Description

The be quiet! TFX Power 3 is a 300 W power supply unit in black, with TFX form factor and dimensions of 85 x 65 x 175 mm (width x height x depth) that fit into compact cases. Its weight of 1.1 kg and its design make it suitable for desktop systems with limited space. It incorporates active power factor correction, which contributes to efficient use of energy from the mains. It supports an input frequency of 50/60 Hz and an input current of 4 A at 110 V and 2 A at 220 V. The total power of 300 W is distributed between the 12 V rails, with two channels of 13 A each, and the 5 V and 3.3 V rails, both at 18 A. The 5 Vsb rail offers 3 A and the -12 V rail, 0.3 A. It includes protections against overcurrent, overvoltage, overvoltage, short circuit and undervoltage. The 20+4 pin ATX connector facilitates installation on motherboards compatible with this power supply format.
