This time we measured the sound pressure level and found out, that this PSU has a common fan speed regulation. The RPMs are tolerable up to 50-80% load. Beyond that point, this PSU is no more silent than competing solutions, but we should keep in mind that most GPUs are louder while gaming so the results are fine. Note the difference the power grid makes in terms of efficiency. 115VAC means higher current and more stress for all power supplies, while 230VAC shows a worse power factor at all loads. Nevertheless, 0.823-0.988 PFC is still good and most users will find 87% efficiency more than sufficient.
All the rails fall clearly within ATX specifications. They start slightly over the target voltage and end with results close to -2%. Since this PSU has four 12V outputs, we selected the worst rail for the tables (which is our standard procedure). +12V shows the best regulation, and will have no trouble with higher voltages. Both smaller rails have less than 30mV ripple and noise, while +12V reached 75mV.

This org is dedicated to the demise of our society through false reporting ofso called ecological facts. It is an example of a modern "wolf in sheep's
clothing". The donation is to WWF is sufficient enough for me to not ever purchase anything from IN Win.

I'd feel better if it was for Wounded Warrior Foundation/Projectshin0bi272 - Wednesday, June 6, 2012 - link

Or the World-Wide Wrestling Federation. Can you imagine getting body slammed every time you littered? The world would get a lot cleaner, a lot quicker.Finally - Thursday, June 7, 2012 - link
...where hopelessly over-dimensioned power supplies start at 650W.Seriously. I can't remember when AT did a review of anything below this margin...
Enthusiast-shmusiast. Most people have 1 mid-range GPU and something along the lines of an Phenom II X955 / i5-2500K - mine never draws more than 240W tops...
Why the hell would I be interested in 1200W power supplies, when my usual power draw is less than 10% of that?

THIS is a power supply I'm interested in:Bequiet E9-400W, Gold-rated, perfectly silent cooling.

i don't want to found the WWF.So you can keep this.

perhaps by found you meant fund?Marburg U - Wednesday, June 6, 2012 - link
yes, sorry. ;-)
