How PC Power Supply Works

Power Supply is a very important part in the computer , without the computer power supply you will never live . Power Supply is one of the least understood components in the PC and at the same time the power supply is one of the most important parts . When the power supply has been bad or improper use , your computer will also be problematic . Well , I will explain to you how important the power supply to the computer .


As I mentioned earlier the power supply is a very important part in the computer . If you are planning to do a major upgrade on your computer , it's good power supply will also be replaced because it will affect the performance of the computer .

Then how do you know you are bad power supply ? Well , here I will explain the problem to you . There are a few things you should know such as overheating , failure or error on boot , appears sound , and even electric shock when you touch a PC .

If the power supply shows signs such as these examples , it may be time power supply needs to be replaced . Never try to repair it yourself if you have no experience . It's safer if you want to fix it take it to a technician or an expert . Or if you do not want to bother just buy a new one just practical , right?

Power supplies are rated by the output of watts . Computers are older models usually have or take a power of about 70 watts . In contrast to today's computers , the average computer is currently using and consuming about 230 watts or 250 watts or even more . If you buy a new power supply , buy the one with the meticulous and it would be nice also if you know the brand of the power supply is good .

The basics of how a power supply works .
Power Supply to change the default power is 120 volts of electricity into a form that can be used by your computer . Typically , motherboards , adapter cards , and disk drives require at least a 5 volt power , cooling fan or cooling requires 12 volts .
The power supply also affects computers especially at boot time . Since the power supply is sending power to the motherboard and make sure that the system has enough power to operate properly .
Major fan of your power supply is also very important because the power supply had to keep the temperature of the computer . And you always check the cooling fan power supply because it draws air through the vents and out of the hole in the back of the power supply . Therefore , before the PC is turned on make sure the power supply is good airflow and no dust attached .

AT vs. ATX
AT power supplies arguably the most common , simple and does not take a great power . While ATX require special power . ATX contains special circuitry that allows for at least 5 volt power supply to the motherboard even when the computer is off .
The fan on the power supply has ATX usually air flow is reversed . So that blows air into the PC released through the fan on the power supply .

Connector .
When the power supply is working , there is nothing you need to know about some of the connectors . The most important thing if you are using a new PC , you may need to connect the power cord to the power switch on the PC . Some people have trouble doing this , because there are four wires , and four tabs . In general, you will find four wires color .

The cables are color coded as follows :

Brown and blue cables are wired with 110V power .
They bring 110V power to the switch . They will always be hot when the power is attached .
Black and white wires carrying AC current entry into the power supply .
These wires will be hot when the system is active or PC you live , because in fact switch closes the circuit .
If you have a green wire , there is sometimes a line, it is a ground wire .
When connecting , place the blue and brown wires on the tab parallel and side by side .
Then place the black and white wires to the tabs that are angled and in addition to the blue wire .

I noticed a lot of people can put these wires without a problem , but you should ALWAYS make sure the position of the black and brown wires are right next to the blue cable .
Connectors are all pretty much the same , except for different size alone . There are some people sometimes ask about the pin , he is .

1 Yellow 12 V
2 Black Ground
3 Black Ground
4 Red +5 V

What can you do to make your power supply is more durable ?
Home computers are usually environmentally friendly . This means that the fan inside the PC works well in order to keep your computer cool and stay cool and also free of dust .

Try to minimize the amount of dust and pollution in the air around your computer , because the fan draws air into the PC . You also may have noticed holes in the power supply fan is covered with dust , make sure you always clean it because it will affect the performance of the power supply .

Use stavolt or better stabilizer or UPS so that power surge that enters your computer through a cable is not great . For UPS I suggest you use UPS already has a stabilizer so that if the power supply voltage being unstable alias up and down you do not worry your computer will be problematic or damaged .
