Semi-passive Power Supplies

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!

Semi-Passive power supplies aim to offer the best of both worlds when it comes to silence and performance. They work by operating in a fanless mode up to a certain wattage load, allowing for completely silent operation. Once the unit hits the specified load (usually around 50%) the fan will spin up to cool the unit, although this is still barely audible. As these units become more efficient, the power supplies can operate at higher and higher loads without requiring the fan, leading to an extremely quiet experience. At OcUK we have a wide range of Semi-passive power supplies available, including the complete SuperFlower Leadex range, and selected EVGA SuperNova units.
