The ASRock X670E Steel Legend motherboard, a reliable motherboard produced under ASRock's consistently stringent quality control. It delivers excellent performance with robust design conforming to ASRock's commitment to quality and endurance.

  • SPS (Smart Power Stage)
    Dr.MOS design features the SPS (Smart Power Stage) technology. It's optimized for monitoring current and temperature of each phase, thus delivering smoother and neater power to the CPU with enhanced performance and OC capability.
  • 16+2+1 power phase design
    Featuring sturdy components and completely smooth power delivery to the CPU. Plus, it offers unmatched overclocking capabilities and enhanced performance with the lowest temperature for advanced gamers as well.
  • Server Grade Low Loss PCB
    The server grade low loss PCB improves signal integrity, allowing motherboard to support PCIe 5.0 for both graphics card and M.2 SSD, it also improves memory OC potential to deliver the most extreme memory performance.
  • 8 Layer PCB
    The 8 Layer PCB provides stable signal traces and power shapes delivering lower temperature and higher energy efficiency, ensures a reliable and long-lasting system while delivering ultimate performance without any compromise.
  • DDR5 EXPO and XMP support
    Derived from the "built for stable and reliable" designing concept, ASRock does not compromise on any details. All X670E motherboards are built with 8-Layer and premium low-loss materials, enthusiasts are able to enjoy the boost of DDR5 memory overclocking performance up to 6600 MHz and beyond by enabling the pre-tested profiles. Make sure the memory modules are AMD EXPO/Intel XMP capable and overclocking can be made so affordable, satisfying and absolutely no sweat at all.
  • Blazing OC Tuner
    The Blazing OC Tuner allows AM5 CPU to switch between OC mode and PBO (Precision Boost Overdrive) mode when the CPU current hits threshold. Anything above current threshold will engage manual OC mode; if below current threshold, then will engage Precision Boost Overdrive mode. This idea is to combine overclocking on all cores and automatic boost on a single core to get the best performance out of your CPU. There is no need to enter BIOS to setup up, you can modify all the settings on time under OS.
  • AMD PBO technology
    PBO (Precision Boost Overdrive) is an automatic performance-maximizing technology that is able to improve your PC's performance by raising clock speeds based on the conditions inside your PC, AMD's processors are equipped with intelligent thermal sensors designed to analyze conditions inside your PC and make the "go faster" decision as often as possible, please ensure system cooling is sufficient before enabling PBO.
  • Reinforced DIMM slot
    The reinforced DIMM slot is surfaced mounted onto the motherboard to give better physical strength as well as a more stable memory signal, with this superior revolutionary design, it is able to dramatically overclock DRAM module up to insane frequency.
  • DIY friendly design
    Due to the unique electrical architecture of DDR5 DIMM, there's a high risk of damaging the memory module if AC power isn't disconnected properly during removal or installation. To prevent this, ASRock has implemented a trouble-free protection circuit on every DDR5 motherboard, lowers the risk of damaging your memory module.
  • PCIe Gen5 Blazing M.2
    The Blazing M.2 accommodates the PCI Express 5.0 standard to perform twice the bandwidth compared to previous generation, with a breathtaking 128 Gbps transfer speed, it is ready to unleash the full potential of future ultrafast SSDs.
  • XXL M.2 heatsink
    The extra-large aluminum alloy M.2 heatsink effectively improves heat dissipation to keep those high-speed M.2 SSDs as cool as possible, it is able to give better stability while maintaining top performance.
  • 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 Gbps LAN
    The intelligent 2.5 Gbps 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.
  • Wi-Fi 6E 802.11ax
    Wi-Fi 6E technology has extended to the 6 GHz spectrum band, providing more Wi-Fi capability and giving an even better and faster Internet traffic. In addition to deliver higher speeds, the Wi-Fi 6E also enhances the lower latency and supports service levels that are equivalent to 5G networks.
  • Front USB 3.2 Gen2x2 Type-C
    The 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.
