Introduction & Packaging
Silverstone is one of the biggest PC component manufacturers in the world. Every year they launch a colossal amount of products that span a huge range of hardware and usage scenarios. They’ve got an ever-growing range of connectors, cables, fans, filters, I/O devices, chassis, coolers and more. Of course, the one that’s most important to us today is that they also make some of the industries best PSU hardware. Their new Strider Platinum ST55F-PT 550W really caught our interest, as not only does it pack 550W of power, it also has 80 Plus Platinum efficiency, fully module cables, high-quality components, and a hybrid/passive cooling feature, but it’s also incredibly compact for a PSU with these hardware specifications, making it a promising solution for compact system builds.
“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 include ±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.”
With a depth of just 140mm, this PSU should be extremely compatible with a very large selection of chassis products, including many of the very ergonomic chassis which Silverstone produce. With high-quality components that add excellent efficiency, voltage regulation and 24/7 operation, we have high expectation of what this PSU can do.
- Compact design with a depth of 140mm for easy integration
- High efficiency with 80 PLUS Platinum certification
- 100% modular cables
- 24/7 continuous power output with 40℃ operating temperature
- Class-leading single +12V rail
- Strict ±3% voltage regulation and low ripple & noise
- Ultra silent 120mm fan with intelligent semi-fanless operation
All the usual security features are here, as well as a good range of connectors, a good quality fan and more. So let’s jump in and take a closer look at what it has to offer.
The packaging is nicely designed, with all the main hardware specifications detailed on the box, as well as the quote “world’s smallest 80 Plus Platinum full-modular ATX power supplies.”
Around the back, more technical performance data that most people are likely to ever read, but it’s nice that Silverstone are catering to those who understand it all.
In the box, you’ll find the mains power cable, some velcro cable ties, some plastic cable ties, the mounting screws, as well as an in-depth user manual.
