Power Supply

When building your PC, one thing you should not compromise on is the quality of your power supply unit (PSU). The power supply unit is usually the last part of building your PC, and the decision comes after you have already considered what will be included. 

The PSU is a very important component, especially if you want the right amount of power for your system. Here are some tips to help you choose the right PSU.

  1. Calculate wattage

The first thing you should consider when buying a PSU is its wattage. You should weigh the wattage requirement of your PC components and ensure the PSU can accommodate it. Some PC components like graphics cards and the CPU will require a lot of power to run smoothly. If these components use the highest wattage, you still have to consider the amount of power other components will require. 

If your PC is underpowered, it won’t run smoothly. Most manufacturers provide an estimate of the power needed to run most of their parts. It will be easy to calculate so you can decide the total wattage your PSU should come with. When calculating the wattage, bear in mind that the power supply unit should always exceed the power requirement of your PC.

  1. 80 Plus Rating System

One of the things you will notice when browsing for a power supply unit is the 80 Plus rating. This rating shows how well the power supply unit converts power from your source to a lower voltage needed for the operation of your PC’s components.

Power supply units with the 80 Plus rating don’t have much power wastage. Also, the rating will guarantee that you don’t get more than 20% energy waste. There are different categories of the 80 Plus rating — White, Bronze, Gold, Platinum, and Titanium. The white is primary, while gold is what most users go for. Unless you are building a gaming PC, you may not need the platinum and titanium power supply units.

  1. Choose Your Rails

Another thing you should consider when getting PSUs is the rails. They can come specified as  +12V rails. What this means is the number of paths that channel the power supply to the components. A rail is described as a printed circuit board that usually draws power through its pathway. 

There are several types, the single rail or multi-rails. The multi-rails can distribute power across many paths, while the single rail only has one pathway. The single rail ensures that every component in your PC gets the right amount of power. It feeds full power from its single pathway to every other component it is connected to. 

However, the only drawback with using the single rail is that it puts your hardware at risk when there is a power surge. Multi-rails, on the other hand, can handle power surges. It has an inbuilt over current and short current in each rail that protects the PC components.

  1. Consider The Pin Connectors

Your PSU should have all the right connectors. They usually come in three types, 6-pin, 8-pin, and 6+2 pin cables. These pin cables can be used to connect to a 6 or 8-pin input.

You need to consider components that consume a lot of power, like the graphics card and so your motherboard. The motherboard may need a 20 to 24-pin connector.  This is why you should attend to all other components before you buy power supply units. After you sort these out, you’d be able to check what power supply you have to get.

  1. Get Modular PSUs

The modularity of your PSU makes it easy to prevent any cluster. This way, you can easily remove or detach the connecting cables. There are non-modular power supply units that come with a lot of cables that you may not have need. You don’t need any cable clutter, which can prevent airflow. Also, getting a modular power supply unit is a more portable option.
