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.
It is not recommended to replace a 350 watt power supply with a 300 watt power supply, as the lower wattage may not provide enough power for your components. It's best to match or exceed the wattage of the original power supply to ensure proper functionality of your system.
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.
If the power supply still works then yes.
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.
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.
No, a 5V 500mA power supply cannot run a 5V 1.8A device. The device requires 1.8A of current to operate properly, while the power supply can only provide 0.5A. Attempting to use the lower-rated power supply could result in insufficient power, causing the device to malfunction or not turn on at all.
yes, the power supply provides power specifically to the motherboard in turn dispersing power to all components plugged into the motherboard, hope this helped :)
Yes, you can use a 15V power supply rated for 500mA with a device that requires 15V and 600mA, but it may not function properly. The power supply will likely not provide enough current to meet the device's needs, which could lead to underperformance or potential damage to the power supply. It's always best to use a power supply that matches or exceeds the required current rating for optimal performance and safety.
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.
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.
