Some common examples of power connectors include the 24-pin ATX main power connector, which provides power to the motherboard; the 8-pin (EPS12V/ATX12V) CPU power connector that supplies power to the processor; 6-pin or 8-pin PCI Express connectors for powering graphics cards; SATA power connectors for hard drives, SSDs, and optical drives; and Molex connectors used for devices such as older hard drives, case fans, and optical drives. Proper usage and management of power connectors are essential to ensure the efficient and safe functioning of computer systems.
Guide: CompTIA A+ - Cabling Connectors / Power Connectors
Importance: The power connectors are essential components of the computer as they supply power from the power supply to the different parts of the machine. Understanding power connectors is pivotal to maintaining and troubleshooting hardware issues. What it is: Power connectors are electrical connectors that distribute electricity to the various parts of the computer system, like the motherboard, hard drives, CD/DVD drives, graphic cards, etc. The connectors types include Molex, SATA, Berg, and ATX 12V, among others. How it Works: Power connectors function by delivering the right amount of electrical power from the power supply unit (PSU) to different peripherals and components. Different components require different types and amounts of power, so a variety of power connectors exist. Exam Tips: Answering Questions on Power Connectors 1. Familiarize yourself with different types of connectors and the devices they power. 2. Understand the differences in pin numbers for different power connectors; it can be a common question. 3. Diagrams of connectors may appear in your exam. Be able to recognize different power connectors from these diagrams. 4. Questions may focus on troubleshooting power issues, so comprehension of how different connectors supply power is crucial. 5. Always review the latest CompTIA A+ exam objectives to focus on the most pertinent topics.
