ASUS RTX 4090 ROG Matrix Graphics Card PCB Detailed

During Computex 2023, ASUS unveiled its latest GeForce RTX 4090 ROG Matrix graphics card, touting it as the most formidable RTX 4090 design to date. Equipped with an integrated water cooling system of a 360mm specification, ASUS declares that this new product has a default power consumption of 550W, which can be amplified to a maximum of 600W, boasting the highest overclocking frequency among all RTX 4090 graphics cards.

The GeForce RTX 4090 ROG Matrix graphics card employs a seamless metal frame, with a thickness of 2.5 slots. Its aesthetically pleasing shell boasts RGB lighting effects, and the board lacks any fans. The card’s tail-end features a metal brace providing support for the liquid pipe connections and integrates a liquid metal thermal module, with all cooling facilitated by an integrated water-cooling solution. It pairs with the ROG MF-12 ARGB series fan, utilizing a magnetically attached linkage. Der8auer had the opportunity to dismantle the aforementioned components and photograph the GeForce RTX 4090 ROG Matrix graphics card’s PCB board without any coverings.

This marks the first time it has been wholly exposed to players. In fact, in some design aspects, this graphics card bears a strong resemblance to the ROG Strix series, as both adopt a 24-phase power supply scheme. According to ASUS, the GeForce RTX 4090 ROG Matrix graphics card has new temperature sensors placed around the GPU chip and power modules. Paired with corresponding firmware, it can identify potential hotspots caused by uneven thermal pad installations. Furthermore, ASUS has opted to replace Onsemi with MPS components, though both have a current of 70A.

Der8auer expressed that the GeForce RTX 4090 ROG Matrix graphics card “noticeably reduced coil whine,” an enhancement in design that is likely to be appreciated by a section of players. It’s understood that the ROG Strix series will undergo similar modifications, as ASUS has changed some component suppliers.
