ASUS ROG STRIX B550-A Gaming Motherboard AMD AM4

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.

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.

Cooler by Design

ROG Strix B550 series features the most comprehensive cooling options ever, configurable via Fan Xpert 4 or the UEFI BIOS.

6-LAYER PCB

The 6-layer PCB quickly dissipates heat around the VRM to improve overall system stability and give the CPU more overclocking headroom.

TEAMED POWER STAGES

12+2 power stages combine high-side and low-side MOSFETs and drivers into a single package, delivering the power and efficiency that the AMD CPUs demand.

PROCOOL POWER CONNECTOR

The ProCool socket is built to exacting specifications to ensure flush contact with the PSU power lines, enabling lower impedance and better heat dissipation.

DIGI+ POWER CONTROL

ASUS DIGI+ Power Control is an innovative set of controllers for digital VRM and DRAM Voltage. These controllers offer ultra precise memory and voltage tuning for optimal system efficiency, stability and performance.

ALLOY CHOKE & CAPACITOR

Superior chokes and durable capacitors are engineered to resist extreme temperatures and provide up to 110% better performance than the industry standard.

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.

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.

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 customized Daisy Chain layout delivers time-aligned signaling.

Q-LEDs

Four onboard LEDs indicate power status, and any problem with the CPU, memory, graphics card or boot device for quick diagnosis.

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.
