3. Configuration et installation
3.1 Préparation du châssis
Before installing components, ensure the chassis is placed on a stable, flat surface. The Evolv Shift XT features an open chassis design, allowing access to all internal components by opening the hinged panels.
3.2 Installation de la carte mère
The chassis supports Mini-ITX motherboards. Carefully align your motherboard with the standoffs and secure it using the provided screws.
3.3 Installation du GPU
The Evolv Shift XT includes a built-in PCI-e x16 Gen4 Riser Cable. Install your graphics card into the riser cable slot. The chassis supports GPUs up to 324mm in length and 3 slots wide. Ensure the GPU is securely mounted using the Riser Cable Lock and any additional GPU straps.

3.4 Installation de l'alimentation électrique
This chassis requires an SFX power supply. Mount the power supply in its designated internal location. Route power cables using the integrated cable hooks and Velcro ties for optimal organization and airflow.
3.5 Configuration du système de refroidissement
The chassis offers three cooling configurations:
- Mode compact : Standard height, suitable for CPU air coolers up to 72mm tall.
- Mode Air Boost : Chassis height extended by 32mm, allowing for installation of two 120mm or 140mm fans at the top for enhanced airflow.
- Mode de refroidissement liquide : Chassis height extended by 60mm, enabling installation of a 240mm AIO liquid cooler at the top. The removable radiator bracket assists with installation.

4. Mode d'emploi
4.1 Adjusting Chassis Height
To change between Compact, Air Boost, and Liquid Cooled modes, carefully extend or retract the top section of the chassis. Ensure all internal cables and components have sufficient clearance during adjustment.
4.2 Contrôle de l'éclairage D-RGB
The integrated D-RGB Infinity Mirror features built-in lighting effects. These can be controlled directly via the chassis's front I/O panel or synchronized with compatible motherboard software if connected to the motherboard's D-RGB header. No additional software is required for basic control.
4.3 Ports d'E/S avant
The front panel provides a USB-C Gen2 port (10Gb/s) and a USB 3.0 port for connecting peripherals and external storage devices.

5. Entretien
To ensure optimal performance and longevity of your Phanteks Evolv Shift XT chassis, regular maintenance is recommended:
- Nettoyage extérieur : Use a soft, dry cloth to wipe down the anodized aluminum panels. Avoid abrasive cleaners.
- Élimination de la poussière : Periodically clean the ultra-fine mesh panels and internal components to prevent dust buildup, which can hinder airflow and cooling efficiency. Compressed air can be used for this purpose.
- Gestion des câbles: Regularly check cable routing to ensure no cables are obstructing airflow or fan operation.
6. Dépannage
Cette section aborde les problèmes courants que vous pourriez rencontrer :
- Températures élevées des composants : Ensure the chassis is configured to the appropriate cooling mode (Air Boost or Liquid Cooled) for your components. Verify that all fans are operating correctly and that mesh panels are clear of obstructions. Proper cable management is crucial for airflow in SFF builds.
- Difficulty Installing Components: Due to the compact nature of SFF cases, precise component selection and careful planning are necessary. Refer to the specifications for maximum GPU length, CPU cooler height, and AIO radiator support.
- Power Cable Interference: In some configurations, especially with water cooling, GPU power cables might interfere with water lines or fans. Consider using 90-degree power adapters if space is extremely limited.
- D-RGB Lighting Not Functioning: Check all D-RGB connections. If connected to a motherboard, ensure the motherboard's RGB software is correctly configured. If using built-in controls, verify the front I/O connections.
