Designed for those seeking to get the most out of their build, ROG Strix B550 Gaming series motherboards offer a feature-set usually found in the higher-end ROG Strix X570 Gaming series, including the latest PCIe® 4.0 connectivity. Offering robust power delivery and effective cooling, ROG Strix B550-A Gaming is well-equipped to handle 3rd Gen AMD Ryzen™ CPUs. As an added bonus, outstanding performance is complemented by a stunning silver-and-white finish and cyberpunk-inspired aesthetics that present a standout look.
ROG Strix B550-A Gaming is PCIe® 4.0-ready and provides the latest connectivity options for supersmooth networking and blisteringly fast file transfers. Audio enhancements give you a massive advantage, allowing you to pick up on the subtlest of cues for a completely immersive gaming experience.
PCIe 4.0-Ready
ROG Strix B550-A Gaming features two M.2 slots, one of which supports the latest PCIe 4.0 standard to provide maximum storage flexibility and the fastest data speeds available via the 3rd Gen AMD Ryzen platform. Both M.2 slots support up to the type 22110 socket and NVM Express® RAID for a performance boost.
Intel 2.5 Gb Ethernet
Onboard 2.5 Gb Ethernet gives your wired connection a boost, with speeds that are 2.5 times faster than standard Ethernet connections for speedy file transfers, lag-free gaming, and high-res video streaming.
SupremeFX
Built-in ROG SupremeFX audio technology ensures pristine audio for ROG Strix B550-A Gaming. Along with ensuring a flat frequency response for a neutral, detailed sound signature, it offers two front-panel outputs driven by op amps that deliver high-quality audio to gaming headsets.
ROG Strix B550-A Gaming provides robust power delivery to fuel Ryzen's cores, comprehensive cooling, and support for faster memory — so it has everything you need to load up your build with high-performance components for playing in the big leagues.
Cooler by Design
ROG Strix B550 series features the most comprehensive cooling options ever, configurable via Fan Xpert 4 or the UEFI BIOS.
ASUS OptiMem II
To provide AMD's latest CPUs unfettered access to memory bandwidth, motherboard trace routing has been reimagined with the ROG Strix B550-A Gaming. Integrated OptiMem II technology carefully maps memory signal pathways across PCB layers to reduce vias, and it also adds shielding zones that significantly reduce crosstalk. To further enhance overclocking headroom for fully stacked memory configurations, a highly customised Daisy Chain layout delivers time-aligned signaling.
The cyberpunk-inspired aesthetics of ROG Strix B550-A Gaming are accentuated by the bold slashes and cybertext. By pairing your rig with other products from the diverse ROG ecosystem, you can create a fully customised gaming setup that reflects your personal style.
UNDENIABLY ROG STRIX
Finished in stunning white and silver, and featuring the redesigned ROG logo and recessed cybertext markings on its I/O shroud, ROG Strix B550-A Gaming is an eye-catcher. These new design touches move ROG Strix boldly towards the future, while clearly reflecting its gaming roots.
Pre-mounted I/O shield
Patented I/O shield is finished in sleek matte black and comes pre-mounted to make it easy to install on the motherboard.
Q-LEDs
Four onboard LEDs indicate power status, and any problem with the CPU, memory, graphics card or boot device for quick diagnosis.
SafeSlot
The reinforced ASUS SafeSlot provides stronger PCIe device retention and greater shearing resistance.
BIOS FlashBack™
Users can place a BIOS file onto a FAT32-formatted USB drive and simply plug it into the USB BIOS FlashBack™ port and press a button to update the (UEFI) BIOS. Updates can be made even if memory or CPU aren't present.
