Setup and Installation
Follow these steps to install your PowerSpec 650W Power Supply into your computer system:
- Prepare Your System:
- Turn off your computer and unplug the AC power cord from the wall outlet.
- Open your computer case.
- If replacing an existing PSU, disconnect all cables from the old power supply and remove it from the case.
- Ensure you are grounded to prevent electrostatic discharge (ESD) damage to components.
- Mount the Power Supply:
- Carefully slide the PowerSpec PSU into the designated power supply bay in your computer case.
- Align the screw holes on the PSU with those on the case.
- Secure the PSU using the provided mounting screws.

- Main Power (20+4-pin): Connect the 20+4-pin ATX cable to the motherboard's main power connector. Ensure both sections are securely latched.
- ATX 12V (4+4-pin): Connect the 4+4-pin CPU power cable to your motherboard's CPU power connector. Some motherboards may require only 4 pins, while others require all 8. Ensure correct orientation.
- PCI-E (6+2-pin): Connect the 6+2-pin PCI-E cables to your graphics card(s). Modern graphics cards often require one or more 6-pin or 8-pin connectors.
- SATA Connectors: Use SATA cables to power storage devices such as SSDs, HDDs, and optical drives.
- Molex Connectors: Connect Molex cables to older peripherals or case fans that require this type of power.
- Floppy Connector: If needed, connect the floppy power cable to compatible devices.
Note: Ensure all connectors are fully seated and latched. Improperly connected cables can lead to system instability or component damage. Pay close attention to the main motherboard power connector and CPU power connector as they are crucial for system boot-up.
- Cable Management: Route cables neatly within your case to improve airflow and aesthetics. Utilize cable ties or case features for organization.
- Close Case and Power On:
- Once all connections are secure, close your computer case.
- Plug the AC power cord into the power supply and then into a wall outlet or surge protector.
- Flip the power switch on the back of the PSU to the "ON" position (usually marked with "I").
- Power on your computer.
Operating Instructions
