After successfully revolutionizing the HTPC and SFF market segments with innovative case designs, SilverStone engineers did not rest on their laurels but developed a truly meaningful power supply with a compact form factor for these markets: the ST45SF. The new SFX can be used not only with SFX cases but also with smaller ATX cases thanks to an included adapter. Despite its small dimensions, the ST45SF impresses with functionality that was previously reserved for the elite class of ATX power supplies – such as 80+ Bronze efficiency, temperature-controlled fan, 50 °C / 40 °C temperature rating, and extreme reliability: perfectly suited for continuous operation. Expert-appreciated features – such as a separate +12 V rail and 8/6-pin PCI-E connectors for seamless support of multi-GPU systems – complete the offering. For SFF users and for SilverStone, the ST45SF is more than just an upgrade component; it is an important milestone in the DIY desktop computer space.

V3.0 is aimed at systems that require higher output power of +12 V and quieter operation, such as gaming PCs and home systems.
