Ultimate power design
To fully support the latest 3rd Gen AMD Ryzen™ processors, B550 motherboards equip with the ultimate power solution which is true direct, digital and multiple phases. After countless experiments and testing, GIGABYTE presents the unbeatable B550 motherboards for enthusiast. No Compromise and never stop to achieve higher.
10+3 phases pure digital VRM solution with low RDS(on) MOSFETs
GIGABYTE AORUS series motherboards use a 10+3 phases pure digital PWM + Low RDS(on) MOSFETs design to support the 3rd Gen AMD Ryzen™ CPUs by offering incredible precision in delivering power to the motherboard's most power-hungry and energy-sensitive components as well as delivering enhanced system performance and ultimate hardware scalability.
GIGABYTE realize that customer won't stop chasing a better computing performance. We take care of it and implement on products. Adopting Daisy Chain, apply PCIe 4.0 components to get B550 motherboards ready to enter next generation and get upgrade.
Memory layout - daisy chain design
With the optimized daisy-chain routing, the B550 motherboard provides a proven speed of DDR4-4000MHz and beyond with high density memory modules. Optimized daisy-chained routing eliminates the stub effect, pushes the one DIMM per channel in dual channel interleaving mode to hit higher memory frequencies, providing professional gamers a denser and faster system memory experience.
Dual NVMe M.2 PCIe SSDs in RAID 0 Support
B550 AORUS motherboards offer the industry's best compatibility in terms of NVMe storage for users who demand high capacity and seek the best performance. AORUS' unique design can be configured in RAID for record speeds of up to 6560 MB/s (Sequential Read), making AORUS the obvious choice for the ultimate PC.
Advanced thermal solution
Unthrottled performance is guaranteed by the advanced thermal solution which including Heatsinks and Thermal Guards. B550 motherboards are cool on MOSFETs and M.2 SSDs even on full loading. It provides lower temperatures for users.
With durability in mind, GIGABYTE provides a thermal solution for M.2 SSD devices. The M.2 Thermal Guard prevents throttling and bottlenecks from high speed M.2 SSDs as it helps to dissipate heat before it becomes an issue.
Native USB 3.2 Gen 2
AMD B550 chipset provides native USB 3.2 Gen2 ports with speeds up to 10Gbps. Available over the USB Type-A connector, the USB3.2 Gen2 is much improved with twice the bandwidth compared to its previous generation as well as backwards compatibility with USB2.0 and USB3.2 Gen1.
Hi-Fi audio system
For enthusiasts, sound quality is just as essential to the gaming experience. B550 motherboards are equipped with high quality audio components to provide a superb audio experience. The exclusive AORUS AMP-UP Audio technology makes for the ideal onboard sound solution for the most demanding audiophiles.
High-end audio capacitors
GIGABYTE motherboards use high-end audio capacitors. These high quality capacitors help deliver high resolution and high fidelity audio to provide the most realistic sound effects for gamers.
Audio noise guard
GIGABYTE motherboards feature an audio noise guard that essentially separates the board’s sensitive analog audio components from potential noise pollution at the PCB level.
B550 motherboards feature RGB FUSION 2.0 and offer the option to control onboard, external light strips, and/or AORUS devices with RGB/ Addressable RGB LEDs to make your PC unique and stylish.
RGB Fusion 2.0
Now offering more LED customizations than ever, users can truly adapt their PC to represent their lifestyle. With full RGB support and a redesigned RGB Fusion 2.0 application, the user has complete control over the LEDs which surround the motherboard.
With an integrated intuitive user interface, the RGB Fusion 2.0 provides you a better solution for customizing the lighting effects across all supported devices. From motherboards, graphics cards to the peripheral products, you can personalize your gaming rig with your own style and show off your build by sharing the profiles. In addition, the new gaming mode makes the lighting effects interactive with selected games to bring you the most immersive gaming experience.
GIGABYTE is reputable for its product durability and high standard of manufactured process. Needless to say, we use the best, high quality components on B550 motherboards and reinforce each part of components to be solid and durable.
The innovative one piece stainless steel shielding design from GIGABYTE reinforces the PCIe connectors to provide the extra strength required to support heavy graphics cards.
Gigabyte BIOS & app center
Good software goes hand in hand with perfect hardware. B550 motherboards bundled several useful and intuitive software to help users to control every aspect of motherboard.
