Summary and conclusion
The be quiet! brand has my respect because it pays great attention to every power supply it makes. It doesn’t focus as much on high performance as Corsair does, for example, but cares more about noise performance. A 1-2 ei difference in overall performance may not be critical for most users, but 5-10 dBA less noise is most important, and I can feel it.
I worked with my first PSU load tester, the legendary Faganas, just a foot away from me, with all of its fans running at full speed and exceeding 50 dBA. I wouldn’t say I like a fan putting out more than 30 dBA for long, so I undervolted the CPU in my work PC to have the lowest possible thermal load. Silent computing has been trending for quite some time, and while you might think that the noise of the power supply is unimportant, keep in mind that it can have a significant impact on the overall system.
The overall performance is not on the top position despite the high efficiency of the device. However, this is not a bad or mediocre power supply, it’s just that the competition in this category is very strong and usually offers tighter load regulation, lower ripple and a generally higher overall performance on balance. However, that is now complaining at the very highest level, because the differences are not that big.
Full performance at 47°C ATX v3.0 and PCIe 5.0 capable Very good transient response at 12V High build quality Quiet operation Efficient Good APFC performance Sufficiently low power dissipation at 115V Low inrush current at 230V Satisfactory ripple suppression Long bypass time Long and accurate power ok signal Compatible with alternative power management mode (ALPM) Fully modular Numerous connections, including a 12VHPWR (600W) Sufficient spacing (150mm) between peripheral ports Frameless FDB fan Ten-year warranty |
OCP protection features need to be optimized Not competitive overall performance Load regulation should be stricter Not efficient 5VSB rail (230V) Only two 4-pin Molex connectors |
Many thanks to Aris, whose data I may and will continue to refer to in the future if such power supply tests are requested by readers.
