SilverStone TX300 Spec and Price in the United States
A TFX unit, which is a format most comparison sites skip entirely: 85mm wide and 175mm deep, shaped for slim office desktops and small cases that will take neither an ATX nor an SFX power supply. It is 80 PLUS Bronze, cooled by an 80mm fan from 18 dBA, and has fixed rather than modular cables — there is no room for a connector panel. A single PCIe 6-pin means it powers a small graphics card at most. Three-year warranty.
Prices exclude sales tax.
