4.3 Connexions de cable
The HCG750 Gold is a fully modular power supply, allowing you to connect only the cables your system requires. This helps improve airflow and reduce cable clutter.

This image shows a close-up of the modular cable ports on the power supply. Each port is clearly labeled for its intended connection type (M/B, PCI-E/CPU, SATA/Molex), simplifying the cable management process.
- 24-pin Motherboard Cable: Connect the 24-pin cable to the corresponding port on your motherboard and the PSU.
- EPS/CPU 8-pin Cable(s): Connect the 8-pin (4+4 pin) EPS/CPU cable(s) to your motherboard's CPU power connector(s) and the PSU. Modern motherboards may require one or two 8-pin connectors.
- PCI-E 6+2 pin Cable(s): Connect the 6+2 pin PCI-E cable(s) to your graphics card(s) and the PSU. Ensure all required power connectors on your graphics card are utilized.
- Cables SATA: Connecteu els cables d'alimentació SATA a les unitats d'emmagatzematge (SSD, HDD) i a les unitats òptiques.
- Cables Molex: Connect Molex cables to any peripherals that require them (e.g., older fans, fan controllers).
- FDD Cable (Optional): If your system requires a floppy disk drive power connector, use the FDD adapter.
Route cables neatly within your case to optimize airflow and aesthetics.
4.4 Encès inicial
- After all connections are secure, connect the AC power cord to the power supply and then to a wall outlet.
- Flip the main power switch on the back of the power supply to the "ON" (I) position.
- Power on your computer system.
5. Instruccions de funcionament
5.1 Hybrid Mode Operation

This image displays the rear of the power supply, featuring the AC power input, the main ON/OFF switch, and a small toggle switch labeled "HYBRID MODE".
The Antec HCG750 Gold features a Mode híbrid, controlled by a switch on the rear panel. This mode allows the 120mm FDB fan to remain off at low loads, providing absolute silence during light computing tasks. The fan will automatically activate when the power supply load increases to maintain optimal cooling.
- Hybrid Mode ON: The fan will not spin until a certain load or temperature threshold is reached, ensuring silent operation at low power consumption.
- Hybrid Mode OFF: The fan will spin continuously, adjusting its speed based on load and temperature. This provides consistent airflow through the PSU.
Choose the mode that best suits your preference for noise levels and cooling performance.
6. Manteniment
6.1 Neteja
- Regularly clean the exterior of the power supply and the fan intake/exhaust vents to prevent dust buildup.
- Use compressed air to gently remove dust from the fan blades and heatsinks. Ensure the system is powered off and unplugged before cleaning.
- Do not use liquid cleaners directly on the power supply.
6.2 Fan Inspection
- Periodically check the fan for any obstructions or unusual noises.
- If the fan is making excessive noise or not spinning when it should (outside of Hybrid Mode's silent operation), consult the troubleshooting section or contact support.
