How to use

Install the CORSAIR CX power supply into a compatible PC case, securing it with the case mounting points and connecting the supplied cables to the motherboard, CPU power, GPU (if applicable), storage devices and peripherals according to the system requirements. Ensure correct orientation of the fan and clear airflow paths inside the case. Power on the system and verify stable operation and expected voltages in BIOS or with monitoring software.

Recommendations

For quieter operation, allow sufficient airflow in the case and avoid obstructing the 120mm fan. Use the power supply within its rated load range and check compatibility with your components before installation.
