Introduction

Power Supplies were once the most overlooked component of a computer. A power supply was simply a power supply and nothing more. Lately however, more and more people are realizing the benefits that a high quality PSU can bring to your system. When shopping for a PSU, there are a number of things you should be looking for: power, quality and noise (or lack thereof!).

Today's systems require power. NVIDIA recommends the use of at least a 480W power supply with their latest GeForce 6800 Ultra! However, the vast majority of computers out there are able to survive perfectly fine on a 300W PSU (if even). However, supplying enough power isn't the only thing you should be looking for. The quality and construction is also a major issue if you want to ensure the longevity of the PSU as well as the components it powers. Last, but definitely not least, is the noise factor. If you are trying to quiet down your computer, and especially if you demand utter silence like myself, choosing the right power supply can be vital. I can't even count how many power supplies I have come across that just beg to be thrown out a window due to the noise they emit.

Zalman, who is well known for producing high performance, low noise heat-sinks and water cooling products, has taken notice of the lack of low noise power supplies in the market. Regardless of Zalman's reputation, I was still skeptical when I heard about their Noiseless Switching Power Supplies. Many other products that I have come across that were either labeled "Silent," "No Noise" or "Quiet" didn't fully live up to their name. However, let's not come to a conclusion before we actually take a look and do some testing. So read on, because this just may be the quiet power supply we have all been looking for.
