Empower the ultimate performance
C621 AORUS XTREME motherboard uses an all IR digital CPU power design which includes both a digital PWM Controller and PowlRstage, and is capable of providing at least 50A of power from each phase, for a total of 1600A.
These 100% digital controller and optimized 2 * 8+8 solid-pin CPU power connectors offer incredible high efficiency and precision in delivering power to the platform's most power-hungry and energy-sensitive components, allowing enthusiasts to get the absolute maximum performance from the W-3175X processor.
Transient Optimization
High efficiency compensating POSCAPs placement optimizes total transient response of the VRM delivering power to the most power-hungry and energy-sensitive W-3175X processor.
Power Up Synchronization on Dual PSU
Optimized power path design of 2 * 8+8 solid-pin CPU power connectors eliminates voltage and current race conditions from two different power supply units.
Dual ATX_24 solid-pin platform power connectors offer incredible precision in synchronization between two independent power supply units activation.
The power of silent flow
Full aluminum high precision CNC manufactured to optimize the flow direction in the chassis provides the most reliable and silent thermal solution for the system.
Seeds of your creativity
Max out the 48 lanes from W-3175X with the 7-slot design and the additional 4 lanes from the PCH that make C621 AORUS XTREME the ultimate power house of content creation.

Dual High Speed INTEL Gigabit LAN

Intel® GbE LAN features cFosSpeed, a network traffic management application which helps to improve network latency and maintain low ping times to deliver better responsiveness in crowded LAN environments.

Ultra Durable PCIe Armor
Never worry about your heavy graphics card damaging your motherboard again. AORUS proprietary Ultra Durable PCIe Metal Shielding + Double Locking Bracket reinforces the PCIe connector to prevent slot damage due to heavy graphics cards.
Ultra Durable Solid Pin Power Connectors
Solid Pin Power Connectors Advantages
  1. Larger contact area for electricity
  2. More metal quantity to sustain higher power and generated heat
  3. Ultra durable and longer lifespan
Ultra Durable Anti-Sulfur Design
Sulfur compounds in the air can penetrate tiny onboard resistors creating chemical changes and causing these resistors to open or short. If either of these occurs, the motherboard will fail to function. By equipping resistors with an Anti-Sulfur Design, GIGABYTE gives Ultra Durable Motherboards a whole new meaning.
Static-Electricity & Surge Protection
GIGABYTE motherboards use ICs with up to 3 times the ESD resistance levels compared to traditional ICs. This helps to better protect the motherboard and its components against potential damage caused by static electricity. GIGABYTE motherboards also feature special anti-surge ICs that protect your motherboard and your PC from any surge in power delivery that may occur, ensuring that your PC is equipped to deal with any potentially irregular and inconsistent power delivery.
More Ultra Durable Design
Durable Black™ Solid Caps
For extended periods, even in extreme performance configurations.
2x Copper PCB 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.
GIGABYTE Patented DualBIOS™ Design
DualBIOS™, an exclusive technology from GIGABYTE that protects arguably one of your PC's most crucial components, the BIOS. GIGABYTE DualBIOS™ means that your motherboard has both a 'Main BIOS' and a 'Backup BIOS', protecting users from BIOS failure due to virus, hardware malfunction, improper OC settings or power failure during the update process.
