SilverStone TX-G TFX Spec and Price in the United States

80 Plus Gold500WTFX

TFX at 500W and 700W, which is unusual: the format normally tops out around 300W because there is no room for the heatsinks. These two reach gold efficiency in a 175mm-deep, 85mm-wide chassis cooled by a single 80mm fan, with fixed cables. They exist for slim prebuilt desktops whose owners want a real graphics card, and for anyone replacing an OEM TFX unit that has died. SilverStone covers the TFX family for three years.
