Final Thoughts and Conclusions
The SilverStone ST45SF is a good SFX form factor power supply.  It has many of the features that you would expect from larger ATX enthusiast PSUs like a painted chassis and sleeved cables. The power supply delivered good voltage regulation with good efficiency and maintained relatively clean outputs across a wide range of loads. The ST45SF also comes with both EPS12V and PCI-E connectors, which typically aren’t found on a small SFX form factor PSU. If you are in the market for a solid 450W PSU for a Micro ATX Media Center or Home Theater PC build, the SilverStone ST45SF deserves a very close look!

The SilverStone ST45SF power supply is currently available and sells for $80 USD.
