Computer Power Supply : What is it?

Computer Power Supplies

Computer power supply, also called power supply units (PSUs), provide power to the computer and its components from an AC source. They also convert AC mains power to lower DC voltages to be used by individual components. Several wires connect the power supply to other components, including the motherboard and certain types of graphics cards. They also have dedicated cooling systems to help regulate heat and reduce energy loss.

Types of Computer Power Supplies

Kinds of Computer Power Supplies include the following:

Internal power supply

  • Internal power supplies are installed at the back of the computer case, with a cord connecting them to the AC source.
  • They are better protected from dust, moisture and outside elements than modular PSUs.
  • They tend to clutter the computer case and may be difficult to troubleshoot.


Modular power supply

  • Modular power supplies are housed outside the computer case.
  • They have several cables that the user can plug to preferred devices.
  • They free up space inside the computer space for better airflow, but are more prone to damage from outside elements.

Choosing Computer Power Supplies (Buying tips)

Wattage: Choose a power supply with a power output of 300 to 500 watts to power all the components during regular use. For heavy applications like gaming and multimedia, look for one with about 500 to 800 watts. Choose a higher wattage if you plan to add components.

Number of connectors:
Choose a power supply with enough connectors to power all the internal components. Look for extra 4-pin connectors for additional components, but make sure they do not crowd the computer case.
