Overview

The ASRock Z890 Pro RS is an ATX motherboard built around Intel's Z890 chipset, designed for the latest Core Ultra processors (Arrow Lake) with the LGA1851 socket. It supports DDR5 memory and PCIe 5.0, positioning it as a solid mid-range option for builders who want modern features without breaking the bank. Priced around ¥28,000 in Japan, this board offers excellent value for a Z890 platform. It's suitable for gaming, content creation, and general high-performance PC builds, especially when paired with a Core Ultra 7 or 9 CPU.

Compatibility Guide

CPU socket: LGA1851 – compatible only with Intel Core Ultra series (no backward compatibility with LGA1700). Memory: 4 x DDR5 DIMM slots, up to 256GB, with support for overclocked speeds up to 8666 MHz (OC). Form factor: Standard ATX – requires a case that supports ATX motherboards. Chipset: Intel Z890 provides PCIe 5.0 lanes (one x16 from CPU), plus additional PCIe 4.0/5.0 lanes from the chipset. Storage: Multiple M.2 NVMe slots and SATA ports – check the exact lane configuration on the official page. Power: 24-pin main + 8-pin and 4-pin CPU power connectors. For a high-end build, a PSU of 850W or higher is recommended.

Product Info

Released in late 2024, the Z890 Pro RS is a mid-range motherboard that balances features and cost. It supports Intel's Z890 chipset, DDR5 memory, PCIe 5.0, and USB 3.2 Gen2x2. The warranty is standard 3 years for authorized Japanese retail units. It is available through major online retailers like .

Best Use Cases

Core Ultra PC builders: The Z890 Pro RS is a cost-effective way to get into the LGA1851 platform, offering overclocking support for Core Ultra 7 and 9 chips. Gamers wanting DDR5 and PCIe 5.0: Pair it with a fast DDR5 kit and a PCIe 5.0 GPU for high frame rates. Note that PCIe 5.0 SSDs may not be fully supported on all M.2 slots. Budget-conscious enthusiasts: This board provides essential Z890 features (OC, PCIe 5.0, ample USB) at a lower price than premium models, making it ideal for builders who want to allocate budget to other components. Not ideal for: Users who want to reuse LGA1700 CPUs (incompatible socket). Those building a small form factor PC (only ATX). Users who need built-in Wi-Fi/Bluetooth (optional add-on required).

Things to Consider

The Z890 Pro RS lacks onboard Wi-Fi and Bluetooth. If you need wireless connectivity, you'll have to install a separate M.2 Key E Wi-Fi card or use a USB adapter. While the board supports PCIe 5.0, its M.2 slots are limited; some slots may only run at PCIe 4.0. If you plan to use a PCIe 5.0 SSD at full speed, consider a higher-end model like the Z890 Pro RS WiFi. Memory overclocking to 8666 MHz is supported, but real-world stability depends on your CPU's memory controller and the quality of your RAM kit. For reliable operation, sticking to the rated JEDEC speeds is safer. ## FAQ
Q: Can I use a Core Ultra 5 processor with this motherboard? A: Yes, Core Ultra 5 (LGA1851) is compatible. However, if you only need stock performance, a B860 chipset board might be more economical. Q: Does this motherboard support Windows 11? A: Yes, it is officially listed as Windows 11 compatible and includes TPM 2.0 support. Q: Which PCIe slot should I use for my graphics card? A: Use the top PCIe x16 slot (CPU-attached) for best performance, as it runs at PCIe 5.0. Other slots are chipset-attached and may have limited bandwidth.
