A power supply is a component that supplies power to at least one electric load. Typically, it converts one type of electrical power to another, but it may also convert a a different form of energy – such as solar, mechanical, or chemical – into electrical energy. A power supply provid...
A power supply is a hardwarecomponentthat 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. It also regulates the voltage to an adequate amount...
A power supply is a device that takes an incoming electrical current and amplifies it to levels required by various devices. The...
A power supply unit does just supply power to your computer. Its function makes the power enters your system from an external power source and is then allocated by the motherboard to individual component hardware. Not all power supplies are made equally, however, and without the correct wattage...
A power switch is a device that allows you to turn an electronic device on or off. It's like a toggle switch that controls the flow of electrical power to the device. When the switch is in the "on" position, it completes the circuit and allows electricity to flow, powering up the de...
An uninterruptible power supply is something you might not think about until you really need it. MF3d / Getty Images It's a foundational element of device integrity, but you wouldn't be the first person to beg the question, "What is a UPS?" In short, a UPS safeguards electronic device...
The open-collector output of a power supply is a method of control circuitry used to output the state (status) and other information of the power supply. Alternatively, an open collector may be used as an example of a circuit method to externally control the power supply, such as output ON...
A connection for the power cord to the computer. A fan opening to heat out of the power supply. A red switch to change the power supply voltage. A rocker switch to turn the power supply on and off.On the front of the power supply, which is not visible unless the computer is opened...
For power users, there is also the E-ATX form factor, which has more space for ports and expansion slots, but requires a large PC case to accommodate it. Power supply: Other than its CMOS (complementary metal-oxide semiconductor or microchip), which is powered by a replaceable CMOS battery...
What Is an Uninterruptible Power Supply? An uninterruptible power supply, or UPS for short, is a device that allows sensitive electronic devices — such as a desktop computer or server — to continue running for a short time – when on-grid power fails. ...
