How to assemble an ATX power supply for a computer

Power Supply is the part that supplies power to the devices inside the computer. The power supply is usually located at the back of the computer and has a fan to cool the internal components. Power supplies are usually built to a standard so they can fit into any case, with the exception of some power supplies that are made specifically for the movement.

Here are the steps to assemble an ATX power supply for a computer

Open the case side cover (Case) by tightening the rear screws and sliding the case cover back or up depending on the case. (Each case can be opened differently)
