This article covers ASRock マザーボード Z790 Lightning WiFi Intel 第12世代 ・ 13世代 CPU （ LGA1700 ）対応 Z790チップセット DDR5 ATX マザーボード 【国内正規代理店品】.

Overview

The ASRock Z790 Lightning WiFi is an ATX motherboard built on the Intel Z790 chipset, supporting 12th, 13th, and 14th Gen Core processors (LGA1700). It offers DDR5 memory support with four DIMM slots and a robust 16+1+1 Dr.MOS power phase design for stable CPU power delivery. The 8-layer PCB enhances signal integrity and thermal performance. With integrated Wi-Fi and a quick-release M.2 heatsink, this board aims to provide a cost-effective yet feature-rich platform for gamers and creators.

Compatibility Guide

The motherboard uses the LGA1700 socket and is compatible with Intel Core 12th Gen (Alder Lake), 13th Gen (Raptor Lake), and 14th Gen (Raptor Lake Refresh) processors. It supports DDR5 memory only, with four slots and a maximum capacity of 192GB. Overclocked speeds up to DDR5-7600+ are supported. The ATX form factor fits standard ATX cases. Power delivery requires a 24-pin ATX main connector and 8+4-pin CPU power. A PCIe 5.0 x16 slot is available for modern graphics cards. Storage options include M.2 slots and SATA III ports.

Product Info

Released in 2023, the Z790 Lightning WiFi is positioned in the mid-to-upper range segment. It is sold in Japan as an authorized distributor product, typically priced around ¥29,500, offering excellent value for its feature set. The 16+1+1 phase VRM delivers sufficient power for Core i7/i9 processors under normal use. The board includes built-in Wi-Fi and Bluetooth. The warranty is standard one year (with possible extension from retailers).

Best Use Cases

This motherboard is ideal for budget-conscious gamers building a DDR5 system. The Z790 chipset and PCIe 5.0 support ensure compatibility with the latest GPUs and fast storage. It also suits content creators who need stable performance for video editing and rendering. Additionally, it is a good choice for first-time PC builders due to its straightforward layout and competitive price point.

Things to Consider

The Z790 Lightning WiFi lacks a BIOS Flashback feature, meaning updating the BIOS for a new CPU requires an existing compatible processor. It only supports DDR5 memory, so users with DDR4 kits must upgrade. Overclocking headroom is adequate but not extreme; heavy overclockers may prefer boards with more advanced cooling. Ensure adequate case airflow when using high-TDP CPUs.
