Premium power delivery and maximum system stability
Stable power is key to achieving maximum performance from AMD processors, which is why the motherboard is equipped with 14 (80A) + 2 (80A) + 1 (80A) power stages with integrated high-side and low-side MOSFETs and drivers rated for up to 80 amps. This configuration ensures optimal efficiency, stability, and performance for current and future AMD processors. An eight-layer PCB design improves heat dissipation from the voltage regulators, thereby enhancing system stability and allowing for better overclocking. ProCool (8+8 pin) power connectors provide a more solid connection to the power supply and, with their lower impedance, minimise hotspots and the risk of failure. TUF components, including military-grade chokes and TUF 5K black metallic capacitors, guarantee high durability, 52% higher temperature tolerance, and a 2.5× longer lifespan than standard capacitors. Digi+ VRM Control, one of the industry's finest voltage-regulator modules, ensures precise voltage regulation, delivering smooth, clean power to the CPU under all conditions.
Memory and storage for maximum speed and overclocking
TUF GAMING motherboards offer comprehensive memory tuning options that unlock the full potential of DDR5 modules, whether they are extreme-speed kits or entry-level modules with limited overclocking. With support for AMD Extended Profiles for Overclocking (EXPO™), the board can surpass standard DDR5 memory speeds, while experienced users can further fine-tune performance through the extended settings in the UEFI. The exclusive ASUS Enhanced Memory Profile (AEMP) feature automatically detects memory chips and offers optimised frequency, timing, and voltage profiles for an easy performance boost. The board is also equipped with a PCIe 5.0 M.2 slot with transfer speeds of up to 128Gb/s, and all M.2 slots support NVMe RAID configurations to harness the highest possible storage speeds.
PCIe 5.0, high-speed USB, and cooling for modern builds
The PCIe 5.0 interface delivers double the data transfer speed of PCIe 4.0, providing enough throughput for modern graphics cards and demanding, data-heavy tasks. It also offers electrical enhancements for better signal integrity, backward-compatible CEM connectors, and full compatibility with previous PCIe versions. Aggregated bandwidth reaches up to 512Gb/s with PCIe 5.0 x16. The motherboard also provides extensive connectivity via a rear 20Gb/s USB Type-C® port with transfer speeds of up to 20Gb/s and a front 10Gb/s USB Type-C® port that enables fast data transfers of up to 10Gb/s. To ensure stable performance and optimal system cooling, ASUS AIO coolers are available, offering high cooling performance, overclocking potential, a bold design, and customisable features for modern TUF Gaming motherboards, allowing you to create the ultimate gaming rig.
Easy disconnection and connection
A physical lever unlocks the security latch of the first PCIe slot with a single touch, which significantly simplifies the process of disconnecting a PCIe card from the motherboard when it's time to upgrade to a new graphics card or other compatible device. With Q-Antenna, connecting a Wi-Fi antenna to your PC is quick and easy.
Quick installation and diagnostics
The innovative ASUS Q-Latch system makes it easy to install or remove an M.2 SSD without any special tools or screws. This solution uses a simple locking mechanism to secure the drive, and a single click neatly disconnects it. Built-in Q-LED troubleshooting indicators give PC builders a quick reference to confirm that key components – the CPU, RAM, graphics card, or storage devices – are functioning normally during startup. It can also alert them to incorrectly installed memory modules – even before booting the system.
TUF durability – Stainless steel protection and military-grade reliability
TUF Gaming motherboards feature a stainless steel rear I/O panel, which is corrosion-resistant and offers up to 3× longer lifespan. These models have passed a demanding 72-hour salt fog test, surpassing the industry standard. TUF LANGuard then provides military-grade protection with advanced signal-coupling technology and high-quality capacitors that improve network throughput and protect the motherboard from static electricity and surges caused by lightning. BIOS FlashBack™ allows you to update the BIOS without a CPU or memory.
Strength, reliability, and system security
SafeSlot with metal reinforcement ensures firm graphics card installation and maximum transfer speeds, while SafeDIMM protects memory modules and allows for their quick and reliable installation. ESD Guards use special TVS diodes that provide protection against electrostatic discharges of up to ±10kV in air and ±6kV on contact, significantly exceeding industry standards. TUF LANGuard then provides military-grade protection with advanced signal-coupling technology and high-quality capacitors that improve network throughput and protect the motherboard from static electricity and surges caused by lightning.
2.5Gb Ethernet for maximum speed and stability
The integrated 2.5Gb Ethernet improves your LAN connection, increasing bandwidth speeds by up to 2.5×. Using your existing LAN cable, you can take advantage of this network upgrade for reduced latency, smoother high-resolution video playback, and faster file transfers.
Realtek ALC1220P and DTS® for a clear and immersive audio experience
This motherboard uses a sound codec designed in close collaboration with Realtek – the Realtek ALC1220P. It features an unprecedented signal-to-noise ratio (SNR) of 120dB for the stereo line-out and 113dB SNR for the line-in, guaranteeing pristine audio quality. In addition, an impedance-sensing circuit automatically adjusts the gain to ensure an optimal volume range for your headphones. DTS® Audio Processing enhances the sound from gaming headsets and speakers by reducing distortion and providing deeper bass, making games, films, and music sound better. It also allows you to customise your audio settings.
Addressable Gen 2 RGB headers
Three addressable Gen 2 RGB headers support up to 500 LEDs on Gen 2 RGB devices and allow Aura Sync to automatically customise lighting effects across your entire PC build. The headers also offer full backward compatibility with existing Aura Sync devices.
Outshine the competition
The TUF GAMING motherboard features edge lighting that accentuates its rugged design. ASUS Aura offers complete RGB control with presets for integrated LEDs and third-party strips. You can synchronise all of this with an ever-expanding portfolio of Aura-compatible hardware.
