Configuració i instal·lació
- Prepareu el vostre sistema: Ensure your computer case is compatible with ATX power supplies. Disconnect all power from your existing system.
- Muntar la font d'alimentació: Secure the DA750R Gold into the designated PSU bay of your computer case using the provided mounting screws. Ensure the fan is oriented correctly for optimal airflow (typically facing down if there's a bottom vent, or up if not).
- Connecteu els cables modulars: Identify the necessary cables for your motherboard, CPU, graphics card(s), and storage devices. Refer to Figure 3 for the modular connector panel layout.
- Placa base: Connect the 24-pin ATX cable to the MB 24 PIN port on the PSU and to your motherboard.
- CPU: Connect the 8-pin (4+4 pin) EPS cable(s) to the EPS port(s) on the PSU and to your motherboard's CPU power connector(s).
- Targeta gràfica (GPU): For modern GPUs, use the 12V-2x6 PCIe Gen5 cable. Connect it to the 12V-2x6 port on the PSU and to your graphics card. For older GPUs, use the standard 6+2 pin PCIe cables.
- Storage/Peripherals: Connect SATA and peripheral (Molex) cables to the SATA / PERIPHERAL ports on the PSU and to your hard drives, SSDs, and other devices.
- Gestió de cables: Utilize the flat design of the modular cables for easier routing and improved airflow within your case.
- Connecteu l'alimentació de CA: Once all internal connections are secure, connect the AC power cord to the PSU's AC inlet and then to a wall outlet or surge protector.

Instruccions de funcionament
- Encès: After connecting all cables, ensure the main power switch on the rear of the PSU (refer to Figure 4) is in the 'ON' position. Then, power on your computer system.
- ECO Mode (Semi-Fanless Operation): The DA750R Gold features an ECO mode switch on the rear panel.
- When the ECO switch is 'ON', the PSU fan will remain off under low load conditions, providing silent operation. The fan will automatically activate when the load increases or internal temperature rises.
- When the ECO switch is 'OFF', the PSU fan will operate continuously, regardless of load, providing maximum cooling at all times.
- Apagar: To shut down your system, perform a proper software shutdown through your operating system. For complete power disconnection, switch the main power switch on the PSU to the 'OFF' position and unplug the AC power cord.
Manteniment
- Neteja: Periodically clean the exterior of the power supply and its fan grill using a soft, dry cloth. For deeper cleaning, use compressed air to remove dust from the fan and internal components, ensuring the system is powered off and unplugged.
- Inspecció del cable: Comproveu regularment totes les connexions dels cables modulars per assegurar-vos que estiguin ben col·locades.
- Medi ambient: Maintain a clean, dust-free, and well-ventilated environment for your computer system to ensure optimal PSU performance and longevity.
Resolució de problemes
Sense poder
- Assegureu-vos que el cable d'alimentació de CA estigui connectat correctament tant a la font d'alimentació com a la presa de corrent.
- Verify the main power switch on the PSU's rear panel is in the 'ON' position.
- Check all modular cable connections (24-pin ATX, EPS, PCIe) to ensure they are fully seated.
- Proveu la presa de corrent amb un altre dispositiu per confirmar que tingui corrent.
- If possible, test the PSU with a PSU tester or in another known working system.
System Instability / Random Shutdowns
- Ensure the PSU is adequately rated for your system's total power consumption, especially under load.
- Check for proper ventilation around the PSU and within the case to prevent overheating.
- Verify that all power connectors to components (motherboard, CPU, GPU) are correctly installed.
- Consider updating motherboard BIOS and graphics card drivers.
Fan Not Spinning (in ECO Mode)
- This is normal behavior when the ECO switch is 'ON' and the system load is low. The fan will activate automatically when needed.
- If you prefer continuous fan operation, switch the ECO mode to 'OFF' on the rear panel.
