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. A motherboard that fulfills every task â with style!

ULTRA USB POWER ULTRA STABLE POWER +5V voltage is transferred from the +12V. Supplying enough current to USB devices without dropping voltage directly from the PSU.

ANTISTATIC SHIELD Protect mouse/keyboard against static electricity, especially lowering the chances of USB mouse lag or stuttering.

PURE AUDIO QUALITY USB speaker is suggested to be connected via Ultra USB Power ports to perform the pure current and offer high audio quality without distortion.

XXL Aluminum Alloy Heatsink Extra large aluminum alloy heat sinks that effectively take away heat from the MOSFET and chipset so that your whole system may perform more stable.

Premium 60A Power Choke Compared to traditional chokes, ASRockâs premium 60A power chokes effectively make the saturation current up to three times better, thus providing enhanced and improved Vcore voltage to the motherboard.

Nichicon 12K Black Caps Supreme 12K black capacitors with lifespans of at least 12,000 hours. Compared to other counterparts on high-end motherboards that merely have lifespans of around 10,000 hours, ASRock applied Nichicon 12K Black Caps that offer 20% longer lifespans and provide more stability and reliability.

I/O Armor A new designed protective cover for all of the crucial parts near the motherboard's rear I/O, so that they won't easily be damaged by static electricity.

Sapphire Black PCB Pure black PCB appearance. The new Sapphire Black PCB represents rock-solid quality and gives the motherboard a more mysterious touch.

High Density Glass Fabric PCB High Density Glass Fabric PCB design that reduces the gaps between the PCB layers to protect the motherboard against electrical shorts caused by humidity.

2oz Copper PCB Using only carefully selected copper materials for PCB layers, 2oz Copper PCB delivers lower temperature and higher energy efficiency for overclocking.

Full Spike Protection Some sensitive digital components on the motherboard are vulnerable to power surges, the excessive current may cause your system to malfunction immediately. ASRock Full Spike Protection includes various technologies to prevent your motherboardâs components from being damaged by these unexpected voltage spikes.

Live Update & APP Shop ASRock Live Update & APP Shop is designed for your convenience. We provide various apps and support software for users to download. You can also easily optimize your system and keep your motherboard up to date with ASRock Live Update & APP Shop.
