A Detailed Look
The FSP Hydro G 850W power supply enclosure is painted satin black with light gray lettering. It features color coordinated labels for the side panels to suit your particular builds color scheme. The PSU comes with blue labels attached but you can choose to alternately apply red or green ones (adhesive backed).
The 850W unit measures 170mm (6.7”) deep. The back panel includes an On-Off switch, AC receptacle and large asymmetrical fan grill openings for good exhaust airflow.
The power supply uses a 135mm Power Logic fan (PLA13525S12M) that incorporates a fluid dynamic bearing for quiet operation and long, reliable life. The fan is rated for up to 0.40A and 2000 rpm at 12 VDC. The Hydro G 850W power supply uses FSP’s intelligent fan speed controller that allows silent fan-less operation at low power.
The front panel includes eleven connectors for the modular cables, all nicely labeled.
The Hydro G 850W power supply comes with a basic assortment of ten fully modular cables for easy installation and clean builds. All of the cables are the flat ribbon-style. AS we noted before, notably missing was a second EPS 8-pin cable/connector. And even though not everyone needs one of these, at the 850W power level we would expect one to be included.
Under the Hood
Here are a few pictures showing the layout and components inside the Hydro G 850W power supply. Of course FSP Group Inc. is the OEM! The layout appears a bit cluttered but the soldering, component selection and build quality are excellent.
FSP is using a modern, high-performance LLC, Synchronous Rectification power conversion design along with DC-to-DC voltage regulators located on a daughter card to provide tight voltage regulation and high efficiency.
All of the Japanese made electrolytic capacitors are rated for 105°C operation and the two primary filter caps are made by Nippon Chemi-Con and rated for 330 uF, 420V, and 105°C. The numerous solid polymer caps are supplied by Teapo.
