© 2008, Laureate Higher Education Group, Inc. - 1 - Computer Hardware Tour Video Have you ever wondered what’s inside a personal computer? From the outside, PCs seem to come in a variety of sizes, but the shape of the case doesn’t have too much to do with what’s inside. Modern PCs are very modular. When your system is first built, you can select components that have higher or lower performance and cost. Later on, you can easily swap many of the parts for newer ones. This way you can gain additional capacity, speed, or features without having to buy a whole new computer. Most of the parts inside your computer need DC power of 3.3, 5, or 12 volts. A power supply is bolted to one corner of the case. It converts your AC wall current and delivers DC power through a series of standardized connectors. Most power supplies have extra connectors so you can add new components later on. You’ll notice that the power supply has a fan to circulate air and keep the system from overheating.
