What is a ATX power supply?

An ATX power supply is a power unit commonly used in desktop computers, based on the "ATX (Advanced Technology eXtended)" standard defined by Intel. It delivers stable power to multiple components such as the motherboard, hard drives, and graphics cards. ATX power supplies feature a 20-pin or 24-pin main connector, along with additional connectors for the CPU, GPU, and SATA devices. They also support power management features like software-controlled ON/OFF and standby modes. Known for their reliability and expandability, ATX power supplies are widely used in custom-built PCs and industrial computers.
