How to choose right PSU for PC

Choose a psu for u

PSU is the most misunderstood part of PC. Most of the peoples ignore this part while buying PC for them. Most of the users choose that power supply for their PC which is totally based on wattage alone. They just think that higher is always better. They consider PSU just like other specs of PC that higher is always better. While there are also some users who even don’t pay attention on this part while setting PC for them. They settle for any abomination arrived with machine. It’s very important to choose a good power supply because the system stability and its long term reliability depend on PSUs. It’s a bitter truth that PSUs get little attention as compared to other components like RAM, SSD and graphics cards. 

Here we have mentioned some tips through which you can get best PSUs for your PC.

  • There is no single rule for choosing PSUs but there are some recommendations through which you can address your PC with perfect power supply. The first thing you have to consider is to always buy a power supply from reputable manufacturer, and also looks for its reviews before buying it. Just ignore cheap and generic power supplies which tend to be substandard. Go for reputable brands who offer solid warranties and support. There are three recommended manufacturers Corsair, Seasonic and Antec with reputations for manufacturing best quality power supplies. 
  • Moreover high quality power supplies always use big and better capacitors, chokes and more internal components. While they come outfitted with larger heatsinks for superior heat dissipation.  These also have larger cooling fans which move more air and produce less noise as compared to small fans.
  • The next thing you have to check in power supply is to check PSUs connectors for confirming that whether it is compatible with your system or not. There is a term 20+4 pin which refers to a connector that can work as both 20-pin and 24-pin connector. While 6+2 pin connector can snap two pins in connector on or off suits to your needs. 
  • Most of the PCs use standard ATX power supplies. There are also smaller units available which are designed for enterprise and server applications. But for common desktop systems there are ATX power supplies. When you are looking for a power supply keep three features in your mind that are power output, rails and efficiency. There are also other important specifications and features but the above three features have direct impact on PSUs performance. 
  • Most of the manufacturers list their power supplies output in watts. If there is a high-watt PSU so it can supply more power. Desktop power supplies have a power output ranging from 200 to 1800 watts. Here the important number is for continuous power not for the peak power. Most of the power supplies can operate peak power which is only for brief periods. Wattage ratings higher than 1800 exceed the capabilities of typical 15-ampere electrical outlet. 
  • The important thing which makes PSU a better PSU is its efficiency rating because the high-efficiency units tend to have better components also it wastes less power and generates less heat which tends to less fan noise. A power supply which has efficiency rating of 80 percent gives 80% of its     rated wattage power to your system. While it loses rest of the 20 percent as heat. 
  • In addition for identifying output power manufacturers specify number of +12V rails their PSU contains. If there is a single-rail power supply so there is also a single high-power +12 rail for feeding power to those components of system which are hungry.
