A developer's fully vibe-coded utility appears to work, letting some GeForce RTX 50-series laptops raise power limits by up to 28% — the RTX 5090 mobile GPU reaching 225W.
A developer has built a fully vibe-coded utility that appears to work as intended, giving owners of some GeForce RTX 50-series laptops a way to raise their machines' GPU power limits by as much as 28%. The tool, described in a report by Tom's Hardware, was produced through AI-assisted coding rather than conventional development — yet it seemingly delivers the headline capability its creator set out to build.
The most striking result involves the flagship mobile part: the tool can juice an RTX 5090 laptop GPU to 225W. Power limits define the maximum wattage a mobile GPU is permitted to draw, and raising that ceiling can allow a chip to sustain higher clocks for longer under load. A 28% uplift over a laptop's factory-configured limit is a substantial bump for a closed, thermally constrained system such as a notebook.
The vibe-coded label is notable in its own right. The code was not hand-crafted line by line; it emerged from AI-driven tooling, and per the report the result still seems to function for its intended purpose. For a consumer-facing tweak to low-level GPU behavior, that is an unusual provenance, and it shows how quickly AI coding tools are being turned toward enthusiast utilities that interact directly with hardware settings.
Caveats remain. The report describes the tool as working on some RTX 50-series laptops rather than across the board, and frames its results as seemingly effective rather than independently verified. Buyers evaluating high-end mobile GPUs — whether for gaming or for local AI workloads — should treat the 225W RTX 5090 figure as what one enthusiast-built tool can achieve on compatible hardware, not as a universal upgrade path.
