SilverStone Strider Titanium ST1500-TI PSU Review

Teardown & Component Analysis

Before proceeding with this page we strongly encourage you to a look at our PSUs 101 article, which provides valuable information about PSUs and their operation, allowing you to better understand the components we're about to discuss. Our main tools for disassembling PSUs are a Thermaltronics soldering and rework station and a Hakko FR-300 desoldering gun. Finally, for the identification of tiny parts we use an Andonstar HDMI digital microscope.

This looks to be a new platform from Enhance Electronics, featuring a full bridge topology along with an LLC resonant converter. On the secondary side, a couple of DC-DC converters are used to generate the minor rails, and the +12V rail is regulated by a huge number of Infineon FETs.

We also notice many polymer filtering caps on the secondary side and only few electrolytic ones. Polymer caps are preferred because they can withstand much tougher conditions and last longer. Of course, electrolytic caps still have to be used in PSUs due to their increased capacity. On top of that, their impedance helps avoid unwanted oscillations in some cases. In short, then, you can replace most electrolytic caps on a PSU's secondary side with polymer ones, but you cannot get rid of them all.

The following footage shows the ST1500-TI's internals.

    This is the season to be mining. Its winter and those that do mine should be doing so to keep the house warm during peak winter season if not to earn extra cash to go under the tree then to at least help lower their heating bill. -evil grin- actually im trying to promote people to buy more graphics cards because when all this fake coin crashes it will be raining graphics cards cheap everywhere!

    Yeah, when it crashes - who knows, maybe it only crashes in 10 years, maybe it wont? Dont be so cynical

    I had not noticed the absence of a power switch, someone could have sent an uncompleted one, otherwise looks great.

    No power switch? Who will buy this?
