Since my old Be quiet! 450 watt power supply was now a bit outdated I have now ordered this here and now installed in my Silent Maxx Big tower case. The processing of the power supply is excellent. Everything is clear and makes a high quality impression. The supplied cables are - at least for my needs - thought out and just right. The length of the cable, as in some tests - for housing in which you mounted the power supply down - was chalked too small, is perfectly adequate for my case. On the contrary, the cable would be even longer would just hang out again annoying in the area. Thanks to the successful cable management the housing interior looks remarkably tidy from - a real improvement over my old power supply configuration. The fan is still quieter than quiet in my old Be! - And with a closed (soundproofed) housing barely perceptible - and I am what something really reached critical! Anyone who is looking for a high-quality and silent PSU of this class, I can only recommend this device.
