If you are planning to do a major upgrade on your computer, it's good power supply also replaced as would affect the performance of the computer. So how do you know you are bad power supply? Well, here is the problem that I will explain to you. There are a few things you should know as overheat, failure or error on boot, appears sound, and even electric shock when you touch the PC.
If the power supply shows signs of such 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 or take it to an expert technician. Or if you do not want to bother just buy the newly practically right?
Power supplies are rated by watts output. Computers that older models usually have a power or consuming around 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, buying was carefully and it would be good also if you know the brand of a good power supply.
Power Supply converts the data standard of 120 volts into a form of electricity that can be used by your computer. Normally, motherboards, adapter cards, and disk drives require at least 5 volt power, cooling fans or cooling requires 12 volts.
Power supplies also affect computers especially at boot time. Because the power supply sends power to the motherboard and make sure that the system has enough power to operate properly. The main fan of your power supply is also very important because the power supply must maintain the temperature of the computer. And you always check the power supply cooling fan also 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 air flow and no dust is attached.
AT vs ATX
Power supplies OR arguably the most common, simple and does not take a great power. While ATX require special power. ATX contains special circuitry that allows for a minimum of 5 volt power supply to the motherboard even when the computer is off.
The fan in an ATX power supply that has typically air flow is reversed. So that blows air into the PC issued through the existing fan on the power supply.
Connector
When the power supply is working, there is a need to know about some of the connectors. The most important 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 color cable.
The cables are color-coded as follows:
- Brown and blue cable is wired with 110V power.
- They bring a 110V power to the switch. They will always be hot when the power is connected.
- Black and white wires carry the AC current into the power supply.
- This cable will heat when the system is active or PC you live, because the switch is actually closed circuit.
- If you have a green wire, sometimes there is the line, it is the ground wire.
- When connecting, place the blue and brown wires in parallel and adjacent tab.
- Then place the black and white wires on sloping tab and next to the blue cable.
Connectors all pretty much the same, except for a different size alone. There are some people sometimes ask about the pin, this he meant.
- Yellow 12 V
- Black Ground
- Black Ground
- Red +5 V
Home computers generally environmentally friendly. This means that the fan inside the PC works well in order to keep your computer in order to stay cool and airy also free of dust.
Try to minimize the amount of dust and pollutants 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 because it will affect the performance of the power supply.
Use stavolt or better stabilizer or UPS so that a power surge that enters your computer via a cable is not great. For UPS I suggest you use a UPS that already has a stabilizer so that if the power supply voltage unstable alias up and down you do not worry about your computer will be problematic or damaged.
