Our bestselling QTechnology Ultra-Quiet PSUs are the perfect choice for the vast majority of PCs and will give astounding results at a great price! Many professional audio workstation manufacturers are now using these units in their systems. Whether you are building your own studio PC, or you simply want to maintain a quiet home environment, the QTechnology PSUs really do deliver.
Building on the success of their earlier power supplies, QTechnology have made available three ultra quiet large-fan PSUs, rated at 360, 400 and 460 watts. They have an integrated 120 mm fan which provides a similar level of airflow to PSUs equipped with 80mm fans, but because the fan is larger in diameter it spins much more slowly. Therefore it is even quieter!

Instead of the fan being located at the back of the PSU, the 120 mm fan is on the underside (assuming you have a tower system), such that it sits adjacent to the CPU cooler. Because of this, the power supply not only runs quietly, but also assists in reducing the temperature of the processor and the ambient case temperature. Warm air is expelled through the large grille area on the rear of the power supply. These power supplies are exceptionally quiet, even when the loading and therefore temperature of the unit increases.
PLEASE NOTE - It has come to our attention that another company called "Q-Tec" has recently entered the market and is causing confusion by offering low cost PSUs in competition with QTechnology. Please be certain that neither QTechnology nor Quiet PC have any connection whatsoever with Q-Tec. We know several instances of customer being disappointed with the quality and noise level of Q-Tec PSUs only to find out later that the product they had bought was not made by QTechnology. If you are not buying directly from Quiet PC, please make sure you know what you are buying, and if the price seems too good to be true, it probably is! To add further to the confusion, we now find that there is a third company calling themselves Qtech who have started offering pre-built PCs. Again, our position is that we have no association with them.
All QTechnology power supplies come with a full 24 months manufacturers warranty.
