How do Dell power supplies work?

A Dell power supply ensures that your computer has power and is working properly. The power supply gives you the ability to power on your computer. The Dell power supply is one of the most essential parts of a computer, because without it, your computer would not work at all. This article will show you what a power supply is and how they work.

Function

The power supply inside of a computer converts AC power from the wall outlet to lower voltage DC power that a computer can use. It delivers electricity in such a form that it can be used by the motherboard and by every other part of a computer. The electrical outlet in a home delivers power at 230 volts. If electricity were delivered at 230 volts to a computer, it would fry the components immediately. The power supply uses a switching technology that converts higher voltage into three different types of voltages.

Identification

You can find the power supply from the outside of a computer by looking at the place where you plug in the power cord. If you open a computer, the Dell power supply is very easily found. The power supply is housed in a metal box and usually located at the back of the computer. The power supply also has an opening for the computer fan and switch, and you will see a bundle of wires emerging from the front of it.

How does it work?

When you press the "Power" button on a computer, it sends a signal to the power supply to start the flow of power to the components inside the computer, such as Dell motherboards. Even when the computer is turned off, there is still enough power running to allow the power button to work when pressed.

Warning

If you look inside a computer power supply, you will find diodes, transistors, capacitors and transformers, along with a heat sink and fan. The main capacitor located in the Dell ac adapter supplies power and holds a charge long after the computer has been powered off and unplugged. For this reason, you should never open a power supply yourself to try to repair it.
