PC POWER SUPPLIES

A power supply unit (or PSU) is an essential piece to the puzzle when it comes to getting your systems operational and maintaining stable long-term outputs. While other components within your setups may get more attention due to their roles once your systems begin operations, they will never be able to get to that point without the support of an adequate PSU. Here at Box, we stock everything you need for the best custom PC build experience, as well as the tools to help DIY enthusiasts make the necessary alterations to their builds, including an extensive range of power supply units to fit all kinds of builds and budgets.

What to Look for In A PC Power Supply Unit

Some of the most important things to consider when selecting the right PSU are wattage output, cable type and efficiency rating. Ensuring you have sufficient output potential to actually power your components is essential in your search. Certain systems like high-end gaming PCs will require more power outputs than a more basic mini-PC, so understanding what your current build needs should be step one.

The 80 Plus rating of your PSU is important to know as it determines the efficiency and power consumption rate of your power delivery. Typically, anything from 80 Plus Silver and onwards should handle your basic computing demands, but those looking to air on the side of caution may want to invest in an 80 Plus Gold model.

Cable type is important as it determines how you are able to actually integrate your PSU into your PC case. Which type of connection you end up going for can also be directly influenced by your level of experience when it comes to the PC build and maintenance process. Those already very experienced may find no issue opting for a fully-modular cable connection, where you can pick and choose freely which cables you end up utilising. However, the more novice builders may find it safer to stick with the non-modular or semi-modular cable type as they offer a more straightforward installation process.
