Introduction and Features
Compact 550W ATX PSU with Platinum level efficiency
Back by popular demand – today we are taking a detailed look at SilverStone’s new Strider Platinum Series 550W power supply. Not everyone needs or wants a high-capacity power supply and it is nice to see a medium range 550W unit with 80 Plus Platinum efficiency certification. Last month we looked at the Strider Platinum 850W unit and found it to be a very good power supply. In this review we are going to see if the 550W unit can live up to the expectations set by its big brother (tight voltage regulation, low AC ripple, high efficiency and quiet operation).
The Strider Platinum Series currently includes four compact models: the ST55F-PT (550W), ST65F-PT (650W), ST75F-PT (750W) and ST85F-PT (850W), which SilverStone claims are the smallest fully modular ATX power supplies with 80 Plus Platinum efficiency on the market. The chassis measures 140mm (5.5”) deep.
All of the Strider Platinum Series PSUs are designed to provide quiet, reliable operation. The 120mm cooling fan incorporates a Fluid Dynamic Bearing (FDB) and an intelligent fan control permits fanless operation at low power. The overall performance is optimized with tight voltage regulation and low AC ripple on the DC outputs. And the unit comes backed by a 5-year warranty.

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.”
