- Check that the power switch on the back of the PSU is in the 'ON' (I) position.
- Verify that the wall outlet is functional by testing it with another device.
- Confirm all internal power cables (24-pin ATX, CPU, PCIe, SATA) are firmly connected.
- System Instability/Random Shutdowns:
- Ensure the power supply's wattage (750W) is sufficient for all your system components.
- Check for overheating. Ensure proper ventilation and clean any dust from the PSU fan and case.
- Verify all power connections are secure.
