A developer known as LevinAI has released an experimental tool designed to bypass power limits on NVIDIA RTX 50-series mobile GPUs. The software allows users to increase power consumption beyond the standard OEM-defined thresholds, with reports suggesting it can push an RTX 5090 mobile GPU to 225W.
The utility functions by modifying low-level NVIDIA power policy values that are typically inaccessible to end-users. To operate the tool, users must disable Windows driver signature verification. The developer notes that the software only supports Blackwell-based GPUs and may not function on all laptop models or brands.
The project is partially AI-generated, and the developer has updated the tool from version 1.5.0 to 1.8.0. While some users on platforms like Reddit have criticized the code structure and the reliance on AI, others have reported successful performance gains in benchmarks such as 3DMark.
The author warns that the tool is experimental and carries potential risks to hardware. OEM power limits are originally set to protect cooling systems and power delivery components from damage. Users are advised that attempting to override these settings could lead to hardware failure.
