Be Quiet! Releases Dark Power Pro 10 - its Quietest Active-Cooled PSU

Be quiet!, market leader for power supplies in Germany for six years in a row*, announced today the release of its new high end line of PC power supply units (PSUs) called Dark Power Pro 10. The flagship series now uses state-of-the-art power conversion and cooling technologies along with other design enhancements to be the quietest and most energy efficient models in the company’s 12 year history. The range features six models all with a modular cable management system and power outputs from 550 to 1200 Watts.

Now with 80 PLUS Platinum Certification
The all-new power conversion circuitry topology features Full Bridge (high power models) and Half Bridge (lower power models) LLC resonant converter and DC-to-DC voltage stepdown along with Synchronous Rectifying to confer unmatched power efficiency and signal stability. Efficiencies range up to 94% and 80 PLUS Platinum certification, the highest independent energy certification on the market, depending on the model.

SilentWings and engineering details enable ultra-silent concept
Dark Power Pro 10 series all use be quiet!’s renowned SilentWings fan; the key feature in a completely redesigned cooling system with a new and custom made 135 mm fan. This fan features a fluid dynamic bearing (FDB) which provides a 300,000 hour lifespan and makes it virtually inaudible. Furthermore using very high quality fans enhances PSU reliability as fan failure is by far the most common failure mode for power supplies. Silent operation is additionally achieved via painstaking optimizations which have minimized all forms of noise—acoustic, electrical and mechanical. In addition the fan grille design and mounting were both fine tuned during design for quietness.

The result is astonishingly low noise levels. For example, the 850 Watt model produces less than 12 dB(A) of noise all the way up to 90% of full load, the 550Watt less than 14 dB(A) even at full load. Additionally up to four case fans can be attached to and independently controlled by PSU circuitry exclusive for this function to further minimize system noise.

Overclocking key: Single- and Multi-Rail operation
Resolving a long-time dispute amongst PC enthusiasts, be quiet! offers the only power supply which lets you choose between multi- or single-rail 12 V mode. A quick flip of the switch turns Dark Power Pro 10 from factory default four rail setting to high performance single rail mode.

“Dark Power Pro 10 offers users a truly no compromise PSU with the highest levels of performance, energy efficiency and is astonishingly silent” said Scott Richards, Global Brand Director for be quiet!. “Our German design team has put it all in this product line. Unsurpassed quality of build and performance along with uniquely quiet operation… precisely the attributes that have made us the long-time sales leader in our home market of Germany.”

Being a no compromise design, Dark Power Pro 10 also features 105° C Japanese capacitors along with a five year warranty. Six versions will be available: 550, 650, 750, 850, 1000 and 1200 Watts. Suggested prices start at 135.00 Euro for 550 W version and go up to 279.00 Euro for 1200 Watts of power. Dark Power Pro 10 is shipping now.

When I was reading this article I think that all models is with 80+Platinum. Only one sentence showed truth:

depending on the model.
Only one model (850W) is 80+Platinum certified, all others is only 80+Gold :D

"Quietest Active-Cooled PSU" Ok, fair enough.
How many noisy good quality PSUs do you guys know?

I mean, some of the most quietest graphics cards are louder then some decent PSUs.

Well like you said, most good quality PSUs have good fans so they're not loud. However, fans don't last forever, I had to replace the fan in my PSU since the one installed started to reach the end of its life.

They call them passive cooled. I don't think anyone was comparing fan-less graphics cards with fan-less PSUs though, maybe I should read the thread to be more clear on things.

Actually they are mainly a German distributor. The units sold in UK are fewer in variety and tend to cost more. I ordered one last year for a friend and I found a lot more models in Germany.

I also got an ASUS ENGT430 that is whisper-quiet active cooled vga...
My point is: why arguing about a silent psu that is less noisy than others at full load?

Most types, the other end is three pin.

The power supply doesn't care about the RPM it will just supply 12,7 or 5 volts to the vans attached to it.

Not sure if this model PSU does it but my one used to leave the fans plugged into running for 30 seconds after the system shut down ( at 5v) just to get rid any excess heat : ]

Please, mention one passive cooled graphics card that needs 850 watt power supply.
Want passive? you'll probably wont need more then the seasonic X460 unit.

I'm running BeQuiet-PSUs for many years now - really great and VERY silent units! Can recommend them to every owner of a silent, watercooled system. In that case every little frazzle of noise counts.

They use 2 OEM for this series.

The 550W, 650W, and 750W models are manufactured by FSP, while the 850W, 1000W, and 1200W are manufactured by Seasonic.
