disconnect all power cables from the existing system before you add a device.
Before connecting or removing signal cables from the motherboard, ensure that all
power cables are unplugged.
Seek professional assistance before using an adapter or extension cord. These devices
could interrupt the grounding circuit.
Ensure that your power supply is set to the correct voltage in your area. If you are not
