The power supply is sometimes misunderstood as one of the main components that every computer requires to run. When shopping for power supplies, sometimes we don't understand exactly how important it actually is and tend to not give it some serious thought and even sometimes grab the least powerful/costly unit that we see. This is a very bad idea because the power supply regulates and protects all your other components, and when getting the cheaper units, they tend to die and most times they don't go out alone.
