FSP Hydro G PRO 850W Power Supply Review

FSP are using a Protechnic Electric Fluid Dynamic fan to cool the Hydro G 850W supply. Model number MGA12012XF-025 (12V 0.52A). A small plastic flap with some small holes cut into it ensure the air flow hits specific parts of the unit to keep it cool.

Below - a High Resolution Gallery of the internal layout of the Power supply.

This FSP design incorporates a few small heatsinks across the board and is nicely laid out and the soldering standard is of a high standard. They are using a 3.3V and 5V DC-DC module design to help improve voltage regulation for all rails. We can see there is a new heat sink design for the 12V switching circuitry – which conducts the heat through a thermal pad on the bottom of the PCB – helping to improve cooling.

FSP are using Japanese caps throughout the design which is good to see. The Primary capacitor is 105c rated, by Nippon Chemi Con (KHS series) – rated 450V 680uF. I rate Nippon Chemi Con very highly – I have never seen one fail in the 15+ years I have been doing this.

The Hydro G PRO 850W power supply confirms to OCP, OVP, OPP, SCP and OTP protections and is rated to 100,000 hours MTBF.
