Premium Power Design
Stable power is crucial for maximizing the performance of AMD processors. The motherboard is designed to meet the needs of high-core-count CPUs. It features 14(80A) + 2(80A) + 1(80A) power stages that integrate high-side and low-side MOSFETs and drivers into packages rated for up to 80A each. This configuration ensures optimal power delivery, efficiency, stability and performance for both current and future AMD processors.
Incredible DDR5 Performance
For those who want to fly past stock DDR5 speeds, this motherboard is primed and ready for enthusiast-grade kits, courtesy of vast AMD Extended Profiles for Overclocking (EXPO™) support. Seasoned veterans can further tweak performance via an extensive array of settings in the UEFI.
DRAM Overclocking Performance
Comprehensive memory tuning options are the cornerstone of TUF GAMING motherboards. With the motherboard, you can extract all the potential out of your DDR5 modules*, whether they’re from an extreme-speed kit or an entry-level set that would otherwise be locked.
ASUS AEMP
ASUS Enhanced Memory Profile (AEMP) is an exclusive firmware feature for PMIC-restricted memory modules. AEMP automatically detects the memory chips on your kit and then presents optimised frequency, timing and voltage profiles that you can quickly apply.
M.2 PCIe 5.0 Support
This motherboard also features one PCIe 5.0 M.2 slot to enjoy the fastest data transfers of up to 128 Gbps*, and all M.2 slots support NVMe RAID configurations to take advantage of the latest available speeds.
Impressive Thermal Management
AIO Pump Header
An integrated AIO management system enables full control of PWM or DC water pumps, making it perfect for custom or all-in-one cooling setups.
Enlarged VRM Heatsinks
The extensive surface area of this heatsink covers the MOSFETs and chokes to improve thermal performance.
Multiple Temperature Sources
Each header can dynamically reference three thermal sensors. Fan Xpert 4 allows you to map the temperature of supported ASUS graphics cards to optimize cooling for GPU- and CPU-intensive tasks.
Smart Fan Protection
A dedicated integrated circuit protects each fan header from excess heat and electrical currents.
M.2 Heatsinks
All three M.2 slots have dedicated heatsinks to help keep M.2 SSDs at optimal operating temperatures and ensure consistent performance and reliability.
Smart Fan Protect
A dedicated integrated circuit protects each fan header from excess heat and electrical currents.
4-Pin PWM/DC Fan
All onboard fan headers support auto-detection of PWM or DC fans.
PCIe 5.0 for Graphics Card?
PCIe 5.0 offers twice the data transfer speed of PCIe 4.0, making it robust enough to handle new data-heavy tasks. PCIe 5.0 also brings other benefits, such as electrical changes to improve signal integrity, backward-compatible CEM connectors for add-in cards and backward compatibility with previous versions of the PCIe bus.
Front USB 10Gbps Type-C®
This motherboard features a USB 10Gbps Type-C® front panel connector for speedy data transfers of up to 10Gbps.
Rear USB 20Gbps Type-C®
Extensive USB support ensures connections to a wide array of external devices. This motherboard includes a USB 20Gbps Type-C® port on the rear I/O panel that delivers transfer speeds of up to 20Gbps.
Easy PC DIY
PCIe Slot Q-Release
A physical lever unlocks the first PCIe slot’s security latch with one tap, greatly simplifying the process of detaching a PCIe card from the motherboard when it’s time to upgrade to a new GPU or other compatible device.
M.2 Q-Latch
The innovative ASUS Q-Latch makes it easy to install or remove an M.2 SSD without the need for specific tools or screws. This design employs a simple locking mechanism to secure the drive and neatly detach it with one tap.
Q-LED
The on-board Q-LED troubleshooting lights give PC builders a quick indicator to confirm that key components – CPU, RAM, graphics card, storage devices – are functioning normally during startup. It can also alert them when memory modules have not been properly installed–even before booting.
BIOS FlashBack™
BIOS FlashBack™ simplifies BIOS updates. Just load the BIOS file onto a FAT32 USB stick, insert it into the BIOS FlashBack™ port, and press a button—no CPU or memory needed.
Realtek 7.1 Channel Audio
This motherboard utilizes an audio codec designed in close collaboration with Realtek — the Realtek ALC1220P. It features an unprecedented 120 dB signal-to-noise (SNR) ratio for the stereo line out and a 113 dB SNR for the line in, providing pristine audio quality. Additionally, an impedance-sensing circuit automatically adjusts gain to ensure an optimal volume range for your headphones.
Outshine The Competition
ASUS Aura Sync offers synchronized lighting with other Aura Sync products, including motherboards, graphics cards, monitors and peripherals.
