A Detailed Look
The SilverStone Platinum Series 550W power supply enclosure is painted with a satin black finish and trimmed with white logo and nameplate. The compact chassis measures 140mm (5.5”) deep. The back panel includes an AC receptacle, master power On-Off switch and an open honey-comb grill.
The power supply uses a Globe Fan 120mm fan for cooling. The fan (S1202512L) is rated for 0.18A at 12 VDC and features a fluid dynamic bearing bearing for long life and quiet operation. The ST55F-PT power supply features an intelligent fan controller that allows semi-fanless operation. The fan does not start spinning until the power supply reaches at least a 20% load.
The front panel on the 550W PSU incorporates nine modular cable connectors, all nicely labelled and color coded.
All of the modular cables are flat ribbon-style to assist with neat cable routing and to help maximize airflow.
SilverStone uses remote voltage sensing on the ST55-PT to help insure tight load regulation. You can see the remote sense wires attached to the main 24-pin ATX cable in the photo below.
Under the Hood
Here are a few pictures showing the layout and components inside the Platinum Series 550W power supply. SilverStone is using High Power as the OEM for the Platinum Series. The overall layout, soldering, and build quality all look very good.
The power supply features a modern circuit design to deliver high efficiency and uses DC-to-DC converters to produce the +3.3V and +5V rails from the +12V output.
All of capacitors used inside the PSU are Japanese made with a good mix of electrolytic and solid polymer caps used throughout. The main primary electrolytic capacitor is made by Rubycon and rated for 470uF, 400V and 105°C.
Silverstone is knocking it
Silverstone is knocking it out of the park it seems with their power supplies lately. How do the reliability of the Rubycon caps compare to Nippon ones I wonder?

They compare very favorably to each other in the opinion of the reviewers at jonnyguru.com
Rubycon are high-quality,
Rubycon are high-quality, Japanese made capacitors that are in the same catagory as Nippon Chemi-con and Hitachi.
Wow, even though this one’s
Wow, even though this one’s 550W, sheer components and looks-wise this feels more like a Corsair from the AX times.
Nice PSU. can PCper verify
Nice PSU. can PCper verify that Silverstone continue to use a 1:1 pinout setup? custom sleever worry…
I believe the answer to your
I believe the answer to your question is yes. SilverStone typically uses the same connector/cable configuration on the majority of their modular power supplies. You can buy custom cable sets from them that work with most of their PSUs. The connector on the PSU end usually has the same pin count as the device end (8-pins on both ends of the 8-pin EPS cables, etc.).
