pin DDR5 slots accept up to 192 GB in dual-channel mode with speeds ranging from 5200 to 7600 MT/s when overclocked. The board targets builders who want current-generation Intel performance on a standard ATX platform.

Fully covered MOSFET heatsinks

A twin 12+1+1 phase digital VRM is cooled by fully covered MOSFET heatsinks, while an M.2 Thermal Guard protects the primary SSD from throttle-inducing heat. The 6-layer PCB uses 2X copper for lower resistance and better heat spreading. Smart Fan 6 provides multiple temperature headers and hybrid fan-pump control so cooling stays proportional to load without unnecessary noise.

PCIe 5.0 graphics slot

The top PCIe 5.0 x16 slot takes full-bandwidth graphics cards, while the chipset adds one PCIe 4.0 x4 slot, two PCIe 3.0 x1 slots and one PCIe 3.0 x1 slot. Three M.2 sockets — one CPU-attached PCIe 4.0 x4, two chipset-attached PCIe 4.0 x4 — support 2280 and 22110 NVMe SSDs. Rear I/O includes USB 3.2 Gen2x2 Type-C at 20 Gbps and 2.5 GbE LAN driven by a Realtek controller. Q-Flash Plus updates BIOS without a CPU or memory installed.

Questions about this item

How do I install the board and what step is often missed with the PCIe 5.0 slot?

Mount the ATX board using standard standoffs, connect the 24-pin and 12V power cables, then install the graphics card in the top PCIEX16 slot running at PCIe 5.0 x16; the step people miss is forgetting to engage the PCIe EZ-Latch release before pulling the card out later.

What maintenance will the M.2 Thermal Guard and VRM heatsinks need later?

The fully covered MOSFET heatsinks and M.2 Thermal Guard are passive; periodically blow dust from the fins and check that the thermal pads on the three M.2 slots remain seated when swapping drives.

What limit appears first under sustained load with the 14-phase digital VRM?

The 14+1+1 phase digital VRM is rated for high current; under sustained heavy load the first limit is typically VRM temperature, so ensure case airflow reaches the heatsink array and adjust Smart Fan 6 curves if needed.
