Minimum power supply needed to run a computer
Power supplies are purchased according to the total output power that is needed by you and it depends upon the watts. It is very important that you find a right power supply for you. It will not only supply the required voltage but will also provide proper supply for the system for which you are using it.
The power needed for the computer is the most important and critical factor to take into consideration. A 5v power supply is mostly better for this situation. A computer generally uses a power of 3v, 3.5 v and 5 volts. A stable power supply is needed for the proper working of the components of the computer. If more power is supplied rather than the required amount then it can cause a lot of damages. It may even cause a short circuit and can damage the main useful parts of the computer.
Before connecting any supplies to any device its power should be check properly. The additional power supply measure meters are used for this purpose. They are used to check the voltage of the 3v, 12v, 3.5 v and 5v power supply devices.
There are different sources of power supplies which an individual can purchase. The voltage can be set according to the required need. The most common source of power supply now-a-days is the UPS. It is used in homes and offices. In the offices the computers are also run on this power supply system. It depends on you how much power is required by you. Whether you need a high voltage to run all the fans and tubelites or you just simply need a 5v power supply for your personal use only. The purchase decision depends on your choice and your requirement of the power supply.
