If your power supply isn’t working, there are a few steps you can take to try and diagnose and troubleshoot the issue. Before starting any work on your power supply, it’s important to unplug it from the power outlet, and to make sure the unit is completely disconnected from any other connected hardware.
1. Check That The Power Supply Is Plugged In Properly:
The most obvious thing to check is that the power supply is plugged in properly. Make sure the cord is fully inserted into both the wall outlet and the power supply. You should also check the wall outlet with a circuit tester to make sure it is receiving power.
2. Check Your Fuses:
If you have an older power supply, it may have fuses. If so, make sure they are intact. If they are blown, replace them with a new fuse of the same rating.
3. Inspect The Cable Connectors:
The next step is to inspect the connectors on the power supply. Make sure all of the cables are securely connected and free from any damage or corrosion. If you find any damaged or corroded connectors, replace them with new ones.
4. Test Voltage Output:
Using a multi-meter, you can test the voltage output of the power supply. Power supplies typically come with a label specifying the nominal output. Make sure the voltage output matches this value. If not, it could mean the power supply is defective and needs to be replaced.
5. Check For Overheating:
Make sure the power supply is not overheating. If it is hot to the touch, it could indicate there is a problem with the fan or cooling system. Check to see if the cooling fan is working properly and if the exhaust vents are unobstructed.
6. Listen For Unusual Noises:
Listen for any unusual noises coming from the power supply, such as buzzing or whirring. Any odd noises could indicate a problem with the internal components.
7. Check Your Computer System:
If none of the above steps shed any light on why your power supply isn’t working, it could be due to a problem with your computer system. Make sure everything is connected properly and that it is receiving power.
8. Try Plugging Into A Different Outlet:
If none of the above steps work, try plugging the power supply into a different outlet. This could help you determine whether the problem lies in the power supply or in the power outlet itself.
9. Have A Professional Look At It:
If none of the above steps resolve the issue, it’s best to have a professional look at it. A qualified technician can help you determine the exact cause of the problem.
Ultimately, knowing what to do when your power supply isn’t working can save you time, money, and headaches. With some basic troubleshooting steps you can usually identify and rectify the issue without having to call in a professional.
