What is a Power Supply Unit? A power supply unit is an electronic device that regulates and converts alternating current (AC) from a wall outlet into direct current (DC) that internal hardware requires. The most common standard is ATX, but variations like microATX and mini-ITX exist.

Modern graphics cards utilize PCIe power cables, and older drives may require Molex connectors, so verifying compatibility prevents assembly delays. The 24-pin ATX connector powers the main board, while the 8-pin CPU connector supplies energy to the processor.
Calculating the required wattage involves summing the thermal design power (TDP) of the CPU and GPU, plus allowances for drives, fans, and other peripherals. Form Factor and Compatibility The physical size and mounting style, known as the form factor, must match the computer chassis.

Efficiency ratings indicate how much power is lost as heat during conversion, with higher ratings translating to lower operational costs. This technology dominates computer PSUs due to its ability to deliver high wattage in a small footprint while managing heat effectively.
