3.2. Component Installation
Before installing components, lay the chassis on its side on a stable, non-abrasive surface. Remove the tempered glass side panel by unscrewing the four thumbscrews.
- Motherboard: Install the I/O shield into the rear opening. Align your ATX, micro-ATX, mini-ITX, or E-ATX motherboard with the standoffs and secure it with screws.
- Power Supply (PSU): The PSU mounts at the bottom rear of the case. Slide your PSU into the dedicated compartment and secure it with screws from the rear.
- Storage Drives: Utilize the included HDD trays for 3.5-inch drives and dedicated SSD brackets for 2.5-inch drives. Mount them in their respective locations within the chassis.
- Graphics Card (GPU): Install your graphics card into the appropriate PCIe slot on your motherboard. The case supports GPUs up to 420mm in length.
- CPU Cooler: Ensure your CPU cooler height does not exceed 160mm.

3.3. Cable Management
The P400A offers 25mm of cable management space behind the motherboard tray. Utilize the integrated Velcro straps and tie-down points to route and secure cables neatly. This improves airflow and maintains a clean aesthetic visible through the tempered glass panel.
3.4. Connecting Peripherals
Connect your monitor, keyboard, mouse, and other peripherals to the appropriate ports on your motherboard's I/O shield and the case's front I/O panel.

4. Operating Instructions
4.1. Power On/Off
Press the power button located on the top-front I/O panel to turn your system on or off. A short press will typically power on, while a longer press (usually 4-5 seconds) will force a shutdown.
4.2. Digital-RGB Control
The Phanteks Eclipse P400A Digital comes with an integrated Digital-RGB controller. Use the dedicated buttons on the top I/O panel to cycle through various lighting modes and colors for the pre-installed fans. For advanced customization and synchronization with other D-RGB products or your motherboard, connect the D-RGB cable to a compatible 3-pin 5V addressable RGB header on your motherboard and use the motherboard's software (e.g., ASUS Aura Sync, MSI Mystic Light Sync, Gigabyte RGB Fusion).
5. Maintenance
5.1. Cleaning
Regular cleaning helps maintain optimal airflow and extends the lifespan of your components. Use a soft, dry cloth to wipe down exterior surfaces. For the tempered glass panel, a glass cleaner can be used, applied to the cloth first, not directly to the glass.
5.2. Dust Filters
The P400A features removable dust filters on the front mesh panel, top, and bottom (for the PSU intake). Periodically remove and clean these filters by rinsing them with water and allowing them to dry completely before reinstallation. This prevents dust buildup inside the chassis.
6. Troubleshooting
- System Not Powering On:
- Ensure the PSU is properly connected to the wall outlet and the power switch on the PSU is in the 'On' position.
- Verify that the front panel power switch cable is correctly connected to the motherboard's F_PANEL header.
- Check all internal power connections (24-pin ATX, 8-pin CPU, PCIe for GPU).
- Fans Not Spinning/RGB Not Lighting Up:
- Confirm that the fan power cables are securely connected to the motherboard fan headers or a fan controller.
- Ensure the Digital-RGB cables are properly connected to the integrated controller or the motherboard's 3-pin 5V D-RGB header.
- If using motherboard software for RGB, ensure the software is installed and configured correctly.
- Poor Airflow/High Temperatures:
- Clean all dust filters and ensure they are not obstructed.
- Verify that all case fans are spinning in the correct direction (intake/exhaust).
- Improve cable management to reduce airflow obstruction.
