The Silverstone ST45SF-G power supply is a special, small form factor power supply for some of Silverstone's ITX cases. It is very efficient, with an 80 PLUS Gold rating, but limited on wattage due to size. For an ITX-based system it should be plenty, though, as such computers can only fit one video card and a limited number of drives.

Please note that due to the smaller size of this PSU, it cannot be used in larger cases which are designed for full ATX power supplies.

William George (Product Development) Says:
This should be able to handle powering almost any single-GPU video card, but I would not recommend it for use with dual GPU cards. Of course, such cards would probably be too hot to put in a small chassis to begin with.
