What power supply do I have? How to find out

A power supply is a delicate component of your computer. If you want to renew this, you should first know which one to order. In this regard, it is really easy to find out which power supply for your PC you need to look for. You don't need IT knowledge for that.

How to find out which power adapter you need

The good thing is that a power adapter does not send any data to your PC, it is only responsible for transmitting power. Therefore, although damage is annoying, it can usually be fixed quickly.

• First, turn off your computer completely and disconnect the device from the mains. Now wait a few minutes until the computer has cooled down.
• Carefully open the case. If you have to unscrew screws for this, make sure that you keep them carefully.
• On your power supply you will find a sticker that gives you all the relevant data, such as the power in watts as well as the volts.
• In the case of the laptop, you do not even have to open the device to find out which power supply you need. Turn the power supply over and look at the sticker. The data for the input, the output and the volt and wattage numbers must be identical.

Must it be a brand spare part?

Of course, each manufacturer offers its own spare parts. However, these are often rather high-priced and not necessarily better than a no-name product. It is important that the technical data clearly match your old power supply, so that you do not risk overvoltage damage. Meanwhile, there are also power supplies where you can manually swap the connectors. This makes a power supply multifunctional.
