A power supply is an electrical device that supplies electric power to an electrical load. The main purpose of a power supply is to convert electric current from a source to the correct voltage, current, and frequency to power the load. As a result, power supplies are sometimes referred to as electric power converters.

Feb 21, 2025 · Abbreviated as PS or P/S, a power supply or PSU (Power Supply Unit) is a hardware component of a computer that supplies all other components with power. The power supply converts a 110-115 or 220-230 volt AC (Alternating Current) into a steady low-voltage DC (direct current) usable by the computer and rated by the number of watts it generates.

Jan 28, 2009 · A power supply is a hardware component that supplies power to an electrical device. It receives power from an electrical outlet and converts the current from AC (alternating current) to DC (direct current), which is what the computer requires.

Learn what a power supply is, its key functions, and how it converts electricity, ensuring your devices operate safely and efficiently.

Dec 20, 2023 · Power Supply Units (PSUs), despite their name, transform power rather than providing it to systems. In particular, a power supply regulates the DC output voltage to the precise tolerances needed for contemporary computing components in addition to converting the alternating high voltage current (AC) into direct current (DC).

What is a power supply? A power supply is an electronic device that converts incoming electrical energy from a source into the appropriate voltage, current, and frequency required to power electronic devices or components. What are the different types of power supplies?

May 30, 2024 · What is a Power Supply Unit (PSU)? A Power Supply Unit (PSU) is a crucial component of a computer system that converts electrical power from an external power source into usable power for the internal components of the computer.

A power supply is an electrical device that offers electric power to an electrical load such as laptop computer, server, or other electronic devices. The main function of a power supply is to convert electric current from a source to the correct voltage, current, and frequency to power the load.

A power supply, unlike a battery, is constant power and can usually be set over a wide scale of voltage and/or current. This unit gets its power usually from the grid or mains.

What Is Power Supply And Its Function? A power supply is an electrical device that provides electric power to a load. Its main function is to convert electric current from a source to the correct voltage, current, and frequency needed to power the load.
