The Power Supply change over’s your consistent family unit current into low DC voltage utilized by the PC. At the point when this part fails,there is essentially no action going ahead with your computer.Remember to do the simple investigating first.Inspect the Power Supply for any damage.Double-Check all associations.

Figuring out how to check your capacity supply and how to supplant it when required can be a lifeline in case you’re a PC buff or in business with the trusted PC.Don’t underestimate the straightforward joy of turning on your PC and everything works fine and dandy.

We turned on one of our PCs as of late and in around one hour,it just re-booted itself.And it kept doing as such around 10 times each day until the point that we discovered the power supply was the culprit.Things to search for when your capacity supply is turning sour or just bites the dust on you are the accompanying.


Here you should first check the divider outlet for control by associating another gadget, for example, a radio or light to make sure power is present.If the PC is associated through a surge protector,check it also.

In the event that the divider out has power,check the power link setting off to the PC to check whether AC voltage is advancing toward the framework unit.Do this with the utilization of a multimeter.

In the event that there is power,you should open the PC and check for control from the power supply to the motherboard.

When utilizing a multimeter to check voltage,be beyond any doubt you have a decent ground for the dark lead of the multimeter.


One principle issue you may look with a sickly Power Supply is that it might re-boot the PC with no warning.All data is lost and it appears just as this occurs even under the least favorable conditions conceivable time.

Booting mistakes when the PC first start’s up is another pointer of this part going on the flicker.


At the point when the power supply starts to fail,you may get control at one gadget and not another.For example,the Hard Drive may get control but rather the CDROM Drive has nothing by any means.

Another cerebral pain with would cause re-booting is the irregular power setting off to the drives or the motherboard itself.Follow the means beneath to check your capacity supply should you encounter a portion of the above issues.


In the event that the divider outlet,and the power rope are good,make certain the association at the motherboard is secure.Then you may need to confront the way that the power supply itself is bad.If you have a Multimeter you can test the power supply yield before buying another one.Simply take after these means.

Kill the PC,but don’t unplug it,open the framework unit. Set the multimeter to peruse DC volts in the following reach higher than 12 volts.Locate a power connector similair to the hard drive,or cdrom drive connector that is unused and turn on the PC.

You can likewise unplug a drive connector and utilize it as well.Turn on the PC and embed the BLACK test into the power connector on one of the BLACK wires.Touch the RED test to the YELLOW wire on the power connector.

The multimeter perusing ought to be +12 volts Now contact the RED test to the RED wire and the perusing ought to be +5 volts.If no readings or diverse readings happened, you’ll need to supplant the power supply.If the readings were correct,you should check the P8 or P9 connectors at the motherboard. These connectors may likewise be named P4 and P5.To check these connectors,perform the accompanying…

Embed the BLACK test into P8 at one of the BLACK wires. Embed the RED test into the P8 connector at the RED wire. The perusing on the multimeter ought to be +5 volts

Check the power heading off to the Motherboard associations by embeddings the RED test into P8 at the YELLOW wire and you ought to get +12 volts.Leave the BLACK wire contacting the dark wire at the P8 connector.Check the BLUE wire and the perusing ought to be a – 12 volts.

Presently move the BLACK test to the BLACK wire on the P9 connector.Test the WHITE wire by embeddings the RED test and the perusing ought to be – 5 volts.Check the RED wires on the P9 connector and you ought to get +5 volts on every red wire.You won’t get precisely 5 or 12 volts however the readings will be close, for example, 5.02 volts.

On the off chance that the Power Supply is two or three volts off,in either direction,such as when the RED wire ought to peruse – 5 volts yet it peruses – 8 volts,or if there are no readings,replace the power supply.

Try not to expel the power supply from the framework unit situation when playing out these tests.DO NOT play out these tests on the off chance that you don’t feel comfortable.Be beyond any doubt to evacuate all electrical static develop from your garments and body BEFORE contacting any parts inside the framework unit.And NEVER open the power supply case for any reason,since high voltage might be available.
