Grow your dreams with AI magic
Driven by a passion for innovation and the pursuit of precision, we crafted the ROG Astral. Inspired by the universe’s wonders, it blends art and technology, achieving stellar cooling and unmated performance.

ARGB lighting allows for personalised setting.

Four axial tech fan design enhances airflow for optimal cooling.

Quad-Fan Force
A revolutionary four-fan design creates a powerful vertical airflow channel that boosts air pressure by up to 20%. This results in premium thermal performance that dramatically lowers GPU temperatures and minimises hotspots, enabling unprecedented clock speeds.
The addition of a fourth fan permits more densely packed heatsink fins, increasing cooling potential.
A patented Vapour chamber designed with milled pathways allows heatpipes to sink in without flattening, boosting heat dissipation efficiency. This innovative combo maximises contact surface and improves thermal performance by over 10%.
MaxContact is an ASUS-exclusive manufacturing technique that effectively increases the surface area of the GPU heat spreader by 5% for improved thermal efficiency.
By melting to effectively fill the gaps between the GPU and the thermal module, a premium phase-change GPU thermal pad provides superior thermal conductivity and enhanced heat dissipation, ensuring optimal performance and longevity for graphics cards under heavy loads.
Premium Power Delivery
Powerful 80-amp MOSFETs deliver over 35% more headroom than the standard design. This helps ensure enhanced performance, stability and higher overclocking potential.
ASUS GPU Guard & Bracket
ASUS GPU Guard applies adhesive to secure all four corners to reduce the risk of cracks, while a GPU bracket helps ensure uniform mounting pressure and extra stability.
Protective PCB Coating
A protective conformal coating envelops the circuit board to help protect against short-circuits caused by moisture, dust or debris.
Auto−Extreme Technology
An automated manufacturing process that sets new standards in the industry by allowing all soldering to be completed in a single pass, ASUS Auto-Extreme technology reduces thermal strain on components and avoids the use of harsh cleaning chemicals, resulting in less environmental impact, lower manufacturing power consumption and a more reliable product overall.
Ultra Rigid Metal Case
A high-quality diecast frame, shroud, and backplate tightly brace the PCB for rigidity, and a 304 stainless steel I/O bracket plus bundled graphics card holder ensures stable mounting.
GPU Tweak III: Effortless GPU Monitoring and Tuning
Effortless Overclocking
GPU Tweak Ill lets you effortlessly fine-tune overclocking settings to achieve peak performance. It includes OC mode & Silent mode toggles, an OC scanner and a Voltage-Frequency Tuner for precise adjustments.
Thermal Map
Embedded sensors across the VRMs, chokes and VRAM collect data for the Thermal Map, empowering you to check real-time temperatures in each area and to easily adjust system settings for optimised performance.
Power Detector+
Power Detector+ can detect anomalies across any of the six power pins from the 12VHPWR cable. If a fault is detected, you are immediately notified that the power cable needs to be reseated.
Mileage
The Mileage feature tracks usage at different power levels, so you can keep an eye on what kind of load you have used across multiple game sessions.

Two PWM FanConnect headers provide additional DIY flexibility. Chassis fans can be directly synced with the card and tuned with a curve that is based on CPU and GPU temperatures, delivering extra intake or exhaust for demanding 3D tasks.

Do you prioritise low core temps or low noise levels? Performance mode lets the fans spin up to keep the card running cool all the time and Quiet mode keeps the same power target and top-end settings while offering a less aggressive fan curve for quieter operation at medium temperatures.

Patented “GPU-First” Intelligent Voltage Stabiliser
Pair with the ROG Thor III and ROG Strix Platinum Series PSU and enjoy reliable power for your graphics card. GPU-First enhances voltage stability by up to 45%, even during demanding gaming sessions and overclocking scenarios, helping to ensure peak performance for a more consistent gaming experience. Additionally, the integration of a GaN MOSFET boosts power efficiency by up to 30%.
Aura Sync
With indirect Aura ARGB lighting, the ROG Astral GeForce RTX 5080 provides endless possibilities for personalisation with colour or functional effects. Use it with other Aura components to create a uniquely coordinated build.
