ASUS Announces ROG MATRIX RTX 4090 Flagship Graphics Card

ASUS at the 2023 Computex launched the ROG MATRIX GeForce RTX 4090, its absolute top-end custom-design graphics card, designed to be the fastest money can buy. The card features the industry's highest factory-overclock for an RTX 4090, and has its power limits set squarely at 600 W, maxing out the single 16-pin 12VHPWR connector. The card also features the strongest VRM solution ever by ASUS for a graphics card, to hold this PL. The star attraction with this card is that it is marketed as the first graphics card that incorporates liquid metal technology.

What it essentially means, is that the cooling solution uses liquid-metal thermal interface material (TIM) for the GPU. The enthusiasts among you know how difficult it is to apply and maintain liquid metal, and ASUS is among the first companies to do this on an industrial scale, using a fully automated process. The company originally designed this mechanized liquid-metal TIM application technique for its high-end notebooks, but figured it could use it even for graphics cards. Liquid-metal TIMs offer the highest possible thermal conductivity as the TIM is pure metal. It's also electrically conductive, which is why application and maintenance is extremely difficult. ASUS innovated a cold-plate design specifically for this task, so the graphics card could survive international shipping from its factories. A third innovation by ASUS has been to develop a special multi-layer resin that protects the SMD components on the PCB against being shorted by the liquid-metal. ASUS is so confident in its liquid-metal technology, that the company is backing this graphics card with a comprehensive 5-year warranty.
