FSP Group Hydro X

FSP Hydro X series is 80 PLUS Gold certified. Its unique ventilation hole design and premium-built components provide excellent cooling and quiet performance. With all Japan-made e-cap, it provides extreme stability and reliability. Custom DC-DC module offers supreme efficiency and high system compatibility. FSP Hydro X series is a great choice for those seeking a PSU with high performance, low energy loss, and high reliability.

Hot Core Fan Control Design

Hot Core Fan Control adjusts its speed precisely to provide optimal cooling which contributed to the thermometer to be designed into the hottest transformer and measure the hot core temperature on the first line.

Lower Power Consumption, Fewer Heat Emission

RDS (on) MOSFET is commonly used in electronics, and selected 2.8 ~ 1.4 mini-ohm grade. Hydro X is designed to use very low RDS (on) MOSFET, 0.85 mini-ohm for 550W/650W and 1.2 mini-ohm for 450W PSU, which is different from others, to reduce power loss and cool down component for reliability.

FSP Group Hydro X Extremely Tight Voltage Regulation

Extremely Tight Voltage Regulation

Custom VR(Variable Resistor) design to control the balanced point of +12V rail to make sure the output voltage regulation is under +/- 1% under any load change.

FSP Group Hydro X Eco-Minion IC Inside For Low Standby Power Consumption

Eco-Minion IC Inside For Low Standby Power Consumption

The functions of PC is always powered by the +5Vsb rail when the PC is in sleep or idle modes. Eco-Minion Controller can enhance overall performance of +5Vsb and efficiency to reach about 82.5% compared to 75% in general when load is about 1A.

FSP Group Hydro X Custom Soft Start Design

Custom Soft Start Design

The inrush current may hurt PSU when powered on. Hydro X features with custom power guard design to restrain switch-on surge for keeping PSU in safe.

FSP Group Hydro X Power Conversion Optimization

Power Conversion Optimization

Experienced design of shorter circuit among active PFC,LLC and secondary SR stages saves energy during power conversion and optimize EMI solution.
