Advanced Cooling for High-End Systems

Keep Your Components Cool In order to guarantee un-throttled performance Aorus have opted for an advanced thermal solution, including a huge stacked fin heatsink, direct touch heatpipes, thermal guards meaning the B550 Master is capable of keeping the MOSFETs and M.2 SSDs cool and comfortable even under maximum load. Whether you\'re a gamer, builder or just an enthusiast you can expect lower temperatures and higher performance from the B550 Master.

1. Direct Touch HeatpipesHeatpipe directly touches the heating source VRM components that guarantee good contact between VRM and heatsink.

2. Thermal Base PlateAddition of a thermal baseplate to increase thermal dissipation and motherboard longevity to provide a strong building foundation.

3. LAIRD 7.5 W/mK Thermal PadUsing LAIRD 7.5 W/mK high thermal conductivity pads, it can transfer 4x more heat when compared to traditional thermal pads in same time.

4. Fins-Array HeatsinkUsing a stacked-fin heatsink increases surface area by 300% and can provide atleast 30% lower temperatures on the MOSFETs.

5. 3X M.2 Thermal GuardEnlarged M.2 thermal guard heatsink helps the high-speed, large capacity of PCIe 4.0/3.0 SSDs to prevent overheat throttling and performance bottlenecks.

Intricate Design for Expert Performance

16 Phase Digital Power DesignIn order to fully support 3rd Generation AMD Ryzen CPUs, the B550 Master comes equipped with the most complete power solution yet, with true direct, digital and multiple power phases, birthed from countless experiments, testing and tinkering the B550 AOROUS MASTER is built using a pure digital CPU power design which includes a digital controller and a total of 16 phases for Vcore and SOC and is capable of providing 70A from each phase and with additional 8+4 solid-pin connectors offering incredibly precise power delivery to even the most power hungry components. The B550 AORUS MASTER will enable you to get the most out of your 3rd Generation Ryzen CPU

Handle Demanding Tasks with Ease

2X COPPER PCBGIGABYTE\'s exclusive 2X Copper PCBs design provides sufficient power trace paths between components to handle greater than normal power loads and to remove heat from the critical CPU power delivery area. This is essential to ensure the motherboard is able to handle the increased power loading that is necessary when overclocking.

Excel your Memory for Strong Performance

Support for DDR4 XMP Up to 5400MHz and BeyondAORUS is offering a tested and proven platform that ensures proper compatibility with profiles up to 5400MHz and beyond. All users need to do to attain this performance boost is to ensure that their memory module is XMP capable and that the XMP function is activated and enabled on their AORUS motherboard. Please see the complete validated memory support list. Product features may vary by model.

Next Generation Connectivity

Wi-Fi 6 & Blueooth 5 ModuleIntel Wireless solution supports 802.11ax, enables gigabit wireless performance, provides smooth video streaming, better gaming experience, few dropped connections and speeds up to 2.4Gbps*. Moreover, Bluetooth 5 provides 4X range over BT 4.2 and with faster transmission.

Illuminate your PC with Beautiful Colour

RGB FUSION 2.0Now offering more LED customizations than ever before, users can truly adapt their PC to represent their lifestyle. With full RGB support and a redesigned RGB Fusion 2.0 application, you have complete control over the LEDs which surround the motherboard.

Immerse yourself into any Environment

Hi-Res AudioThis impressive motherboard is Hi-Res Audio certified, meaning that it is capable of reproducing frequencies up to 40kHz or above which ensures user with the best audio quality at all times.

ESS SABRE reference DAC ES9118 Never worry about your heavy graphics card damaging your motherboard again. AORUS’ proprietary Ultra Durable PCIe Metal Shielding reinforces the PCIe connector to prevent slot damage due to heavy graphics card. The DIMM and PCIe metal shield also provides extra strength for when you forget to release the lock while replacing your component, adding a foolproof option which can save your PC’s life.

Durability for Years to Come

Industry Leading Ultra Durable™ PCIe ArmourThe innovative one piece stainless steel shielding design from GIGABYTE reinforces the PCIe connectors to provide the extra strength required to support heavy graphics cards.
