Depends on make and model. If you just open the side panel of the computer and look at the box on top were the power cord goes then it should say there.
Yes. Depending on the design, the power supply can provide any voltage desired.
yes
To provide power to the power supply which in turn powers the motherboard.
A dual power supply refers to a system that provides two separate power sources to a device or circuit. This setup offers redundancy and can help improve reliability in case one power source fails. It is commonly used in critical systems where uninterrupted power supply is necessary.
If the power supply still works then yes.
DC power supply is used to power the IC's and other active and passive devices.It is provide to amplify the weak signal with the help of amplifiers.
If another power supply doesn't work, it's likely your motherboard has failed. It could be that you need to buy a new processor. It may be "fried." However, there may be other causes. It could be as simple as reseating drive cables, power connectors, etc. There is not enough information in the original question to determine what the problem is. (Which fan is on, the power supply or CPU fan or one of the case fans?) A Power supply can be strong enough to get the fan going but not enough juice to power up the system! That ia a weak Power supply that can power up a fan but not the system, try another power supply.
yes, the power supply provides power specifically to the motherboard in turn dispersing power to all components plugged into the motherboard, hope this helped :)
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.
A UPS is an abbreviation for an "Uninterruptible Power Supply". The purpose of this device is to provide power when the main power source fails. UPS battery backups are used to provide power for computers, data centers and various other types of equipment. Typically the back-up is used with equipment that cannot have a disruption in the power supply, or equipment which may be damaged if there is a disruption in the power supply.

Not all pins are needed in a given configuration. Another possible scenario would be if your motherboard requires a 24 pin adaptor and the power supply only has a 20 pin interface. In this situation, the 20 pin could be plugged in and might provide adequate power to operate the basic components to make the system turn on and run. However, you will have power deficiencies most notably to the CPU. This could in turn be harmful to CPU, motherboard, power supply, etc. by components demanding more power than the available conduits can provide.
