04 PSU The fourth part of your computer building journey will be installing the power supply. We are also going to start putting the parts inside the case starting with the Power Supply Unit (PSU). In this section, we will take a detailed look at the PSU, and learn about its function.

Let’s talk about the PSU
Case
Power Supply
If you build your computer without including this part, all you have is computer parts in a plastic case that does absolutely nothing. The PSU powers every part of your computer! Because it is so vital, you want to make sure that it is strong enough to power all the parts that you decide to put into your build. The PSU also has its own cooling system with a built-in fan, and sometimes they have RGB color options. But, unlike the other parts we have installed so far, the power supply gets screwed directly into the case.
