A Detailed Look
The SilverStone Platinum Series 1000W power supply enclosure is painted with a black hammer-tone finish and trimmed with a white logo and nameplate. The chassis measures 180mm (7.1”) deep. The back panel includes an AC receptacle, master power On-Off switch and an open honey-comb grill for good airflow.
The power supply uses a Hong Hua 140mm fan for cooling. The fan (HA1425H12B-Z) is rated for 0.50A at 12 VDC and features dual ball bearings for long life. The ST1000-PT power supply features an intelligent fan controller that allows semi-fanless operation. The fan does not start spinning until the power supply reaches approximately 40% load.
Included with the power supply is one of SilverStone’s own FF141 fan filters. The 140mm square dust filter incorporates magnets in the frame to hold it in place on steel chassis or it can be attached with screws.
The front panel on the 1000W PSU incorporates seventeen modular cable connectors, all nicely labelled and color coded. The power supply comes with little covers over most of the connectors. During installation, you can just uncover the connectors you need and leave any unused connectors covered for a clean look.
All of the modular cables are flat ribbon-style to assist with neat cable routing and to help maximize airflow.
Edit: One note of caution however. If you are not paying attention when you plug the modular cables into the PSU, it is possible to plug one of the 6-pin peripheral cables into either of the 8-pin EPS slots.
Under the Hood
Here are a few pictures showing the layout and components inside Platinum Series 1000W power supply. SilverStone is using Enhance Electronics as the OEM for the Platinum Series (ST1000-PT and ST1200-PT). The overall layout, soldering, and build quality all look very good.
The power supply features a modern circuit design to deliver very 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 high-quality with a good mix of electrolytic and solid polymer caps used throughout. For example, the two main primary capacitors are made by Nippon Chemi-Con (KMR) and rated for 390uF, 450V and 105°C each.
