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 true 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℃ temperature rating, and reliability for 24/7 operation. Enthusiasts oriented features are also present with single +12V rail and 8pin/6pin 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.
