A proper power cord should have copper wires of the correct rating. Some cheap imports also use wires that are rated for a lower power usage and these wires tend to burn out quickly.

The wires used in such cheap power cords cannot cope up with the load of power traversing through them. In case you have any doubts about the type of power cord you require, it is recommended that you take along your old power cord to the store where you intend purchasing the new one.

If you have observed carefully, the power cord has its ratings printed in fine letters along the protective coating. This information will help the store keeper to provide you with a new power cord whose ratings matches with your old power cord.

All reputed brand power cords use materials and connectors that conform to the original manufacturer’s specifications. Using them ensures that you can enjoy a risk free computing experience.
