ECO Switch, Quieter and Longer Lasting Fan

The Hydro PTM PRO series offers an Eco Switch that allows the PSU to operate quieter and uses up less power consumption. When the power supply is equal to or less than 30% load, the power supply enters a silent state and the fan is turned off.

Hydro PTM Pro

The HYDRO PTM PRO series comes with a FDB fan and an intelligent 0dBA function to reduce noise and has a longer lasting life span.
