PSU up to 500 Watts

Power Supplies - The heart of every computer. Often overlooked and not given much thought when purchased, the power supply is one of the most important parts of your PC. Overclockers UK know that buying a reliable and good quality PSU is the key to a stable PC, which is why we offer a vast range of units from leading manufacturers such as SuperFlower, Seasonic, Cougar, EVGA, Corsair and be quiet!

In this section you will find all our PSU units with a wattage up to 500W. These units are best aimed at a relatively low powered to mid range system, with either integrated graphics or a mid range graphics card. They are also ideal for anyone who wants a more value orientated system build without skimping on the quality. We also have a good range of specialist units such as SFX, TFX and fanless units in this section.
