be quiet! Dark Power 12 750W, 80 PLUS Titanium efficiency, power supply, ATX, modular, virtually inaudible Silent Wings fan

Looks like I'm the first person to leave a review about the non-Pro Dark Power 12 series here, as it's very new. Although the two series are combined in the same Amazon listing, they are different, and even made by different OEMs. The Pro version has a digital platform, and the non-Pro is analog.The power supply is very nice: looks good, everything is machined and finished well, the cables are safely thick yet flexible enough for routing, stealth black in color. I like that the fan is always on, as it continues cooling the various internal components without being audible at low to medium loads--and even high loads it is quiet. At initial power-up or waking from sleep, the fan very briefly spins up so you know it's working, and then slows down to low speed where you can't hear it.By default the power supply is in multi-rail mode. If you do not install the jumper or the switch, it will stay in multi-rail mode, which is advisable for over-current protection for your components. I did not install my jumper cable and switch; left them in the box.There is quiet and uniform electrical noise from the PSU that can be heard from about 1-2 feet away in a silent room when the PSU is out of the computer case. Once the PSU is in the case or at 4+ feet away outside the case, it's completely inaudible. I've had no audible coil whine yet with the PSU or my graphics card. Basically I never hear the PSU at all, except that initial brief (maybe 1 second long) fan spin up at the start.For anyone worried about the power switch still providing power to RGB lights on the motherboard as has been reported for DPP12--the non-Pro version does not do this, I have tested it. Flipping the power switch to O, no power is provided to the motherboard. Any lights that are on dim and turn off within about 1-2 seconds (once the capacitors in the PSU are drained of accumulated charge.)All in all, I'm very satisfied with this power supply. High efficiency, super quiet, great over-current protection with multi-rail design, and the reviews have been great for it with very low voltage ripple and deviation values. So far A+ for noise characteristics at Cybenetics, only 18.92dBa average noise output; awaiting a full review to be posted.

Great quality product for cost! Looks great in my desktop!

It's working.It's quiet.See you in ten years when I need another.

Where to start?It looks good but that is where it ends for me, I don't care about looks, I need an effecient & functional device on the inside.'Product conception, design and quality control in Germany' Does not translate well to something still made in China. They go on and on in their marketing about such great filtering. BS Marketing is a better statement.Coil whine, and extreme EMI line noise that puts a cheap no-name brand's millivolts reading to shame right out of the box!Perhaps I got a bad unit, but seeing something like this at this level (80+ Titanium) makes me not trust their lower end platnium line now, and that is probably why they only offer a 5 year warranty on those units.Sound engineers may need to steer clear. Ignore the A tier PSU list and do your own measurements and research.Be Quiet! More like GTFO!
