PC Power Supply Basic

PC Power SupplyThe function of your personal computer power supply is very simple: It distributes the required electrical power from the electric outlet to all computer devices. Power supply is responsible for transforming Alternating Current (AC) from a wall outlet into Direct Current (DC), because only in this way, computer hardware can work. Since each component requires a certain voltage, it will be distributed to 12 volt, 5volt and 3.3volt. Processors and graphics cards are the most widely used source of 12 volts.


Powefull PC Power supply working with two voltage rails. Splitting up of 12-volt rail voltage with a smaller board will help ease the load on other rail and prevent high voltage fluctuations.

Who wishes to buy a PC power supply should pay attention to the exact details power supply specs. There should be a device with “active PFC.” It means “Power Factor Correction”, or “power factor corrector.” When you choosing a power supply with passive PFC,  there are some disadvantages. The transformer is heavier and larger, this makes the performance even worse, higher consumption and increased smog.

A PC power supply with active PFC, distribute almost all power from the outlet. Power consumption can be kept low. Power supply with PFC highly efficient and low heat.Power  Efficiency of this power supply will not be lower than 80%.
