Choosing the right PSU
 |
Power Supply Unit or PSU is a very crucial part of your computer, you can call the heart of your computer providing blood (read power) to all the components. Many PC builders in order to reduce cost use cheap unbranded PSU’s which later causes bigger problem like hardware failure etc. So here are some points to remember while purchasing a PSU for your computer. | ||||||||
|
1. Look for a branded model. Its not necesary that insanely priced brands will be best for you. You can very well relay on well priced cheaper models from brands like Corsair, Coolermaster, Antec, fsp group, etc. 2. When you have chosen some of them and want to find best one, how about weighing them? Yes its true that heavier the PSU’s, better it will be. Well built PSU’s have more components, heavier heatsink and large capacitors making it little heavy but very reliable too. |

| but if its there, its better),its diameter should be as big as possible since huge fan will need less RPM to throw hot air out thereby reducing the noice caused by it. Smaller ones sound like a jet engine and even don’t work well despite of their high speed. A relatively slow but bigger fan will perform better. | |||||||||

4. You must have seen lots of unused wires inside your computer emerging from PSU causing lots of trouble in servicing and working as a barrier in smooth air flow inside cabinet. To reduce this wire clutter now some brands use modular connectors so that you can remove those power cables which are not in use. This is a very good feature as more cables can be connected when needed so you never fall short of them. 5. What about wattage? For normal PC a 350W is more than enough, however if you have recently added a heavy graphic card and a fatter hard disk then you need a 500W monster. The thumb rule here is, the more the number of devices connected to motherboard, the higer wattage you need. |
