It's unusual to be excited by a power supply, but...,
Verified Purchase(What is this?)
This review is from: Be Quiet Dark Power Pro 10 550W PSU (Accessory)
...this is the business. My CPU and GPU combination probably pulls around 280W at full load, so even with a few drives and peripherals attached, I'm not likely to need more than 400W at any one time. Some people mistakenly believe that the more wattage, the better, but high-efficiency PSUs tend to be a their best when working at 50% upwards, so I'll be getting efficiency benefits (lower power draw, lower temperatures) from this even when I'm not using it for any heavy lifting.
The main reason I bought this was because I need quiet components, and this PSU excels in this regard. I've arranged it to vent into the case (many prefer to exhaust the warm air outwards) so that it 'stacks' the airflow along with the existing CPU cooler and case fans - basically it's all venting straight up through the topmost 200mm case fan. If it ran hot, then this would might be a problem, but this model seems to be cool at all times. My CPU idles at 25C (thanks to the Dark Rock 2 CPU cooler), and rarely exceeds 50C at full-bore.
The icing on the cake is the built-in fan controller, which allows you to plug any system fans (even non-PWM models) directly into the PSU, allowing it to control them based on case temperature. Which it does extremely well, given me a system that's now quiet enough for me to hear the faint buzzing noise coming from one of my LCD monitors.
Like I said - it's not normal to get excited by a power supply. But this one's an exception.
