Different people have different requirements which they need to fulfill by taking care of budget as well.Sometimes they often tell that they need a dual core,core 2 duo or quad core processor with 2,4,6 or 8 GB memory and 500 GB,1 or 2 TB HDD.Depending upon their requirement I need to take care of the computer`s requirement as well which is the Power Supply also knows as PSU ( Power Supply Unit ).As you all know that there is a black wire from the UPS going at the back of your computer tower apart from the other cables like keyboard,mouse,monitor.So the computer part on which that cable is connected is called the PSU which converts the AC ( Alternating Current from the wall ) to DC ( Direct Current for different components ).
Choosing a right PSU is very important that protects the computer parts from any kind of damage as different people have different requirements and depending upon their need I need to calculate the computer`s need that I do using different PSU calculators.I use two of them and also among these two the one that I mostly use is the Cooler Master`s Power Supply Calculator as this is the brand among the top brands easily available in my country.So depending upon your computer`s configuration you can calculate the required power supply for it and can easily calculate if your custom built machine has the right PSU or your local tech has just placed a cheap and lower power supplying unit to save few $$
Depending upon your expertise you can select either the standard or advance option from the top right side of the page.Once you select the desired parts that you will be purchasing for the custom build simply click the calculate button at the bottom right as shown below and it will display the required power for your computer
There would be many Asus lovers there so they can also use the power supply calculator at the below link
The Asus PSU calculator automatically does the calculation as shown below once you keep adding the components unlike the Cooler Master calculator where you need to press the button
There are other PSU calculators other as well but I use the above mentioned as these are the brands I mostly choose apart from other ones available there.If you use a different one do let us know and dont forget to share your favorite PSU company and the most famous one in your country.So no matter if you are using a Cooler Master,Antec,Seasonic or Corsair PSU,just check out if you are feeding your computer with the right power or not .
