It’s easy to overlook the power supply unit (PSU) when building your PC, but the PSU is one of the most critical components. 

It’s the PSU’s job to distribute power to all of the individual components within your PC, as well as protecting them in case of power surges. So, it’s critical that you buy the best quality power supply unit you can afford. Buy a poor quality unit and you run the risk of damaging your components. Not all PSUs are created equal!

A high-quality PSU will provide a more stable, reliable system, will reduce your energy bills and will generally be quiet too. 

Our range of power supply units includes 80 Plus Gold rated models across form factors such as ATX, SFX, and TFX, from brands such as Corsair, Be Quiet!, Seasonic, EVGA and more.
