A power supply unit is a device that supplies electrical energy to one or more electric loads. As a computer part, the PSU supplies power to the rest of the computer. The power supply unit converts wall current into the right kind of power for the individual parts of your computer. The current produced is clean direct current that is 12 volts, 5 volts, and other correct voltages. The PSU then distributes the power throughout the system internally to hard drives, DVD/CD drives, floppy drives, GPU's, the motherboard and any other parts as well.
When your computer will not power on. When the cooling fan of the power supply has failed. When the amount of hardware in use in your case exceeds the power capability of your power supply.
The PC power supply box's function is to supply the computer with power. Without the PC power supply box, the computer would not be able to turn on and off.
UPS = Uninterruptible Power Supply
normally the power button :)
The power supply's power-good signal prevents a computer from operating on improper voltages and potentially getting damaged. Typically, a computer will only start up after receiving the power-good signal.
If it is a computer power supply it is the box that gives the computer its power from the outlet.
The "power supply" supplies power to a computer. A computer's power supply is a "switchmode power supply" responsible for converting the AC voltage from the wall into several DC output voltages.
When your computer will not power on. When the cooling fan of the power supply has failed. When the amount of hardware in use in your case exceeds the power capability of your power supply.
The power supply makes the computer run, without any type of power supply it would be impossible to run a computer. The mains power supply for a laptop and the power supply unit of a desk top, both convert the high AC voltage from the mains power and convert it to low voltage DC, for the electronics of a computer to use.
In order to supply power supply to your computer you would need an outlet plug near your computer. Then you can plug your computer into that and necessarily, use an extension.

To power all the components of a computer.
The PC power supply box's function is to supply the computer with power. Without the PC power supply box, the computer would not be able to turn on and off.
Use a power supply tester. You can get them on ebay for under $5.
Cisco power supplies are computer parts. The power supply is the part of a computer that receives electric power from a plug and sends that power to the other parts of the computer. Power supplies also include fans to keep the computer at a reasonable temperature.
Your computer can run as long as there is a power supply. As long as the power is on you should have no problem
