Parts of a Power Supply. Ideally, a DC Power Supply Unit (commonly called a PSU) deriving power from the AC mains (line) supply performs a number of tasks: 1. It changes (in most cases reduces) the level of supply to a value suitable for driving the load circuit. 2. It produces a DC supply from the mains (or line) supply AC sine wave. 3. It Identify the Connectors of the Power Supply - CCM PC power supply cables contain vital connectors for your computer. There are many connectors, and identifying them can be difficult, especially for a novice. Here is a quick guide that will help you to identify the different types of connectors of your PC's power supply. 26.1 Power Supply Characteristics :: Chapter 26. … Ideally, a power supply accepts AC power, possibly noisy or outside specifications, and turns that AC power into smooth, stable DC power with no artifacts. In fact, no power supply meets the ideal, but good power supplies come much closer than cheap ones. Processors, memory, and other system components are designed to operate with pure, stable DC voltage. Any departure from that may reduce How to Figure Out What Power Supply You Need for … Peak power is the maximum power that the power supply can provide for a short time, and it is called peak surge power.
