Here's the first picture of the bare PCB of the upcoming ASUS ROG MATRIX GeForce RTX 4090 graphics card, courtesy of der8auer, who was given access to the card as part of a G.Skill overclocking event. We spotted a fully assembled version of this card on the Computex floor earlier. The PCB is essentially of the same design as the ROG Strix RTX 4090, but with some major changes. The card draws power from a single 16-pin 12VHPWR connector, and we're hearing that the card's power limits will be the highest ever allowed by NVIDIA for any custom RTX 4090, perhaps even getting close to the 600 W continuous design limit of the connector.

The card features a 24-phase VRM for the GPU power phases, and a 4-phase VRM for the 24 GB of GDDR6X memory across a 384-bit memory interface. We cannot make out the exact DrMOS components for this VRM, but der8auer says these are 70 A-rated MPS-sourced DrMOS (the ROG Strix uses 70 A DrMOS sourced from OnSemi). Although one can't tell just by looking, ASUS says that it has deployed a network of SMD thermal sensors across the critical areas of the card, such as individual rows of memory chips, or DrMOS. This is essentially ASUS's inspiration of the late EVGA iCX. There is a physical dual-BIOS switch, some consolidated voltage measurement points, and some fan and lighting headers, but that's about it.
