This article covers GIGABYTE Z790 AORUS PRO X intel 第13世代CPU対応 LGA1700 DDR5 ATX マザーボード MB6273.

Overview

The GIGABYTE Z790 AORUS PRO X is a high-end ATX motherboard built for Intel 12th and 13th Gen Core processors. It packs a Z790 chipset, DDR5 memory support, PCIe 5.0 x16 slot, and multiple high-speed M.2 slots. The 18+1+2 phase digital power design with 90A SPS ensures stable power delivery even for flagship CPUs like the Core i9-13900K. Connectivity is a standout feature: 5GbE wired LAN, WiFi 7 (functioning as WiFi 6E in Japan due to local regulations), and two USB3.2 Gen2x2 Type-C ports (front and rear). The unique VisionLink function allows passing the discrete GPU signal through the rear USB-C port to a tablet, reducing cable clutter while maintaining high graphics performance. Positioned as a high-end Z790 board, the AORUS PRO X balances expansion, networking, and unique features at a competitive price point (normally around ¥40,000 before tax).

Compatibility Guide

Socket: LGA1700, compatible with Intel 12th Gen (Alder Lake) and 13th Gen (Raptor Lake) Core processors. Memory: 4x DDR5 DIMM slots, max 192GB (48GB per DIMM). Supports XMP 3.0 profiles. Form factor: ATX (305×244mm), fits most mid-tower or larger cases. Expansion slots: 1x PCIe 5.0 x16 (primary GPU slot), 1x PCIe 4.0 x4, 1x PCIe 3.0 x4. Storage: 5x M.2 slots (1x Gen5, 4x Gen4) and 4x SATA 3.0 ports. Power: main 24-pin ATX + two 8-pin CPU EPS connectors. For a high-end CPU and GPU, we recommend an 850W or higher power supply.

Product Info

Released in late 2023. Japanese model number MB6273, distributed by official GIGABYTE Japan partners with a 2-year warranty. The Japan price around ¥3,980 appears to be an error or flash sale; typical retail is ¥38,000–¥45,000. Key specs: Z790 chipset, 18+1+2 phase 90A SPS VRM, Intel 5GbE LAN, WiFi 7 (MediaTek chipset, 6E in Japan), Realtek ALC4080 audio with high-end capacitors. The board also features EZ-Latch for easy GPU and M.2 removal.

Best Use Cases

First, high-end gaming builds. With PCIe 5.0 support for graphics cards and SSDs, plus ample M.2 storage, this board can handle the fastest components for 4K gaming or high-refresh-rate 1440p. Second, content creation workflows. Multiple M.2 slots allow RAID configurations for video editing, and the stable VRM ensures no throttling during long renders. Third, creative professionals using a pen display tablet. VisionLink lets you route the GPU signal to a USB-C tablet without extra cables, while also providing power and data over the same connection. ## Alternatives
Direct competitors include the ASUS ROG STRIX Z790-E GAMING WIFI II and MSI MPG Z790 CARBON WIFI. Both offer similar VRM quality and PCIe 5.0 support. The ASUS board tends to cost more but has a more mature BIOS ecosystem. The MSI model also includes WiFi 7 but lacks VisionLink. If you specifically need dual Thunderbolt 4 ports or more rear USB-C, the ASUS ROG Maximus Z790 Hero is another option. For most users, the GIGABYTE offers the best value with its storage expandability and unique tablet feature.

Things to Consider

First, DDR5-only means existing DDR4 kits cannot be reused, increasing total build cost. Second, WiFi 7 is not fully operational in Japan yet; you'll get WiFi 6E speeds until the 6GHz band is approved. Third, the extremely low ¥3,980 price tag on may be a listing error or third-party scalp pricing. Verify the seller's reputation before purchasing. Fourth, while the VRM is robust, pairing with a Core i9-13900K and overclocking will require a high-end CPU cooler and good case airflow to keep temperatures in check.
