+# OPTIONAL: Setting NVIDIA GPU Power Limit at System Startup
+
+## Overview
+
+This guide explains how to set the power limit for NVIDIA GPUs at system startup using a systemd service. This ensures the power limit setting is persistent across reboots.
+
+## Steps
+
+### 1. Create and Configure the Service File
+
+1. Open a terminal and create a new systemd service file:
+
+    ```bash
+    sudo nano /etc/systemd/system/nvidia-power-limit.service
+    ```
+
+2. Add the following content to the file, replacing `270` with the desired power limit (e.g., 270 watts for your GPUs):
+
+    - For Dual GPU Setup:
+
+    ```ini
+    [Unit]
+    Description=Set NVIDIA GPU Power Limit
+
+    [Service]
+    Type=oneshot
+    ExecStart=/usr/bin/nvidia-smi -i 0 -pl 270
+    ExecStart=/usr/bin/nvidia-smi -i 1 -pl 270
+
+    [Install]
+    WantedBy=multi-user.target
+    ```
+
+    - For Quad GPU Setup:
+
+    ```ini
+    [Unit]
+    Description=Set NVIDIA GPU Power Limit
+
+    [Service]
+    Type=oneshot
+    ExecStart=/usr/bin/nvidia-smi -i 0 -pl 270
+    ExecStart=/usr/bin/nvidia-smi -i 1 -pl 270
+    ExecStart=/usr/bin/nvidia-smi -i 2 -pl 270
+    ExecStart=/usr/bin/nvidia-smi -i 3 -pl 270
+
+    [Install]
+    WantedBy=multi-user.target
+    ```
+
+    Save and close the file.
+
+### 2. Apply and Enable the Service
+
+1. Reload the systemd manager configuration:
+
+    ```bash
+    sudo systemctl daemon-reload
+    ```
+
+2. Enable the service to ensure it runs at startup:
+
+    ```bash
+    sudo systemctl enable nvidia-power-limit.service
+    ```
+
+### 3. (Optional) Start the Service Immediately
+
+To apply the power limit immediately without rebooting:
+
+```bash
+sudo systemctl start nvidia-power-limit.service
+```
+
+## Verification
+
+Check the power limits using `nvidia-smi`:
+
+```bash
+nvidia-smi -q -d POWER
+```
+
+Look for the "Power Management" section to verify the new power limits.
+
+By following this guide, you can ensure that your NVIDIA GPUs have a power limit set at every system startup, providing consistent and controlled power usage for your GPUs.
