Secure and Verify Power Supply Unit Connections

Follow these steps to ensure secure power delivery to your motherboard and components:

1. Safety First: Power off the PC and flip the PSU rear I/O switch to the 'O' (off) position. Unplug the power cable from the wall outlet and the PSU.
2. Inspect Cables: Remove the side panel of your PC case. Locate the 24-pin ATX connector on the right side of the motherboard and the 4/8-pin CPU power connector near the top left.
3. Reseat Connections: Firmly press each connector into its socket until you hear or feel a mechanical click, ensuring the locking tabs are fully engaged.
4. Verify Switch: Ensure the PSU rear I/O switch is toggled to the 'I' position (on).
5. Testing: Reconnect the power cable to the wall and the PSU, then attempt to power on the system to verify that the connection was the source of the intermittent failure.

Required Tools: Non-conductive workspace, adequate lighting, and potentially a screwdriver if access is restricted by case shrouds.
