Adapter Mod Lets RTX 5090 Draw Up to 750W Through a Single Cable

Renowned overclocker Der8auer has showcased an unusual experiment with the flagship ASUS ROG Matrix GeForce RTX 5090. He managed to bypass the system's power limit, making the graphics accelerator draw up to 750W through a single 12V-2x6 connector. All modifications were reversible and required no physical alteration to the video card itself.

The ASUS ROG Matrix RTX 5090 is originally designed to operate in two power configurations. To activate the high-performance 800W BIOS, it requires simultaneous connection of both a standard power cable and a special BTF connector on the motherboard. If only the cable is used, power is capped at 600W.

Der8auer discovered that the card detects the BTF connection via specific pins in the adapter itself. During his experiment, he modified the included BTF adapter by installing jumpers between several pins. This tricked the card's protection system into believing both power sources were active, even when the motherboard's BTF connector was not in use.

After the modification, monitoring software showed an average power draw of around 700W, with peaks reaching up to 750W. A key feature of this method is its reversibility, as all changes are made only to the adapter, which can easily be restored to its original state. The video card itself remains untouched, preserving its warranty and full functionality.

The overclocker himself emphasizes that this is a purely research project, demonstrating the platform's capabilities. He strongly advises against replicating this mod for daily use due to the significant risks of overheating and damage to the power delivery components. The experiment clearly illustrates how enthusiasts are finding unconventional ways to unlock the potential of the new GPU generation.
