Overview

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.

Advance Your Gaming Immersion

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.

All-round Performance

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.

Play Your Own Style

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.

CERTIFIED COMPATIBILITY

ROG Strix motherboards undergo an extensive certification program to ensure the very best compatibility with the widest range of components and devices. For a smooth build process, refer to our list of guaranteed-compatible components. To help with memory upgrades, the list also includes a dedicated Qualified Vendor list (QVL).

The ROG Strix Ecosystem Awaits

New to this generation, GameFirst VI features AI-enhanced identification and boost technology to ensure faster and smarter network optimisation.

Armoury Crate

Armoury Crate is a new software utility designed to give you centralised control of supported gaming products, making it easy to tune the look and feel of your system.

Bit expensive for a B550 board but performs and looks great with my black and white themed build. Has lots of room for expansion.

December 2022

A solid mobo for great gaming performance, but do understand that it's not a recent design now (Dec 2022) and as such, in a case sporting USB-C on the front panel, is doesn't have a USB 3.2 Gen 2 Header e.g. for a Corsair 4000D airflow case, so you'd either need an adapter or PCI card providing a USB 3.2 Gen 2 Header. Besides this, great BIOS, good layout and good quality components.

Easy to fit. First ever build, all worked well.

Brilliant motherboard. Not too pricey and works really well.

Very high quality board for the price and it looks terrific in white. My only gripe is that the stock pictures of the board give the impression that it has RGB elements on it - it doesn't, the chipset heatsink and the rear I/O cover have lettering on them that creates a holographic/ rainbow effect when the light catches it. My own fault for not checking properly but the pictures are a little misleading.
