PowerTools
A Steam Deck plugin for advanced power management, enabling CPU/GPU frequency control, SMT toggling, and battery charge capping.
What is PowerTools?
PowerTools is a plugin for the Steam Deck that enables advanced power management and system tweaks. It allows users to control CPU and GPU frequencies, toggle SMT, set power limits, and manage battery charging behavior directly from the Decky Plugin Loader interface. The plugin solves the need for granular performance customization on the handheld device without requiring command-line expertise.
Steam Deck power users and enthusiasts who want to fine-tune system performance, optimize battery life, or experiment with hardware limits beyond the default SteamOS settings.
Developers choose PowerTools because it provides a safe, user-friendly interface for low-level system controls that are otherwise inaccessible, with persistent per-game settings and active community support through the Decky ecosystem.

Use Cases
Best For
- Overclocking or underclocking the Steam Deck CPU/GPU for performance or efficiency
- Disabling SMT to improve compatibility with certain games
- Capping battery charge rate to prolong battery lifespan
- Monitoring detailed battery information and health metrics
- Applying different power profiles for specific games or applications
- Experimenting with system limits for benchmarking or thermal testing
Not Ideal For
- Casual Steam Deck users who are content with default SteamOS performance sliders and avoid system tweaks
- Developers or users on other handheld PCs or Linux systems without Decky Plugin Loader compatibility
- Scenarios where system stability and official vendor support are critical, as power tweaks can introduce instability
Pros & Cons
Pros
Enables precise tuning of CPU threads, SMT, and frequencies, allowing users to optimize for specific games or tasks, as highlighted in the README's key features.
Offers battery charge rate capping and detailed info display, helping prolong battery lifespan, which is a unique advantage over default SteamOS settings.
Saves settings in JSON files per game, making profiles persistent between restarts, as specified in the README for easy management.
Integrates with Decky Plugin Loader to provide a graphical interface for low-level tweaks, bridging the gap from command-line access.
Cons
Requires Decky Plugin Loader for installation, adding an extra layer of setup and potential points of failure compared to standalone tools.
Building from source necessitates a Rust toolchain and npm, as per the README, which can be daunting for non-technical users.
Incorrect power settings, such as overclocking or disabling SMT, could lead to crashes or hardware issues, requiring careful experimentation.
