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 between 501W and 800W. These units are aimed at systems with at least one dedicated graphics card, with some of the higher wattage units supporting SLI or Crossfire setups, and will leave some room for overclocking your hardware too. This wattage range is the most popular at OcUK, with efficiencies up to 80+ Platinum available from a variety of manufacturers, such as the popular SuperFlower Leadex series.
