What is power supply and its types?

The power supply unit is the part of the hardware that is used to convert the power provided from the outlet into usable power to many parts inside an electrical device. Every energy supply must drive its load, which is connected to it. There are two types of power supplies existed, AC and DC power supply.

What is inside power supply?

Parts found inside a power supply A rectifier that converts AC (alternating current) into DC. A filter that smooths out the DC (direct current) coming from a rectifier. A voltage regulator that controls the DC output, allowing the correct amount of power, volts or watts, to be supplied to the computer hardware.

Does your power supply need a fan?

The power supply is equipped with an intake fan, which will draw in air from the environment. The air will then be exhausted through the back of the power supply. The placement of your power supply depends on the type of your computer case.

Is the power supply fan always on?

No, often the PSU fan will not run unless it is required to cool the PSU. It depends on a number of factors if the PSU will be that smart.

What are the 4 primary components of a power supply?

A power supply is an electronic circuit that converts the voltage of an alternating current (AC) into a direct current (DC) voltage. It is basically consisting of the following elements: transformer, rectifier, filter and regulator circuits.

What are the 4 stages of power supply?

Power Supplies

  • Transformer – steps down high voltage AC mains to low voltage AC.
  • Rectifier – converts AC to DC, but the DC output is varying.
  • Smoothing – smooths the DC from varying greatly to a small ripple.
  • Regulator – eliminates ripple by setting DC output to a fixed voltage.

Which power supply cables do I need?

Power Cables

  • 24-pin power to motherboard (always required)
  • 4/8-pin EPS12V power to CPU (always required)
  • 6/8-pin power to video card (normally required)
  • SATA power to storage devices (normally required)
  • MOLEX power to accessories (optional)
  • CPU fan & case fan power (required)

How do I know if my PSU fan is working?

To test your PSU:

  1. Shut off your PSU.
  2. Unplug all cables from the PSU except for the main AC cable and the 24-pin cable.
  3. Locate pin 4 and pin 5 on your 24-pin cable.
  4. Bend your paper clip so the ends can be inserted into pin 4 and pin 5.
  5. Turn on the PSU.
  6. See if the PSU fan turns.

What are the types of power supplies?

There are three subsets of regulated power supplies: linear, switched, and battery-based. Of the three basic regulated power supply designs, linear is the least complicated system, but switched and battery power have their advantages.

What is the function of a power supply unit?

Function of computer power supply The function of power unit is to convert the electrical power (AC) comes from wall socket to a suitable type and voltage (DC) so that each component of a computer works properly.

What is CPU power supply?

A power supply converts AC voltage from a wall outlet to DC usable by computers. The power supply unit is secured inside a computer tower and used to power all the internal hardware components. The power supply unit connects directly to a motherboard and powers it along with connected hardware components like the CPU and RAM modules.
