Power Supply - CS1


Power supply

Before you start touching the power supply, please refer to the health and safety at the top of this page.

This is pretty much self explanatory; you need a power supply that will supply your computer with the power that it needs to run. The power supply is located at the back of a computer case, it is fairly easy to replace or insert a different one if need be.

What you need to do is you need to first of all unscrew it, (because it needs to be secured into place), then it should just slide out, then you will need to disconnect all of the other wires that are going to the motherboard, slide the new one in (making sure you have the right size power supply is vital so measure the old one before purchasing or getting a new one, I know I’ve made this mistake), screw It back into place then simply just plug the wires back into the motherboard, it is as simple as that.

Also in a power supply you have a thing called AC and DC, these stand for Alternate current and Direct current. This is the form of which the electricity is transferred through the power pack. Alternate current (AC), is where the electricity current can go in any direction, meaning it can go back and forward if it wishes too. AC is better to use for transferring electricity to long distances, that’s why most power sockets you will find in a home uses AC. DC is different though. DC means direct current, which is where the current is sent directly to the point of which it is needed. DC is less reliable than AC because it doesn’t travel long distances.
