How to use

To install the Chieftec GPB-350S power supply unit, ensure your computer system is disconnected from the electrical outlet and the old power unit has been safely removed. Mount the PS/2 form factor unit into the designated bay of your PC case and secure it with screws. Connect the 20+4 pin ATX connector to the motherboard and attach the necessary peripheral Molex cables to your internal components. Verify all connections are secure before restoring power to the system.

What to consider before purchase

  • Verify that your computer components require no more than 350 W of total power
  • Check that your local electrical grid supplies an AC input voltage between 200 and 240 V
  • Confirm your PC case has adequate space for a PS/2 form factor power supply unit
  • Ensure your motherboard utilizes a standard 20+4 pin ATX power connector

Usage recommendations: Always verify the power consumption of all internal PC components before installation to ensure the 350 W capacity is sufficient for your system requirements. Maintain clear airflow around the 12 cm cooling fan to support optimal thermal performance.
