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. A motherboard that fulfills every task – with style!

XXL Aluminum Alloy Heatsink & Heatpipe Design

Extra-large aluminum alloy heatsink along with heatpipe that effectively take away heat from the MOSFET, so that your whole system may perform more stable.

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.

RULE YOUR OWN LIGHTING WAY - POLYCHROME RGB

ASRock motherboards deliver stunning performance and superior aesthetics to rule your own colorful lighting way! ASRock offers a very comprehensive control to perform the built-in RGB LEDs or the connected LED strips, CPU fans, coolers, chassis and any RGB devices smoothly. Devices can be synchronized across the Polychrome RGB Sync-certified accessories as well.

*The addressable RGB LED header supports WS2812B addressable RGB LED strip (5V/Data/GND), with a maximum power rating of 3A (5V), a max of 80 LEDs and length within 2 meters.
*The RGB LED header supports standard 5050 RGB LED strip (12V/G/R/B), with a maximum power rating of 3A (12V) and length within 2 meters.

Dual M.2 For SSD

Two of the world’s fastest M.2 slots. One delivers up to PCIe Gen3 x4 32Gb/s transfer speed, the other one supports SATA3 6Gb/s mode.
