A Detailed Look
The SilverStone ST75F-GS V2.0 power supply enclosure features a matte black, scratch resistant finish. The ST75F-GS uses a Globe Fan 120mm fan (S1202512L) on the bottom for cooling that incorporates sleeve bearings. While sleeve bearings allow for very quiet operation they typically do not provide the same level of longevity as ball bearings do.
The fan speed is automatically controlled by the internal component temperature. It starts out slow and quiet and gradually ramps up in speed as the output power increases beyond 60% load.
The back panel includes an AC receptacle and master power On-Off power switch. The open honeycomb grill allows exhaust air to exit the power supply with minimal resistance and turbulence.
The front panel incorporates eight modular cable connectors, all nicely labeled. The two blue 8-pin connectors are for the PCI-E cables.
The SilverStone ST75F-GS power supply comes with a basic assortment of modular, cables and connectors. The cables are all a flat ribbon-style and black to help facilitate installation with a clean look. Some users may also be looking for a second 8-pin EPS cable/connector or six PCI-E connectors instead of the basic four at this power level.
Under the Hood
Here are a few pictures showing the layout and components inside the ST75F-GS power supply. SilverStone appears to be using High Power as the OEM for the ST75F-GS V2.0. The overall layout looks clean with good soldering on the PCBs.
The ST75F-GS uses one Rubycon electrolytic capacitors on the primary side, rated for 560uF, 400V, and 105°C. The secondary is populated with a mix of high-quality solid polymer and electrolytic caps.
The ST75F-GS power supply uses two DC-to-DC converters to create the +3.3V and +5V rails from +12V. The two VRM sections are located on a small daughter card (between the large black heatsink and colorful red-orange-yellow output wiring in the photo below).
