Dynamic Power Plan

A Windows system tray application that automatically switches power plans and Lian Li fan configurations based on CPU/GPU usage or running applications.

Features

• Automatic Power Plan Switching: Monitors CPU and GPU usage and switches between power plans when thresholds are exceeded
• Multi-GPU Support: Detects and monitors NVIDIA, AMD, and Intel GPUs automatically
• Lian Li Fan Control: Integrates with L-Connect 3 to switch fan profiles
• Game Detection: Watches for specific executables and triggers boost mode automatically
• System Tray Interface: Clean tray icon with right-click menu for manual control
• Configurable Thresholds: Customize CPU/GPU thresholds, hold times, and watched games
• Start with Windows: Option to run automatically at Windows startup
• Admin Elevation: Automatically requests admin rights for power plan changes

Quick Start

Option 1: Download Pre-built Release

1. Download the latest release from GitHub Releases
2. Extract the ZIP to a folder of your choice (e.g., your Dropbox folder for portability)
3. Double-click DynamicPowerPlan.exe
4. Click "Yes" on the UAC prompt (admin rights required)
5. The tray icon appears - you're done!

Option 2: Run from Source

1. Install Python 3.11+ from python.org
2. Clone or download this repository
3. Install dependencies:

   pip install -r requirements.txt

4. Run the application (as Administrator):

   python main.py

Configuration

Edit config.json to customize the application. The file is located in the same folder as the executable.

Example Configuration

{
  "plans": {
    "normal": "Everyday",
    "boost": "High Performance"
  },
  "thresholds": {
    "cpuPercent": 70,
    "gpuPercent": 70,
    "promoteHoldSeconds": 5,
    "demoteHoldSeconds": 15
  },
  "sampling": {
    "intervalMs": 1000
  },
  "games": {
    "watch": [
      "cod.exe",
      "bf2042.exe",
      "fortniteclient-win64-shipping.exe"
    ]
  },
  "gpu": {
    "nvidia": {
      "preferSMI": true,
      "smiPath": "C:\\Windows\\System32\\nvidia-smi.exe"
    },
    "amd": {
      "preferPyadl": true
    }
  },
  "lconnect": {
    "enableFanBoost": true,
    "serviceName": "LConnectService",
    "targetFile": "C:\\ProgramData\\Lian-Li\\L-Connect 3\\settings\\L-Connect-Service",
    "mbOnDir": ".\\MB_on",
    "mbOffDir": ".\\MB_off"
  }
}

Configuration Options

Setting	Description	Default
plans.normal	Name of your normal/everyday power plan	"Everyday"
plans.boost	Name of your high performance power plan	"High Performance"
thresholds.cpuPercent	CPU usage threshold to trigger boost mode	70
thresholds.gpuPercent	GPU usage threshold to trigger boost mode	70
thresholds.promoteHoldSeconds	Seconds of sustained high usage before switching to boost	5
thresholds.demoteHoldSeconds	Seconds of sustained low usage before switching back to normal	15
sampling.intervalMs	How often to check CPU/GPU usage (milliseconds)	1000
games.watch	List of executable names that trigger boost mode when running	[]
gpu.nvidia.preferSMI	Use nvidia-smi for NVIDIA GPU monitoring	true
gpu.nvidia.smiPath	Path to nvidia-smi.exe	System default
gpu.amd.preferPyadl	Use pyadl library for AMD GPU monitoring	true
lconnect.enableFanBoost	Enable Lian Li fan profile switching	true

System Tray Menu

Right-click the tray icon to access:

• Status Display: Current CPU/GPU usage and mode (Boost/Normal)
• High Performance: Manually switch to boost mode
• Everyday (Normal): Manually switch to normal mode
• Auto: Return to automatic switching based on usage
• Start with Windows: Toggle auto-start at Windows boot
• Open Config File: Edit configuration in your default editor
• Exit: Close the application

How It Works

1. The app monitors CPU and GPU usage at regular intervals (default: 1 second)
2. When usage exceeds the threshold for the "promote hold time", it:
   • Switches to the "High Performance" power plan via powercfg
   • Copies the MB_on fan configuration to L-Connect 3 (full-speed fans)
3. When usage drops below the threshold for the "demote hold time", it:
   • Switches back to the "Everyday" power plan
   • Copies the MB_off fan configuration (normal fans)
4. If a watched game executable is detected running, boost mode is triggered immediately

Requirements

• Windows 10/11
• Administrator rights (for power plan switching)
• Lian Li L-Connect 3 (optional, for fan control features)

GPU Monitoring Support

The application automatically detects and monitors GPUs from multiple vendors:

GPU Vendor	Primary Method	Fallback Method
NVIDIA	nvidia-smi command	GPUtil library
AMD	pyadl library	Windows Performance Counters
Intel	Windows Performance Counters	-

Notes:

• NVIDIA: Install the NVIDIA driver (nvidia-smi is included)
• AMD: Supported out of the box
• Intel: Works automatically on Windows 10/11
• Multi-GPU: Returns maximum utilization across all detected GPUs

Power Plan Setup

The app expects power plans named "Everyday" and "High Performance" by default. To check your available power plans:

powercfg /list

You can change the plan names in config.json to match your existing plans.

Building from Source

To create a standalone executable:

1. Install Python 3.11+ and dependencies:

   pip install -r requirements.txt
   pip install pyinstaller

2. Build the executable:

   pyinstaller --clean DynamicPowerPlan.spec

3. Find the executable in the dist folder

Troubleshooting

App doesn't start

• Make sure you're running as Administrator
• Check that Python dependencies are installed (if running from source)

Power plan doesn't change

• Verify the power plan names in config.json match your system (powercfg /list)
• Ensure you clicked "Yes" on the UAC prompt

GPU not detected

• NVIDIA: Install the latest NVIDIA driver
• AMD: Supported out of the box
• Check the logs folder for error messages

L-Connect fan profiles not working

• Verify L-Connect 3 is installed
• Check the target path in config.json matches your L-Connect installation
• The MB_on and MB_off folders must contain valid L-Connect-Service files
