Do you want to know How to check Power Supply Unit wattage so you are on the right place

A power supply turns alternating current (AC) into direct current, which is a steady source of power that computer parts need (DC). While some hardware parts, like an SSD, are optional, the power supply is not. Without it, the rest of the hardware inside the computer would not work.

Power supply is often written as PSU, which stands for “power supply unit.” The different sizes of motherboards, cases, and power supplies are called “form factors.” For these three parts to work, they must fit together well.

Back of the case or chassis is where the power supply is. You’ll see that the computer’s power cord, which is plugged into the wall, plugs into the back of the power supply.

Most people only see the power supply from the back. It also has a hole at the back for a fan that sends air to the back of the computer case.

On the side of the power supply that faces the outside of the case, there is a male connection with three prongs that accepts a power cord. The other prong goes straight into a power outlet.It may also have a power switch and a red voltage switch on very low-level sources.

From the source inside the PC, a large number of cables reach out. The connectors on the other ends of the cables send power to different parts of the computer.Some connectors only work with the motherboard, while others work with hard drives, optical drives, graphics cards, and so on.

Watts are used to measure how much power your computer’s power supply can give it. Each part of the computer needs a certain amount of power to work right, so it’s important to have a power supply unit (PSU) that can give that amount.
