How to Choose a Power Supply for Your Computer
What is a power supply unit?
- Despite the name Power Supply Unit A PSU does not supply power to the device itself. Instead, these units convert one form of electrical current, namely alternating current (AC), into another form, namely direct current (DC).
- Additionally, they help regulate the DC output voltage according to the power requirements of the internal components. Therefore, most power supplies can operate in different locations where the input power source may vary. For example, the voltage is 240 volts 50 Hz in London ، 120 volts 60 Hertz in الولايات المتحدة الأمريكية , And 230 volts 50 Hz in Australia.
- PSU units are available from 200 To 1800 Watts, as needed.

The switched mode power source is considered (SMPS) It is most commonly used due to its wide range of advantages, as you can feed multiple voltage inputs simultaneously.
Why is a PSU necessary?
If your PC doesn't get a proper power supply or the PSU is faulty, you may encounter several problems such as:
- The device may become unstable.
- May not be preamble Your computer from the start menu.
- When energy demand is not met appendix Your computer may shut down improperly.

- However, for computers and desktops, you should prefer to purchase a Silver 80 Plus power supply and below, with an efficiency of 88%.
Note: The difference between 90% and 94% efficiency can have a significant impact on the energy used by large-scale data centers.
How many PSUs are enough for a computer?
In general, you'll need two power supplies for the server. Their operation depends on the frequency required by your computer.
- It is a smart way to have a completely redundant power supply system with Shut down PSU all the time, use it only in case of failure.
