Semi-Passive Power Supplies


ASUS ROG THOR 850W 80 Plus Platinum II Modular Power Supply

Experience the perfect blend of silence and performance with a Semi-Passive power supply from Overclockers UK. These innovative PSUs are designed to provide virtually silent operation while ensuring optimal power delivery. Operating in fanless mode for lower loads, they offer complete silence. When the power demand increases, typically around 50% load, the fan kicks in to maintain cooling, whilst remaining whisper quiet.
