This article covers GIGABYTE Z790 UD AX​ ​[intel Z790 チップセット搭載 ATX マザーボード]​ MB5930.

Overview

The GIGABYTE Z790 UD AX is a well-rounded entry-level motherboard for Intel's 12th and 13th Gen processors. It brings PCIe 5.0, DDR5, and WiFi 6E to a price point that won't break the bank. With 16+1+1 phase DrMOS power delivery, it handles most mainstream CPUs with ease. This board is ideal for builders who want a future-proof foundation without spending on premium features they may not need.

Compatibility Guide

The LGA 1700 socket supports Intel Core i5-13600K, i7-13700K, and even i9-13900K, though the latter may stress the VRM under heavy loads. DDR5-5600 is the official max, but faster kits may work with overclocking. Four DIMM slots allow up to 128 GB. The ATX form factor (305×244 mm) fits most standard cases. Storage: three PCIe 4.0 x4 M.2 slots and six SATA 3.0 ports, with RAID 0/1/5/10 support. The primary PCIe slot is Gen 5.0, but it's backward compatible. Power: 24-pin ATX + 8-pin EPS, recommended PSU 650W+.

Product Info

Released in Q4 2022, the Z790 UD AX is positioned as a budget-friendly Z790 option. It commonly sells for around ¥17,636 in Japan. Warranty: 2 years via official Japanese distributors. Key specs: 16+1+1 phase VRM, PCIe 5.0 x16, three PCIe 4.0 M.2 slots, Realtek 2.5GbE LAN, WiFi 6E (RZ616), Realtek ALC897 audio, HDMI 2.0 and DisplayPort 1.2 outputs.

Best Use Cases

  1. Budget Gaming Build: Pair with an i5-13600K and RTX 4060/4070 for solid 1440p gaming. The DDR5 and PCIe 5.0 support future GPU upgrades. 2. Productivity PC: For office work, light video editing, or programming, the board offers stable performance with ample storage options. 3. WiFi-Ready Desktop: Integrated WiFi 6E and Bluetooth 5.2 make it perfect for users who need wireless connectivity without extra adapters. 4. Not ideal for: Enthusiasts who want extreme overclocking or multiple PCIe 5.0 GPUs; high-end Z790 boards are better suited.

Things to Consider

The VRM heatsink is modest, so prolonged heavy use with an i9-13900K may cause thermal throttling. The audio codec is basic; audiophiles should consider an external solution. There's only one PCIe 5.0 slot, and the second PCIe x16 slot runs at PCIe 4.0 x4. The board lacks a BIOS flashback button, which can be a concern if you need to update the BIOS without a supported CPU. Competitors like ASUS Prime Z790-P and MSI PRO Z790-P offer similar features; check specific I/O needs. ## FAQ
Q: Can I use an i7-13700K with this board? A: Yes, the 16+1+1 phase VRM handles i7-13700K well. Ensure adequate case airflow for sustained loads. Q: Does it support DDR5 overclocking? A: Yes, XMP profiles are supported. Officially rated for DDR5-5600, but many users have reported stability with DDR5-6000 kits. Q: Is there a BIOS flashback feature? A: No, this model does not have a BIOS flashback button. You need a compatible CPU to boot and update the BIOS.
