The Hydro G Pro Series power supplies feature 12VHPWR Connectors and utilize ATX3.0 with PCIe 5.0 technology for highly efficient performance. Its fully modular design simplifies installation and allows you to use only the cables you need, for a neater and cleaner build. The Fluid Dynamic Bearing (FDB) fan and Japanese E-capacitors together ensure higher reliability and lower noise. The FSP Hydro G Pro chassis is also covered with conformal coatings to guarantee reliable performance in a harsh environment. It features a server-grade design with copper bars joined to the mainboard and daughter board, this increases conversion efficiency. Its 5V standby circuit also provides a stable 2.5A output, enabling high conversation efficiency. A new heat dissipation design conducts heat through a thermal pad on the bottom of the power supply, transforming the PSU chassis into a heat sink for cooler system airflow. To save power it also comes with an Eco switch, when the Eco switch is turned on, the fan won't operate until the load is above 30%.
