Silent Pro 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. With up to 34A on the 12V rail, the Silent Pro series delivers where it counts and won't have any problems powering even with the most demanding SLI or CrossFire systems.
The Silent Pro 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.
