4. Istruzioni per l'uso
4.1 Accensione
Press the power button located on the front I/O panel to turn on your computer.
4.2 Controllo dell'illuminazione ARGB
The DS900 supports Addressable RGB (ARGB) lighting. If your motherboard has a 5V 3-pin ARGB header, you can connect the case's ARGB cables to it and control the lighting effects via your motherboard's RGB software (e.g., ASUS Aura Sync, MSI Mystic Light Sync, Gigabyte RGB Fusion, ASRock Polychrome Sync). If your motherboard does not have an ARGB header, an external ARGB controller (not included) may be required for lighting control.
4.3 Porte I/O frontali
Il pannello I/O frontale fornisce un comodo accesso a:
- 1x porta USB 3.0
- 2 porte USB 2.0
- Audio HD (jack per cuffie e microfono)
- Pulsante di accensione
- Pulsante di reset
5. Manutenzione
Una manutenzione regolare aiuta a garantire prestazioni ottimali e longevità dei componenti del PC.
5.1 Filtri antipolvere
The DS900 is equipped with removable dust filters on the top and bottom. Periodically remove and clean these filters to prevent dust buildup inside the case, which can hinder airflow and component cooling.
- Estrarre delicatamente i filtri.
- Clean them with a soft brush or rinse with water (ensure they are completely dry before reinstallation).
5.2 Tempered Glass Panels
Clean the tempered glass panels with a microfiber cloth and a non-abrasive glass cleaner. Avoid harsh chemicals that could damage the glass or coatings.
5.3 Pulizia degli interni
Occasionally, use compressed air to blow out dust from inside the case, especially around fans, heatsinks, and other components. Ensure the system is powered off and unplugged before cleaning.
6. Risoluzione Dei Problemi
Ecco alcuni problemi comuni e possibili soluzioni:
- Il PC non si accende:
- Check if the PSU is properly connected to the wall outlet and switched on.
- Ensure all power cables (24-pin ATX, 8-pin CPU, PCIe power) are securely connected to the motherboard and components.
- Verificare che il cavo dell'interruttore di alimentazione del pannello frontale sia collegato correttamente al connettore della scheda madre.
- Fans are not spinning:
- Check if fan cables are securely connected to the motherboard fan headers or a fan controller.
- Ensure the PSU is providing power.
- ARGB lighting is not working:
- Verify the ARGB cable is correctly connected to a 5V 3-pin ARGB header on your motherboard (not a 12V 4-pin RGB header).
- Ensure your motherboard's RGB software is installed and configured correctly.
- If using an external controller, check its power and connections.
- USB ports not functioning:
- Check if the front panel USB 3.0 and USB 2.0 cables are correctly connected to their respective headers on the motherboard.
