This article covers ASRock マザーボード Z790 Pro RS.
Overview
The ASRock Z790 Pro RS/D4 is an ATX motherboard built around the Intel Z790 chipset, supporting LGA1700 socket for 12th and 13th Gen Intel Core processors. It features DDR4 memory support, making it a cost-effective choice for users who want to reuse existing DDR4 RAM. The board boasts a robust 14+1+1 power phase design with 50A Dr.MOS, ensuring stable power delivery even under overclocking. It also includes a front USB 3.2 Gen2x2 Type-C port delivering 20Gbps transfer speeds. With its clean aesthetics and solid feature set, this motherboard targets the mid-range to upper-mid-range market segment.
Compatibility Guide
This motherboard supports LGA1700 CPUs from Intel's 12th and 13th generations. It uses DDR4 memory exclusively (4 DIMM slots, dual-channel, up to 128GB). The form factor is standard ATX, requiring a compatible case. Power connectors include a 24-pin ATX main connector and an 8-pin EPS 12V connector. Storage options include multiple SATA 3 ports and several M.2 slots with PCIe 4.0 x4 support. An M.2 Key E slot allows adding a wireless module for Wi-Fi and Bluetooth connectivity. Please note that DDR5 memory and PCIe 5.0 devices are not supported.
Product Info
Released in late 2022, the ASRock Z790 Pro RS/D4 is positioned as a mid-range motherboard offering excellent value. It typically retails for around ¥27,000 (approx. $180-190 USD) and comes with a standard 1-year warranty in Japan. The 14+1+1 VRM design is impressive at this price point, enabling stable operation with high-core-count CPUs. The board's key differentiator is its support for DDR4, allowing users to save on memory costs. It is widely available through major retailers and e-commerce platforms.
Best Use Cases
This board is ideal for users building a gaming or productivity PC with Intel 12th/13th Gen CPUs, especially those who already own DDR4 memory and want to avoid the higher cost of DDR5. It works well with Core i5-13400 and Core i7-13700 processors for gaming and content creation. The M.2 Key E slot makes it a good choice for users who need built-in Wi-Fi but prefer to choose their own wireless module. It also suits minimalist PC builders who appreciate a clean, unobtrusive board design.
Things to Consider
The lack of DDR5 support limits future upgrade potential; if you plan to keep the system for many years, a DDR5 board might be more future-proof. Additionally, the board does not support PCIe 5.0, so the latest generation of graphics cards and SSDs will run at PCIe 4.0 speeds (which is still sufficient for most current workloads). The VRM heatsink is adequate but not overkill—extreme overclocking with a Core i9-13900K may push thermal limits. Competing boards from Gigabyte and MSI offer similar features at comparable prices, but the ASRock stands out for its cost-friendly DDR4 approach.
