WITH THE INCREDIBLE SUM OF ITS PARTS
The ROG Strix GeForce RTX 4090 brings a whole new meaning to going with the flow. Inside and out, every element of the card gives the monstrous GPU headroom to breathe freely and achieve ultimate performance. The unleashed reign of the NVIDIA Ada Lovelace architecture is here.
Axial-tech Upgrades: A Fresh Spin
Bigger and better. Axial-tech fans spin on dual-ball bearings and have been scaled up to propel 23% more air through the card, setting the stage for lower temperatures, less noise, and higher performance.
Reverse Rotation and 0dB Technology: Orchestrated Chill
The two side fans spin counterclockwise to minimize turbulence and maximize air dispersion through the heatsink. All three fans come to a standstill when GPU temps are below 50 Celsius, letting you play less-demanding games or perform light tasks in relative silence. Fans start up again when temps are over 55 C, referencing a speed curve that balances performance and acoustics for work or play.
3.5-slot Design: Through Thick and Fin
The custom sink is generously sized and structured to soak up heat from the GeForce RTX 4090 GPU so that it can be efficiently whisked away by the three Axial-tech fans.
Patented Vapor Chamber: Phase Changer
A vapor chamber featuring milled pathways lets the heatpipes sink in without being pressed flat, allowing heat to be carried more efficiently to the fin stack. In comparison to conventional vapor chamber and heatpipe combos, this potent pairing reduces GPU temperature by up to 5 Celsius when subjected to a 500W thermal load.
Premium Power Delivery: 1st Responder
Digital power control, an array of high-current power stages, and a lineup of 15K caps ensure massive reserves to reliably push performance boundaries.
Compact PCB: Packs a Punch
Component and trace layouts have been optimized onto a short PCB to reduce power losses and let heat escape through a massive backplate vent.
Metal Exoskeleton: Ultra-rigid
A high-quality diecast frame, shroud, and backplate tightly brace the PCB and strategically steer airflow.
GO WITH THE FLOW
It all comes together to effortlessly drive GeForce RTX 4090 performance to the max.
FanConnect II: Hook up
Two PWM FanConnect headers provide additional DIY flexibility. Chassis fans can be directly attached to the card and tuned with a curve that is based on CPU and GPU temperatures, delivering extra intake or exhaust for demanding 3D tasks.
Reinforcements: Additional Perks
A GPU bracket provides extra stability to the critical connection between die and heat spreader. The rear I/O bracket is made from stainless steel to prevent corrosion in humid climates and provide a more resilient mount. A conveniently placed Dual Bios switch allows quick selection between “performance” and “quiet” speed profiles for the Axial-tech fans.
Power Sensing: Quick Diagnosis
Know if your PSU is worthy. ROG Strix GeForce RTX 4090 graphics cards feature a high-speed circuit that constantly monitors input power from the PSU and utilizes conveniently placed LEDs to indicate voltage regulation issues and cable connection problems.
Reliability Boost
Auto-Extreme Technology is an automated manufacturing process that sets new standards in the industry by allowing all soldering to be completed in a single pass. This 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.
Symphony of Light
Aura-compatible ARGB lighting elements on the shroud and rightmost perimeter of the card provide endless possibilities for personalization with color or functional effects. Pair up with a vast range of compatible system components and coordinate the glow to create a build that’s uniquely you.
Pillar of Support
The bundled graphics card holder banishes sag and also contains a screwdriver to help you build.
GPU Tweak III
ASUS GPU Tweak III is more intuitive and feature-rich than ever before. A revamped interface offers greater accessibility by integrating core functions into a centralized dashboard, and our Voltage-Frequency tuner has been overhauled to make overclocking even easier. Additional goodies like 0dB fan technology, automatic profile swapping, a fully customizable on-screen display, and logging capabilities ensure that you get the most out of your graphics card.
