How To Choose the best SMPS For Your PC

Picking up a system starts with picking up a motherboard and processor and as we keep on adding the peripherals the power requirements of the PC keep increases with it. So, there is no perfect one size fits all kind of SMPS or PC Power Supply Unit, however there is a very clear methodology to choose a power supply that suits your system.

While most users pay much heed to the components like graphics card, RAM or any other component, there are very few who understand the importance of a great power supply.

So, for those of you who really understand the importance of the power supply. Here is a step by step guide on how to choose the best SMPS unit for your PC.

Manufacturer

First of all, lets be very clear about the brand value of the SMPS units. As, most people prefer RAM’s coming from Simmtronics or Corsair for their durability and reliability, there are SMPS brands which not only ensure their own durability but they protect every single peripheral attached to them. The top brands in SMPS units are Seasonic, Antec, Corsair and Coolermaster. However, a simple PC will need only the basic model of SMPS units from these brands.

Connectors

When selecting a SMPS, always ensure that it has the same family of connectors that your PC has. A mismatch will force you to buy another SMPS. Usually, the motherboard families supported by a SMPS are indicated on the box.

Right Output

There is a wide range of power out of the SMPS units, they come in all ratings from 200Watts to 1800 Watts. If you are building a simple PC, the best choice will be to buy a basic power unit. However, if you are buying a high end i5 or i7 PC, you should choose at least 600 Watts power supply. Extreme users like gamers should always buy a 1800watts power supply as their system keeps on upgrading from time to time.

Efficiency

Most SMPS units have their maximum efficiency when running with a load between 40 to 80 percent of their maximum load capacity. One should always ensure that the total load of the PC is in this range to ensure a high energy efficiency.

Ratings

Always buy a SMPS with a rating that says 80 Plus. There are categories in the 80 Plus SMPS units, but most of them have almost equivalent energy efficiency.

Rail

There is one thing to be noted while choosing a SMPS unit. There are certain low cost manufacturers which make single rail power supply to a large number of peripherals. Although there is no major impact on the system performance, it is recommended to never purchase such a SMPS. The major drawback of these systems is that if that one port which relays power to a large set of peripherals fails, all the components attached to it will stop working.

We can summarize that when choosing a SMPS unit, look for a good manufacturer. Then select an energy efficient model with a power rating which is twice the power rating of your system to ensure maximum energy efficiency while keeping space for future upgrades.

It is best to purchase PC Power Supply Unit from a top brand to avoid performance issues and to protect your priceless components from the wrath of a power surge.
