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.
Dr.MOS is the integrated power stage solution which is optimized for synchronous buck-set down voltage applications! Compared to traditional discrete MOSFETs, it intelligently delivers higher current for each phase, thus providing improved thermal result and superior performance.
Featuring sturdy components and completely smooth power delivery to the CPU, offering enhanced performance for gamers.
The 6 Layer PCB provides stable signal traces and power shapes delivering lower temperature and higher energy efficiency for memory overclocking! Thus, it's able to support the latest memory modules with most extreme memory performance!
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.
Whether you are using headphones, a headset, external or internal speakers, via USB, Wi-Fi, analog output or even HDMI, Nahimic Audio offers you the most engaging listening experience, vibrant and rich with details.
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.
*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.
This motherboard is capable of accomadating multiple M.2 storage devices, one of which can support PCI Express 4.0 M.2 SSD, it is capable of performing twice the speed compared to previous 3rd generation, giving a lightning fast data transferring experience.
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.
BFB Technology allow the use of increasing TDP to enjoy the base frequency boost with the hidden power of processors with users' non K series CPUs and ASRock’s selected 600 series motherboards
While ASRock BFB breathes life into non K series CPUs, the boost frequency currently still depends on the cooling system applied on your rig.
BFB frequency performance results may vary between different CPUs and hardware configurations.
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.
Get the most convenient BIOS flashing with just a simple click. Users can easily achieve the latest BIOS support with a USB and power supply, No CPU, RAM or other components required.
Besides the onboard LAN port, users may also choose 802.11ac wireless connections by M.2 (Key E) slot.
*Wi-Fi module is not included.
