3. Setup and Installation
Before beginning installation, ensure your computer system is powered off and unplugged from the wall outlet. Always handle components with care and refer to your PC case and motherboard manuals for specific installation guidelines.
Installation Steps:
- Mount the PSU: Secure the NZXT C650 PSU into the designated power supply bay of your PC case using the provided screws. Ensure the fan is oriented correctly for optimal airflow (typically facing downwards or upwards, depending on case design).
- Connect Modular Cables: Identify the necessary cables for your motherboard (24-pin ATX, 8-pin CPU), graphics card(s) (PCIe), and peripherals (SATA, Molex). Connect these cables to the corresponding modular ports on the PSU.
- Route Cables: Route the connected cables through your case's cable management channels to their respective components. This helps improve airflow and aesthetics.
- Connect to Components: Plug the 24-pin ATX cable into your motherboard, the 8-pin CPU cable into the CPU power header, and PCIe cables into your graphics card(s). Connect SATA and Molex cables to your storage drives and other peripherals.
- Secure Connections: Ensure all cable connections are firmly seated to prevent power delivery issues.
- Power On: Once all connections are secure, plug the AC power cord into the PSU and a wall outlet. Flip the power switch on the back of the PSU to the 'ON' position. You can now power on your computer system.

4. Operation
The NZXT C650 PSU is designed for efficient and quiet operation. Its 80 Plus Gold certification ensures high power efficiency, reducing wasted energy and heat generation. The optimized circuit design and low thermal dissipation contribute to its silent performance, even under load.
The micro-controller (MCU) enabled protection mechanism continuously monitors current, voltage, and output wattage, providing stable and safe power delivery to your components. This intelligent monitoring helps prevent damage from power fluctuations.
5. Maintenance
Proper maintenance can extend the lifespan of your power supply and ensure optimal performance.
- Dust Removal: Periodically clean dust from the PSU's fan and ventilation grilles using compressed air. Ensure the system is powered off and unplugged before cleaning.
- Airflow: Ensure your PC case has adequate airflow to prevent heat buildup around the PSU. Avoid blocking the PSU's intake or exhaust vents.
- Cable Management: Maintain tidy cable management to prevent cables from obstructing airflow within the case.
