The SilverStone TX400x Gold is a compact TFX design power supply unit, which with its 400-watt power is primarily designed for small, space-saving computer cases. The power supply has 80 PLUS Gold certification, which ensures high efficiency and low heat generation during operation.

The device is equipped with active PFC power factor correction, and its quiet operation is ensured by a single 80 mm fan. Its connectors include 1 x 24-pin ATX12V 2.x, 1 x 4+4-pin 12V, 2 x 4-pin 5.25-inch, 2 x 6+2-pin video card connectors, and 6 x SATA power connectors, so it is also suitable for powering two PCIe graphics cards.

The power supply has comprehensive protection functions: over-current protection (OCP), over-voltage protection (OVP), under-voltage protection (UVP), overload protection (OLP/OPP), short-circuit protection (SCP) and over-temperature protection (OTP), which together ensure the safe operation of the system and the power supply.

Available in black, due to its compact dimensions, it is especially recommended for users building in small, ITX or TFX compatible houses.
