A power supply. Most efficient computer power supplies are switching power supplies. See switching power supply for further clarification.


Power supply...A computer's power supply converts alternating current (AC) from the wall outlet to direct current (DC) used by the computer's internal components.AnswerA rectifier is used to convert a.c. to d.c.


The power supply of the computer is where the electrical current from your outlet is sent and then dispersed throughout the components in your computer.


In the case of a desktop computer a power supply that in turn plugs into a household outlet provides power to the internal components of the computer. In the case of a laptop or tablet a battery provides power.


In a computer, the main energy used is electrical energy in the form of direct current. The power supply converts AC to DC and delivers electricity to all of the components.


A computer power supply takes the AC power coming from a wall socket, and then converts it into lower-voltage DC to power all the components inside. Almost every component of a computer will connect directly to the power supply, with the exception of smaller parts such as fans, which can pull power through the motherboard.


By uninstalling the inlet component


The power supply converts alternating electric current (AC) into a form that the computer use. It reduces the electric outlet voltage from 100-200 volts electric outlet Alternating Current (AC) to a lower voltage Direct Current (DC) used by the CPU and other computer components. The power supply generates heat which can be damaging to itself and the computer. To avoid this desktop computer power supplies have fans and ventilation to prevent overheating. In notebook style computers, the power supply is a module (box) separate from the rest of the unit so its heat does not affect the computer.


A PSU (Power Supply Unit) converts the power received from the wall outlet to the power power needed to supply power to the mother board and all other components within the PC.


A power supply receives 120 volts of AC power from a wall outlet and converts it to 3.3, 5, and 12 volts of DC power.


an AC Adapter allows you to plug your computer into a standard wall outlet


insert the plug from the computer into the wall outlet.


An extension cord is a long power cord that plugs into an outlet and receives with an outlet. A computer cord just uses one long cable to transfer power to the computer from the outlet.


Sometimes when people buy a computer power supply unit (PSU), there are several components in the box: a AC power cable to connect the power supply to the wall mains outlet, the power supply itself (PSU) that converts mains power into more useful forms of power, and one or more DC power cables that connect the power supply to the motherboard and other parts of the computer. (On a modular power supply unit, those cables can be detached from the PSU). A computer power supply is in a metal box that is difficult to open, so most people treat a computer power supply (PSU) as a single indivisible component. Inside a computer power supply is a transformer to help convert mains power into more useful forms of power, power diodes and power transistors typically mounted to a heat sink, and other components to help the conversion or to filter the power to meet EMC requirements, and often a fan to blow air on the heat sink to keep the transistors from overheating.





If it is a computer power supply it is the box that gives the computer its power from the outlet.


if the outlet is 20A it's ok on a 15A outlet depends what you what to run it may be too much.


You can't. HDMI is digital. RCA is analog (component or composite).


As far as I know, transistors - and other electronic devices - basically work with DC, not AC. If a computer (for example) is plugged into an AC outlet, some device within the computer must first convert the AC current into DC current, which is then fed to the electronic components.


A PC Main Supply is what gives the computer power to operate, in desktop computers they have to constantly be connected to some type of power outlet. Diagram. Plug socket > Cable > PSU (power supply unit) > Motherboard > power to all components in the computer.


The steps to switch on a computer begin with making sure that the computer and its peripherals are plugged into an electrical outlet. Turn the power switch on the electrical outlet and press the power button on the computer tower. Turn on the computer monitor and wait for the computer system to start up.


There are several components that must work properly for charging to occur.The battery - The battery must be rechargeable. Batteries that have been charge hundreds of times lose the ability to be recharged. Test this by putting the battery in another computer that does charge up, and see if it will charge the battery.The cable - the cable takes power from the outlet and puts it into the computer. Test this by using a different cable and see if the battery will charge. If the different cable will charge the battery, replace the old cable.The computer. Test this by putting a different battery in the computer and see if it will charge a different battery. If it will charge the different battery, replace the old battery. If your MacBook lacks a replaceable battery, take it in to a shop that can check or replace the battery.The outlet. The cable is plugged into an outlet. Check the outlet by plugging in a different device and see if the outlet is in fact providing power to the cable.


A computer port is a specialized outlet to which a variety of devices can be connected to a computer. Ports are classified as either male or female.
