Compact SFX power supply with 80 PLUS bronze efficiency and powerful 25 A single rail
With the SFX POWER 3 power supply unit, be quiet! on the compact SFX form factor. be quiet! installed a compact but quiet 80 mm fan with temperature-dependent control. The result is a powerful SFX power supply with a continuous output of 300 watts and a strong 12 V single rail with 25 A. Thanks to the SFX format, the SFX POWER 3 is primarily intended for mini housings, but it still stands out extensive connection arsenal and offers good performance with minimal dimensions.

The high efficiency of the power supply of an average of 82% to 85% was awarded the 80 PLUS bronze certificate and ensures that only relatively little electrical energy is converted into heat.

Instead of a multiple split 12 V line, this version has a powerful single rail with 25 A and offers various protective functions such as OCP (overcurrent protection), OPP (overload protection), OVP (overvoltage protection), UVP (undervoltage protection) and SCP (short circuit protection) . The individually attachable connections illustrate the power of the power supply unit: In addition to 20 + 4-pin and 4-pin ATX / EPS plugs, there is also a 6 + 2-pin PCI Express connection and three SATA plugs. Two 4-pin Molex connectors and a floppy connector are available for peripheral devices such as HDDs.
