Utilize liquid metal’s remarkable thermal efficiency on the ASUS Graphics Card die for unprecedented performance. This 4090 graphics card has an unusual production technique that firmly confines the liquid to the die area, allowing it to be mounted in any orientation.



All of the heat-producing components on the PCB are covered by the full-coverage copper cold plate, which makes it possible for the radiator to disperse heat without the need for an additional fan effectively and produces a quieter operation.



A strong, specially designed pump tuned for water flow will supply enough coolant to the radiator via 700 mm tubing, maximizing die cooling and maintaining the ROG Matrix GeForce RTX 4090 at maximum performance.


Three premium fans work with an extra-thick 360 mm radiator to provide superior heat dissipation.


Installation and cable management are made simple by the magnetic connector that connects the daisy-chainable fans and transfers power and control signals.


The ROG Matrix offers countless opportunities for customization with color and functional effects thanks to its indirect Aura ARGB illumination. To create a build that is exclusively yours, synchronize the glow and pair it with various compatible system components.


Plus, two PWM Fan Connect headers mean more DIY customization options. For intense 3D applications, chassis fans can be directly mounted to the card and adjusted using a curve based on CPU and GPU temperatures, providing additional intake or exhaust.


AutoExtreme Technology

With its automated production technique, Auto-Extreme Technology, all soldering may be done in a single pass, setting new industry standards. This results in less of an impact on the environment, reduced manufacturing power usage, and an all-around more reliable product by lowering the temperature strain on components and avoiding the need for harsh cleaning chemicals.


Additional stability is added to the crucial die-to-heat-spreader link by an ASUS Graphics Card bracket. The stainless steel rear I/O bracket offers a more robust mount and helps ward off corrosion in humid environments. For the Axial-tech fans, a conveniently located Dual Bios switch enables fast switching between “performance” and “quiet” speed profiles.

Graphics Card Installation

  1. After ensuring that your computer is disconnected from the power supply, take off the chassis cover to reveal an accessible motherboard PCIe slot.
  2. Take off the covers over the chassis’ rear expansion slots based on what your Asus graphic card requires.
  3. When you hear a click, insert the Asus card into the motherboard’s PCIe slot.
  4. Use the necessary screws to fasten the Asus GPU to the chassis.
  5. Use the PCIe power connectors from the power supply unit (PSU) to connect to the graphics cards if it has any auxiliary power connectors. Please be sure to click the graphic card Asus and PSU using the supplementary power adapter cable, if your card has one.
  6. Ensure that the graphics card and display device are connected.

Warning! Please connect the power to each Asus GPU using a different PCIe cable. A PCIe splitter cable may become damaged if both ends are used.


Linking Together Display Units

Connect your display device to the graphics card using any appropriate wire.


Installing drivers

  1. Go to to access the ASUS support website.
