Steel Legend Overview

Steel Legend represents the philosophical state of rock-solid durability and irresistible aesthetics. Built around most demanding specs and features, the Steel Legend series aims at daily users and mainstream enthusiasts! Providing a strong array of materials/components to ensure a stable and reliable performance.

DDR5 XMP & EXPO Support

Derived from the “built for stable and reliable” designing concept, ASRock does not compromise on any details. This motherboard is built with low-loss materials, enthusiasts are able to enjoy the boost of DDR5 memory overclocking performance by enabling the pre-tested profiles. Make sure the memory modules are Intel® XMP/AMD EXPO™ capable and overclocking can be made so affordable, satisfying and absolutely no sweat at all.

PCIe 5.0 + Surface-Mount Tech

Compares to conventional DIP style PCIe slot, the SMT type PCIe slot improves signal flow and maximize stability under high speed, a key breakthrough to fully support the lighting speed of the latest PCIe 5.0 standard. The latest PCI Express 5.0 is capable to perform a breathtaking bandwidth of 128GBps, ready to unleash the full potential of future high end graphic cards.

ASRock Graphics Card Holder

Install your heavy graphics card on the holder; connect it to your motherboard and chassis with screws. Flexibly slide up and down to perfectly adjust the height required for your graphics card in place.

POLYCHROME RGB

In addition to the built-in RGB illumination, it also features onboard RGB headers and an addressable RGB header that allow motherboard to be connected to compatible LED devices such as strip, CPU fans, coolers, chassis and so on. Users may also synchronize RGB LED devices across the Polychrome RGB Sync-certified accessories to create their own unique lighting effects.

Dragon 2.5 Gb/s LAN

The intelligent 2.5Gb/s LAN platform is built for maximum networking performance for the demanding requirements of home networking, content creators, online gamers and high-quality streaming media. Boost networking performance up to 2.5X the bandwidth compared to the standard gigabit Ethernet, you’ll enjoy the faster and uncompromised connectivity experience for gaming, file transfers and backups.

Front USB 3.2 Gen2x2 Type-C

The latest USB 3.2 Gen2x2 Type-C delivers up to 20 Gbps data transfer rate which is 2x as fast as previous generation, providing a blazing fast data transfer interface with reversible USB Type-C design that fits the connector either way.

Built in eDP Signal Connector

Supports ASRock 13.3” Side Panel kit. An eDP signal connector is built with ASRock selected motherboards and supports two functions simultaneously - power and transmission of digital display signal. The connector reserves the room for upgrading with ASRock’s exclusive 13.3” Side Panel Kit. The ideal 13.3" Side Panel size will be perfectly matched standard form factor chassis and users can easily build a LCD display inside the PC, adding a sub-screen for monitoring PC status, or watching videos, doing streaming or working personalized tasks. This whole new concept of customization enables new possibilities for personalizing designs - doubles productivity or entertainment.
