How to choose your PC power supply?
To choose the best power supply for your PC, you first need to know the power required by the components of a desktop PC to function properly.
If a power supply of between 300 and 500 W is largely sufficient for use in office automation or web browsing, it will be necessary to turn to a more powerful model for a more demanding configuration (for example for video games).
What is a PC power supply for?
The PC power supply doesn't just supply power to the components of a desktop computer.
It helps to reduce the voltage of the electrical outlet in order to properly power the components of the PC by limiting variations and electric shock.
In addition, it has a fan which plays a crucial role in managing surges or overheating of the various components (graphics card, motherboard, etc.).
With this selection of PC power supplies, you can easily find the model that will best meet your expectations. To summarize, the more your PC will be used (powerful graphics card, online games ...), the more you will need a powerful power supply and with a high certification (White, Bronze, Gold ...).
