The 24-pin ATX power connector is the main power connection between a computer’s power supply and motherboard. It delivers essential voltages, including 3.3V, 5V, and 12V, to power critical components such as the CPU, RAM, and expansion slots. Introduced as an upgrade to the older 20-pin design, it provides better support for modern systems with higher power demands. The connector is keyed to prevent incorrect installation and is standard in most desktop PCs today.
