Introduction

With power supplies, many people believe that bigger is better but in truth most rigs will never draw above 500W including my i7 rig at full tilt. So should we be buying smaller wattage units that are not only cheaper but also generally quieter? Yes, the battle between noise and performance once again rages in the PSU market and Cooler Master’s Pro M500 unit hopes to be the quietest we’ve tested yet. Featuring a 135mm fan, transferring heat from hot spots and fin type design, Cooler Master’s unit can certainly talk the talk but can it walk the walk? Let’s find out.

A brief Introduction from Cooler Master

“The Silent Pro M series is a new range of single rail power supplies from Cooler Master that’s addressing a growing market demand for powerful single rail PSU’s. With up to 50A on the 12V rail, the Silent Pro series delivers where it counts and won’t have any problems powering even the most demanding SLI
The Silent Pro M series is also the first power supply from Cooler Master to feature flat modular cables for improved airflow and cable management. It also comes with anti-vibration silicon pads to remove possible vibrations from the PSU to reverberate into the case.”
