Quiet Power Supplies

Quiet Power Supply

We feature today's top quiet power supplies (quiet PSUs), known not just for their extreme silence, but also for ultimate reliability. We build all of our quiet PCs with the same power supplies we sell and personally support every Quiet PC we produce.

Fanless Power Supplies

We also carry fanless power supplies for absolute silence in a quiet power supply. Kingwin and Silverstone both have great fanless power supplies, which provide a reasonable amount of power, while maintaining manageable heat levels for your quiet PC. As is always the case, if choosing a fanless PSU for your quiet PC project, you will want to pay close attention to heat dissipation and airflow in your PC.


A quiet power supply is one of the first computer components to pay attention to when trying to quiet your PC. Checkout out our article on building a Quiet PC for advice on what other priorities are important in building a quiet computer or quieting your existing PC.

Build A Quiet PC

If building a fanless PC, you'll want to pay attention to how fanless PCs are designed. Fanless PCs have a tendency to overheat unless designed correctly. If using a fanless power supply, you will need to pay special attention to purchasing a reliable power supply which doesn't overheat. The only fanless PSU we can recommend is the Silverstonetek Fanless PSU.
