5.1. Important Considerations for Cable Connections
Some users have reported variations in SATA connector spacing compared to original Dell power supplies. If you are connecting multiple hard drives side-by-side, you may find the spacing between the SATA power connectors on this unit to be shorter (approximately 1.5 inches) than on some original Dell PSUs (which might be around 5.5 inches). This could potentially make it challenging to power two closely mounted drives without an extension cable or modification. Additionally, ensure the SATA connectors are oriented correctly; some users have noted that the slot orientation might differ from original units, requiring careful alignment or a slight twist of the cable.
6. Mode d'emploi
Once properly installed, the ARLBA 300W Power Supply operates automatically with your computer system.
- Mise sous tension : After installation, connect the computer's power cord to a wall outlet and press the system's power button. The power supply will provide power to all connected components.
- Éteindre: Shut down your computer through the operating system. The power supply will cease operation when the system is off.

7. Entretien
The ARLBA 300W Power Supply is designed for minimal maintenance.
- Nettoyage: Periodically, with the computer powered off and unplugged, use compressed air to gently clear dust from the power supply's fan and vents. Do not use liquid cleaners.
