Hello,

I do not know if my PC power supply is broken because my screen comes on. When I plug the power cable in my Box does not go on, the fans do not even run. Can you help me in this regard?

Many thanks in advance.

You should have it tested by a pro, unless you have a tool to test it yourself.

Could be the computer or the charger. You can take a meter and check the power adapter or replace it. That's the most common failure.

Hi!

The power supply can be tested separately. It must short-circuit with a wire (or a simple paper clip) two wires on the main plug. Sadly I don't remember exactly the wires but this information could be easily found on the web. If you do that and if your power supply doesn't start then it is broken.
