Fan Performance Chart Graphic

Silent & Intelligent Fan

With Auto Fan Speed Control, the power supply's 135mm fan turns slowly at low temperatures, reducing power consumption and fan noise to near silence. When temperatures increase, fan speed will also increase. This decreases the odds of over-heating, extends the fan's life span and reduces energy consumption.

A semi-modular PSU design comes with only the essential cables pre-attached. This allows for some customization of additional cables, plus reduced clutter and better airflow compared to non-modular PSUs within your computer case or system.
