Power supplies are the most common failure point in a PC. Check for these:
- Broken Power supply unit (even if nearly new)
- Lack of power in the cable
- Blown fuse
- 20 or 24 pin ATX power connector not seated correctly
- 4 pin CPU power cable not seated correctly
- cable from front panel power switch to motherboard connector disconnected

Can a computer cause a fire?
Yes, a computer can potentially cause a fire if there is a malfunction of the power supply, overheating of components, or electrical shorts. However, such incidents are relatively rare and can be mitigated by using proper equipment, ensuring proper ventilation, and regular maintenance of the computer.
What a computer power supply does?
a computer power supply (PSU) provides poer to all the components in the system and makes sure they they do not too much power to overload them or not enough to cause them to shut off
What is power supply?
If it is a computer power supply it is the box that gives the computer its power from the outlet.
What effect does a power spike have on a computer?
A power spike - also known as a power surge - could harm a computer if the computer's power supply has a low joule (unit of energy) rating. A power spike, a sudden increase in energy, can overwhelm a computer's power supply and cause too much electricity to flow to sensitive chips and processors and destroy them. To safeguard against power spikes a surge protector should be bought. A computer power supply with a high joule resistance rating would work as well.
When a computer begins displayaing intermittent errors what is the likely cause?
Its either the memory or the power supply
What supplies power to a computer?
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.
Can the power supply cause the computer to be difficult to turn on?
Yes. If the power supply is of a low wattage and has too many pieces of hardware connected to it, it can. Try buying a power supply with a wattage over 300. One thing to check before replacing the power supply is the voltage selector in the back. If you use 120 volt power, then setting the power supply to 240 volts will cause the PC to only get half of the power it needs. External peripherals with their own power supply will not impact the power supply or current in the computer. Printers and monitors usually get their power from the wall socket, not the computer, and the same goes for external modems that plug into the wall. Keyboards and mice take negligible power.
What can cause a faulty power supply?
A faulty power supply does not supply any power at all to a computer or supplies incorrect voltages. Most of the time faulty power supplies are not serviceable and require replacement.
When do you need to replace the computer power supply?
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.
What is fuction of 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.
What should you use to provide power supply to your computer?
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.
Is used to prevent the effect of power fluctuation in the power supply on your computer and works for a specific period of time even there is no power.?
