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.

This week, a very small package came was dropped off on my doorstep by FedEx. At first I thought it was more Gloria Jean's coffee for the Keurig coffee maker, but it turns out that SilverStone's latest SFX power supply was inside of this package.SFX power supplies are used in MicroATX and

Needed this to replace a failed P/S in a mini-server case. 450w from a P/S this size is really impressive. It's a bit overrated for the application but the other choices would not work correctly due to their dual rail design.

A great little PSU for powerful yet small builds. Comes with enough connectors to connect anything you'd ever want to inside something like an ITX case. PM took off over 1/4 of the price, making this pretty affordable for what you get.
If ever I needed another PSU for an ITX build, I likely wouldn't look anywhere other than this.
got this to power a simple but compact itx system with two hdd's and a 5450 works great stays quiet uses way less space with shorter cables which every one who's built in a lian li q08 will appreciate. I'll try to use these in all my future small form factor builds.
This is the right fit for a mATX case with a SFF power supply. I bought this to replace the noisy power supply that came with the case. Very hard to find replacement SFF power supplies especially one that is 450w.
