What is Power Supply PC?

A power supply unit (or PSU) converts mains AC to low-voltage regulated DC power for the internal components of a computer. Modern personal computers universally use switched-mode power supplies.

Some power supplies have a manual switch for selecting input voltage, while others automatically adapt to the mains voltage. Most modern desktop personal computer power supplies conform to the ATX specification, which includes form factor and voltage tolerances.

While an ATX power supply is connected to the mains supply, it always provides a 5 Volt standby (5VSB) voltage so that the standby functions on the computer and certain peripherals are powered. ATX power supplies are turned on and off by a signal from the motherboard.

 

They also provide a signal to the motherboard to indicate when the DC voltages are in spec, so that the computer is able to safely power up and boot. The most recent ATX PSU standard is version 2.31 as of mid-2008. Source : Wikipedia

Power Supply PC Problems

If you’re wondering why your computer can’t start a bright morning, the problem might be with the power supply unit. Actually, the computer power supply is the heart of your machine and needs to supply power permanently when the computer is turned on.

Of course, when a constant power supply is needed, you cannot expect it to fail without warning! So, it is very important that the power unit is strong and reliable.

The main function of your computer’s power supply PC is to go down and change your domestic power, which provides alternating current (AC), into Current (DC) Current.

Usually, each power unit equipped with a computer can theoretically last long enough for your computer to require an upgrade or even for a lifetime. However, sometimes, it can explode without warning and make you stranded. In this case, you have to replace it with a new one.

Even though you might be able to do this yourself, I would not advise you to do it if your computer is under warranty, or you can risk canceling it.

The best is that trained technicians handle damaged computer power units because there may be other problems related to non-functional computers that your technician might be able to find.

So have you conclude an ideas how to choose power supply PC for you?

How to Change Power Supply PC?

If you need to change the computer’s own power supply, you must first remove the case and then find the power unit on your computer and carefully remove it without damaging other components. Make sure you get a power unit with the same rank as your computer, otherwise you can land your computer on other serious problems.

Typically, your computer will need an AT or form factor power unit with an ATX form factor. Newer computers may require ones with SATA connectors with the recent emergence of SATA hard drives.

It is very important that your computer’s power supply is compatible with your computer’s motherboard. Computers that have older motherboards or with fewer features use a 20-pin ATX connector.

However, newer computers use a 24 pin ATX connector. It is possible to use a 24 pin power supply with 20 pins one but otherwise cannot be tried.

You can even use a modular power supply if you only need a certain connection or you can buy a standard power unit and connect important components and peripherals to your computer.

There is one thing you have to be careful about – just go in for more prominent and standard brands. If you get a lower power unit, then your computer is at risk again. If the power unit fails again, you must repeat the whole process again.

How PC power supply works?

Power supply work seems simple: to convert alternating current (A / C) to direct current (D / C) which, like most electronic devices, is what your computer uses. Inside the computer case, various cables and plugs are installed out of the power supply. This attaches to various components inside the computer.

Some high-end power supplies from OCZ, CoolMax, and Ultra allow you to only install the cables and plugs that you need. This can make less clutter in the case and help increase airflow which makes your computer work cooler.

Unfortunately, many computer manufacturers incorporate inexpensive power supplies that have very little power. Power supply is measured mainly in terms of wattage. Finding out how many watts a power supply can produce is the first way to determine if your computer system is at risk of power shortages.

Even today, some systems still deliver with a 150 watt power supply. This is hard to accept. The basic system must have, at least, 350 watts of power capability.

Many systems have 500 watts or more, and some high-end game systems are equipped with a 1000 watt power supply.

Our Power Supply PC Recommendation

The power supply of your personal computer must first be powerful enough to handle all the components that make up your computer together. If you have a powerful central processing unit with a powerful graphics card, a large hard drive, and fabulous memory, you need to have a sufficient supply to use all their capabilities.

Older versions of supplies have been designed to operate at a regular power of 300W. This is no longer the case because games and other programs require so much of your components that without constant and powerful power, they fail.

You can get by with a 500W power supply, but for the best games, programs and applications today, as well as on the work platform itself. However, the best choice you can make is to choose a power supply of about 700 or 800 W.
