THE RIGHT PSU FOR YOUR PC

All of us are very enthusiastic when it comes to bulding our own PC. We select all the components that we need ranging from processors, GPUs and RAMs to name a few but we often forget or rather ignore the importance of a good & adequate PSU.

A PSU or Power Supply Unit is also known as SMPS or Switch Mode Power Supply, this component is responsible for handeling all the power requirements of your rig. So whenever you build a PC just keep in mind to pick up the right PSU that will matchup to all your components power requirements to keep them working safe n to their max potential.

HOW TO CHOOSE THE RIGHT PSU??

There is no single, universal rule for selecting a high-quality power supply. Nevertheless, various indicators provide circumstantial evidence of PSU quality, and some guidelines are generally helpful. So just keep the following points in mind:

• Always buy a power supply from a reputable manufacturer, and look for reviews of it before you buy. Avoid cheap, generic power supplies, which tend to be substandard. Look for reputable brands that offer solid warranties and support. Corsair, Seasonic, and Antec are three manufacturers with reputations for producing high-quality power supplies. If you go for Indian manufactureres then go for VIP. Do not go for cheap ones atall a good PSU is the backbone of all your components.
• You should also check the PSU's connectors to confirm the unit is compatible with your particular system. The term 20+4 pin refers to a connector that can function as either a 20-pin connector or a 24-pin connector. In the 6+2 pin connector shown at right, you can snap two of the pins in the connector on or off to suit your needs.
  The vast majority of consumer PCs use standard ATX power supplies. Smaller units and units specially designed for enterprise and server applications are also available; but for common desktop systems, ATX power supplies are it.
• All the vital system components work on the 12V rails ie they consume power on this particular volatge so whenever you pick a PSU just check that it is delivering a high output current on the 12V rail. An ideal PSu would deliver atleast 20W of power on the 12V rail just like in this particular one it is delivering 52A of current on the required frequency:

 

• Just in case it is a dual rail PSU then add up the output of both the 12V rails n the see the total like in the one below:

WHAT DO THE WATTS MEAN??

Manufacturers usually list their power supplies' output in watts. A higher-watt PSU can supply more power. Desktop power supplies have a power output rating of from 200 watts to 1800 watts.

Ideally your unit will delivers plenty of power to your components and offers some extra headroom in case you want to attach additional components later. Most power supplies hit their peak efficiency levels with loads in the range of 40 to 80 percent. Building to about 50 to 60 percent of a PSU's capacity is advisable to achieve maximum efficiency and yet leave room for future expansion.

For example, if the maximum power or combined TDP (total design power) of your system’s present components is 300 watts, a 600-watt PSU would be a good fit. In a high-end system loaded with components that may peak collectively at 700 watts, a 1200-watt PSU would work well. You can get by with lower-capacity units if you don’t think you’ll ever need to expand your system, but if you can afford it, choosing a higher-capacity PSU is a better bet.
