“Scythe's debut in the power supply market features a built-in fan controller and ultra quiet fan, plus a fully modular connectivity system.”
Scythe's Kamariki 4 power supplies feature a fully modular cable connectivity system called "Plug-in". By having detachable power cables, you can remove the cables you don't need and avoid cluttering up the inside of your case with unnecessary wiring. This makes working on your PC much easier, as well as improving airflow. The Kamariki power supplies are available in four different wattages from 450W to 750W. Each PSU uses the famous Scythe Kaze Jyu 100 mm fan to ensure efficient cooling.
It is also possible to connect up to three case fans to the Intelligent Fan Cable Connector which automatically adjusts the fan speed of those fans according to the loading of the power supply. The case fans can be connected directly or via the supplied modular fan cable. In order to satisfy customer demands as well as the green IT movement, the Scythe Kamariki 4 PSU series fully conform to the 80Plus standard at 20/50/100% system load.

550W Modular x (4)

Bought this to replace another 'quiet psu' - the silence is deafening! When I walk in and nothing else (than my 24/7 PC) is on I don't hear it at ALL. Before it was drowned by the TV but now it is drowned by nothing. BUY THIS - it is absolutely amazing. (Oh, 3GHz AMD runs 150W, well inside this PSU's range - which no doubt helps too.)

I had emailed Andy (QuietPC) for a recommendation for a quiet PSU to go in my new machine intended for use in my studio. This Kamariki was his suggestion and what a difference it made. I already had a pretty quiet PSU, but it was still the noisiest part of the system. This Kamariki is so quiet, it may as well not be there. Superb product and the modular cabling has considerably tidied up the inside of the case.
Only one problem... I'm now going to have to spend some more hard-earned on silencing the hard disks I couldn't hear before I put this in ;-)

I agree with John Niven - whisper quiet, excellent selection of modular cables (and very shiny!) All I can hear now is the occasional hard disk access and the AMD stock fan on my phenom II (which isn't too bad).
FYI - from the packaging noise levels are 8.4 dBA up to c. 250W load then pretty much linear increase to 23 dBA at the full 550W.

I purchased this for its noise-level, with its modular power-cabling as a secondary issue. When it arrived I found a third issue - it's beautiful! In use it's whisper quiet (the AMD-supplied CPU fan makes more noise), and I wouldn't go back to a traditional PSU. The modular cabling is superb, and another reason I'd stick with this PSU. My case is opaque, but if any PSU made me buy a windowed-case it would be this one - it's so shiny!

This is so quiet you don't know it's there, and the modular cabling means you can achieve Zen-master cable tidying inside. Very highly recommended.
