Introduction and Features

750W Platinum certified ATX PSU is only 140mm deep

SilverStone recently introduced a new line of Platinum certified PC power supplies, which they claim are the world’s smallest 80 Plus Platinum, full-modular ATX power supplies. The new Strider Platinum Series currently includes three models, the ST55F-PT (550W), ST65F-PT (650W) and ST75F-PT (750W). All of the Strider Platinum Series PSUs are designed to provide quiet, reliable operation in a small package. The cooling fan incorporates Fluid Dynamic Bearings (FDB) for quiet-reliable operation and an intelligent fan control permits fanless operation at low power. While the typical 750W power supply enclosure measures 160mm (6.3”) deep, the Strider Platinum Series are housed in a 140mm chassis (5.5”).

The main focus of this review will be on the 750W ST75F-PT model, but the good folks at SilverStone also sent along one of the 550W (ST55F-PT) models so we will include test results for both units for comparison. It’s always nice to receive two different units in the same series to help confirm operation and performance parameters.

Here is what SilverStone has to say about the new Strider Platinum Series PSUs:  "As desktop computers continue to advance toward ever more efficient and smaller designs, SilverStone is helping to drive the efficiency movement by releasing the Strider Platinum Series of power supplies. Created to be the smallest fully modular ATX power supplies with 80 Plus Platinum efficiency, they are also incredibly quiet with the ability to run in fanless mode. If the loading condition is below 20%, the fan in the power supply can remain off for silent operation during idle or low powered computing activities. Other great features inherited from previous Strider series includes ±3% regulation, powerful single +12V rail, 24/7 continuous power output, and multiple PCI-E cables. For those looking to build highly efficient systems in small footprints, the Strider Platinum is definitely the best choice.
