4. Configuration et installation
Liste de contrôle avant l'installation
- Ensure your computer case is compatible with ATX PSUs.
- Verify that your motherboard and other components require 850W or less power.
- Gather necessary tools: screwdriver, zip ties (for cable management).
Étapes d'installation
- Préparez votre système : Disconnect the computer from the power outlet. Open your computer case to access the PSU mounting area. If replacing an old PSU, remove it first.
- Monter le bloc d'alimentation : Carefully slide the KOLINK Regulator PSU into the designated PSU bay in your computer case. Ensure the fan is oriented correctly (typically facing downwards or inwards, depending on case design). Secure the PSU with the provided mounting screws from the rear of the case.
- Raccordez les câbles modulaires : Identify the necessary cables for your components. Connect the modular cables to the corresponding ports on the PSU first, then route them to your components. Refer to the labels on the PSU for correct port identification.
- Alimentation de la carte mère : Connectez le câble ATX 24 broches à votre carte mère.
- Puissance du processeur : Connect the 4+4 pin CPU cable(s) to your motherboard's CPU power connector(s).
- Alimentation PCIe : For graphics cards, use the 6+2 pin PCIe cables. For modern GPUs requiring 12VHPWR, use the dedicated 12VHPWR 600W cable. Ensure all connectors are fully seated.
- Alimentation SATA : Connectez les câbles d'alimentation SATA à vos SSD, HDD et lecteurs optiques.
- Alimentation périphérique : Use peripheral (Molex) cables for any other components requiring them.
- Gestion des câbles: Route cables neatly to improve airflow and aesthetics. Use zip ties or cable straps to secure them.
- Affaire close : Une fois toutes les connexions sécurisées et vérifiées, fermez le boîtier de votre ordinateur.

5. Mode d'emploi
- Branchez l'alimentation CA : Plug the provided AC power cord into the PSU's power inlet and then into a wall outlet or surge protector.
- Alimentation sous tension : Locate the power switch on the rear of the PSU (next to the AC inlet) and flip it to the 'I' (On) position.
- Allumer l'ordinateur : Appuyez sur le bouton d'alimentation de votre ordinateur pour démarrer votre système.
Semi-Fanless Mode Operation
The KOLINK Regulator PSU features a semi-fanless mode. This means the 120mm FDB fan will remain off or spin at very low RPMs during low system loads to minimize noise. As the system load increases and the internal temperature rises, the fan will automatically activate and adjust its speed to maintain optimal cooling. This operation is normal and contributes to a quieter computing experience.
6. Entretien
Proper maintenance ensures the longevity and optimal performance of your PSU.
- Gardez les évents dégagés : Ensure that the PSU's intake and exhaust vents are not obstructed by dust, cables, or other objects. Good airflow is crucial for cooling.
- Nettoyage de la poussière : Periodically clean dust from the PSU's exterior and fan grille using compressed air. N'ouvrez pas le bloc d'alimentation casing.
- Conditions environnementales : Operate the PSU within recommended temperature and humidity ranges. Avoid extreme conditions.
7. Dépannage
If you encounter issues with your KOLINK Regulator PSU, refer to the following common problems and solutions:
| Problème | Cause possible | Solution |
|---|---|---|
| Le système ne s’allume pas. | PSU power switch off, AC cable loose, faulty wall outlet. | Ensure PSU switch is 'On'. Check AC power cable connection. Test wall outlet with another device. Verify all modular cables are securely connected. |
| Le système s'allume mais s'éteint inopinément. | Overload, overheating, loose connections, component fault. | Assurez-vous que le système total soittage does not exceed 850W. Check for proper airflow. Verify all modular cables are fully seated. If problem persists, test components individually. |
| Le ventilateur du bloc d'alimentation ne tourne pas. | Semi-fanless mode active, low system load. | This is normal operation in semi-fanless mode. The fan will activate under higher loads. If the fan never spins even under heavy load, contact support. |
| Bruit inhabituel provenant du bloc d'alimentation. | Loose screws, fan obstruction, coil whine. | Check PSU mounting screws. Ensure no cables or debris are obstructing the fan. Minor coil whine can be normal; if excessive, contact support. |
If troubleshooting steps do not resolve the issue, please contact KOLINK customer support.
