Compact SFX power supply with 80 PLUS bronze efficiency and powerful 37.5A single rail
With the SFX POWER 3 power supply, be quiet! to the compact SFX form factor. be quiet! uses a compact but quiet 80 mm fan with temperature-dependent control. The result is a powerful SFX power supply with a continuous output of 450 watts and a strong 12 V single rail with 37.5 A. Thanks to the SFX format, the SFX POWER 3 is primarily intended for mini cases, but still stands out stands out thanks to its extensive range of connections and offers good performance with minimal dimensions.

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

Instead of a multiple split 12 V line, this version has a powerful single rail with 37.5 A and offers various protection functions such as OCP (overcurrent protection), OPP (overload protection), OVP (overvoltage protection), UVP (undervoltage protection) and SCP ( Short circuit protection). The individually pluggable connections illustrate the performance of the power supply: In addition to 20+4-pin and 4+4-pin ATX/EPS connectors, there are also two 6+2-pin PCI Express connectors and three SATA connectors Disposal. Two 4-pin Molex connectors and a floppy connector are available for peripheral devices such as HDDs.
