What is a Power Supply and how does it work?
A Power Supply Unit PSU is the backbone of any electronic system and one of the most crucial internal IT hardware components. Power Supply Units PSU do not supply power to the system instead, they just convert it. Particularly, a computer case with a power supply
is responsible for converting the alternating high voltage current AC into direct current DC. In addition, the power supply also controls the DC output voltage to the fine tolerances needed for modern computing components.
It is the most fundamental component that feeds the system. It is important to choose the right power supply to make sure that the device works at optimum levels and delivers the best results.
Direct current power supplies can be either unregulated or regulated. Regulated power supplies are available in several options such as linear, switched, and battery based.
In addition, power supplies have massive 24 pin ATX computer power supply connectors.
The connectors provide 12V, 5V, and 3.3V to the motherboard and PCI E add in cards such as network cards and RAID controllers, entry level graphics cards, and sound cards. Asus
, and Gigabyte
are the best manufacturers of computer power supply cables.
How does Power Supply work?
• A power supply has an easy procedure to convert electricity and reduce ripple voltage.
• It starts with a transformer to reduce the electrical energy.
• The power supply then converts AC to DC power.
• Finally, the DC power passes through a regulator that cleans it by eliminating the ripple voltage.
