All All All

FSP Hydro X series power supplies are 80 PLUS Gold certified, unique ventilation hole design and built with premium components, to provide excellent cooling and quiet performance. With all Japan-made e-cap., they’re providing extremely stability and reliability. Custom DC-DC module offers supreme efficiency and high system compatibility. FSP Hydro X series is a great choice for who is seeking for a PSU with high performance, low energy loss and high reliability.


Hotcore Fan Control Design

Hotcore 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 hotcore 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.

DC-DC Module Design

Both of +3.3V and +5V DC-DC module combined +12V SR circuit offers supreme efficiency, voltage stability, and high system compatibility especially in cross regulation (unbalance load) mode.
