It is necessary to replace a PC power supply when it starts to wear out.With the help of this guide and a few simple tools, you can do this job yourself and save money.
Step 1: Make sure that everything is plugged in.
It is possible that a cord could slip out of the outlet while you are working.There is a chance that your power supply is malfunctioning if there is no power to your computer.
Step 2: You can hit the power button.
The system won't do anything when you hit the power button.The power supply will probably die if there is no sound or monitor activity.This can be caused by a faulty switch, but it's usually the result of a burned-out power supply.
Step 3: When your computer boots up, look at that.
Changes in how long it takes for your computer to boot up and shut down could be a sign that something is wrong.
Step 4: Check to see if there is a sound.
This could be linked to the power supply if the system makes rapid, short beeps repeatedly and does not boot when you try.
Step 5: Look at computer failures.
There are a lot of things that can be related to your power supply.
Step 6: There is a fan in your computer.
If the fan in your computer doesn't spin, it can cause overheating, smoke in the system, and a failure of the power supply.
Step 7: You should be familiar with the proper procedures.
Before doing any kind of PC repair work, this should be done.You may damage your computer if you neglect this step.
Step 8: The machine needs to be disconnected from all the external connections.
The keyboard, mouse, network cable and speakers are included.
Step 9: The power supply unit should be named.
It will be connected to almost every component inside the computer case.
Step 10: Remove the case cover.
Attach the power supply to the housing with the screws on the back of the case.The screws should be placed in a handy location.
Step 11: Remove the old power supply from the case
If there is little room in your PC, it may be necessary to remove other components to get the power supply out.If you don't feel comfortable removing other components, replace the mounting screws and get the help of a PC expert.Don't pull the power supply out by force.
Step 12: Purchase a new power supply that is the same type as the previous one.
Most power supplies used in modern computers are of the "ATX" variety, but if you aren't sure, take the old unit to the store to compare.The old unit should be the same width as the new one.If the new unit is a bit longer, it's fine.The salesperson or technician can help you identify the correct unit.
Step 13: Make sure the power supply is fit for purpose.
Some cases might get in the way if the new unit has a large bottom mounted fan.Attach the unit to the case using the mounting screws.
Step 14: The devices in your PC should be connected to the new power supply using proper procedures.
The connections should be the same.If you have to strain a lot to push them in, you may be trying to connect them backwards.If you are determined and strong, it can be done.Turn the connector around if you have to force it.
Step 15: If there are cables stuck in the fan or other moving parts, make sure they are out of the way.
The processor can be destroyed very quickly if the fan is stopped.You may want to restrain unused cables to keep them out of the fans.
Step 16: The case cover should be replaced.
Step 17: All external connections to the back of the computer need to be replaced.
Enjoy your new power supply when you power up the system.If your power supply fails, your system could fail.
