Semi-Passive PSUs


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

Equip your gaming PC with a semi-passive PSU from Overclockers UK, and get both exceptional power delivery and near silent operation. With a vast range of power supplies from manufacturers including Phanteks, Seasonic, Corsair, and be quiet! semi-passive PSUs are highly efficient. This allows them to operate with just passive cooling until they are under a heavy load. Once they reach this level of power delivery, the fan will spin up to actively cool the PSU. Many power supplies feature exceptional fan designs, which aid them in still being whisper quiet even when maximising their cooling.
