After successfully revolutionizing both HTPC and SFF market segments with innovative chassis designs, SilverStone engineers continue their push for advancement in these categories by releasing a truly upgrade-worthy small form-factor power supply: the ST45SF. This SFX unit is compatible not only with chassis that use SFX power supplies but also in smaller ATX chassis with the included adapter bracket.
Despite its small size, the ST45SF has features that one would expect from an elite ATX power supply - such as 80 PLUS Bronze level of efficiency, temperature controlled fan, 50-degree temperature rating, and reliability for 24/7 operation. Enthusiast-oriented features are also present with single +12V rail and 8-pin / 6-pin PCI-E connectors to fully support multi-GPU systems. For SFF users and for SilverStone, the ST45SF is more than just an upgrade - it is an important milestone for the DIY desktop computer.
80 PLUS Bronze certified to reduce wasted heat and save on electricity
Built-in 80mm fan has excellent airflow and low noise, perfect for quiet home or office use
Powerful single +12V rail design, perfect for future high-end component upgrade
Included SFX to ATX bracket for use in ATX case
Pros: The Silverstone ST45SF packs the power needed for a gaming Mini-ITX build while remaining efficient, quiet, and reliable. The fan inside the PSU has always remained whisper quiet even when pushed to it's upper limits. Silverstone provided long enough power leads to allow for connectivity of components on the other side of a Mini-ITX case. The ST45SF fits perfectly inside of the Silverstone FT03 Mini without having to sacrifice precious space otherwise used for a video card. The 80% plus power efficiency is icing on the cake!
Cons: This isn't a modular power supply. That being said, the modular variation of this power supply caused clearance issues inside of the Silverstone FT03 Mini case. The extra power connections were easy enough to bundle up and neatly tuck out of site.
Overall Review: Over the course of a year and a half, I've put this power supply through some serious gaming binges and it has withstood the abuse. It has powered two different generations of Nvidia graphics cards without any problems.
