This article covers Gigabyte Z790 Dマザーボード.

Overview

The GIGABYTE Z790 D is an ATX motherboard built around the Intel Z790 Express chipset, supporting LGA1700 processors from the 12th, 13th, and 14th generations. It features a 12+1+1 phase digital VRM design, making it a solid choice for mid-range builds that need stable power delivery for Core i5 through Core i7 CPUs.
This board supports DDR5 memory up to 7600MHz (OC) and includes three PCIe 4.0 M.2 slots, giving you plenty of room for fast storage. It also comes with 2.5GbE LAN, a rear USB-C 10Gbps port, and Q-Flash Plus for BIOS updates without a CPU installed.
Priced around ¥42,000–¥44,000, the Z790 D sits at the affordable end of the Z790 lineup. It's a great option for builders who want DDR5 and modern connectivity without paying a premium for flagship features.

Compatibility Guide

The motherboard uses the LGA1700 socket and works with Intel Core 14th Gen (Raptor Lake Refresh), 13th Gen (Raptor Lake), and 12th Gen (Alder Lake) processors. Memory support is DDR5 only, with four DIMM slots and XMP 3.0 profiles for easy overclocking.
Form factor is standard ATX, fitting most mid-tower and full-tower cases. Power delivery uses a 24-pin main connector plus one 8-pin CPU power connector. A 650W PSU is sufficient for Core i5 builds, but we recommend 750W or higher if pairing with a Core i7/i9 and a high-end GPU.
Storage options include three PCIe 4.0 x4 M.2 slots and four SATA 6Gbps ports. The primary PCIe x16 slot runs at PCIe 4.0 and features an EZ-Latch quick-release mechanism for easy GPU removal.

Product Info

The GIGABYTE Z790 D launched in early 2024 as a value-oriented Z790 motherboard. Its market position is "entry-to-mid-range DDR5 enabler" — it strips away unnecessary extras while keeping the core features that matter for most builders.
Key specs include a 12+1+1 phase VRM, DDR5 support up to 7600MHz (OC), three PCIe 4.0 M.2 slots, 2.5GbE LAN, a rear USB-C 10Gbps port, and DisplayPort/HDMI outputs. Q-Flash Plus allows BIOS updates without a CPU or memory installed.
Warranty is three years for official Japanese retail units. The board is widely available through major electronics retailers and online stores.

Best Use Cases

  • First-time PC builders on a budget: The Z790 D offers DDR5 and PCIe 4.0 at a reasonable price. Pair it with a Core i5-14400F or i5-13600K for a balanced gaming rig that won't break the bank.
  • Users upgrading from DDR4: If you're building a new system and want to move to DDR5, this board gives you a cost-effective entry point. XMP 3.0 support means you can take advantage of high-speed memory kits.
  • Storage-focused builders: With three PCIe 4.0 M.2 slots, you can run multiple fast NVMe drives for game libraries, project files, and OS without SATA bottlenecks.
  • Users who don't need extreme overclocking: The 12+1+1 phase VRM is adequate for stock and mild OC on Core i7-class CPUs. If you plan to push a Core i9-14900K to its limits, consider a higher-end Z790 board with more VRM phases.

Things to Consider

This motherboard does not support PCIe 5.0. The primary PCIe x16 slot and all M.2 slots are PCIe 4.0. If you plan to use a future PCIe 5.0 GPU or SSD, you'll need a more expensive Z790 board like the AORUS MASTER or AERO G.
There is no onboard Wi-Fi or Bluetooth. You'll need to add a Wi-Fi card or USB adapter if wireless connectivity is required.
The 12+1+1 phase VRM is sufficient for Core i7 and below, but sustained heavy loads on a Core i9-14900K may push VRM temperatures higher than on premium boards. Good case airflow or a top-flow CPU cooler can help mitigate this.

FAQ

Q: Can I use a Core i5-14400F with this board?
A: Yes, absolutely. The LGA1700 socket supports 14th Gen CPUs out of the box, and the 12+1+1 phase VRM handles Core i5 with ease. It's a great budget-friendly pairing.
Q: Will DDR5-6000 memory work?
A: Yes, it will. The board supports XMP 3.0 and is validated for memory speeds up to 7600MHz (OC). For best stability at high speeds, use two DIMMs rather than four.
Q: Can I install a PCIe 5.0 graphics card?
A: Physically yes, but it will run at PCIe 4.0 x16 speeds. Current GPUs like the GeForce RTX 40 series and Radeon RX 7000 series don't saturate PCIe 4.0 x16, so real-world performance impact is negligible.
