Cooler Master Silent Pro M 700W @ Tech-Reviews.co.uk
 

Noise in computer systems is an ever growing problem - one which many enthusiasts strive to deal with. A Power supply is often thought as quite a quiet component of the hardware which makes your PC. However, turn off all of your running fans and just listen to the noise from the PSU; you'll be pleasantly surprised. For this reason, Cooler Master has developed the Silent Pro which boasts a sound level of less than 16dBA.
