be quiet! Announces Dark Power 12 Power Supply Series
be quiet! introduces the Dark Power 12 series. This high-end power supply series consists of three models with 750, 850, and 1000 watts.
They are positioned directly beneath the award-winning Dark Power Pro 12 series, starting at 1200 watts. Dark Power 12 features an extraordinary 80 PLUS Titanium certification, an advanced topology, and a proven cooling concept for the perfect balance between efficiency, performance, and silence. An Overclocking Key lets users combine the four 12 V rails into one with high power output, ideal for overclocked processors or graphics cards. be quiet! has combined these high-end technical specifications with fully modular black sleeved cables.
Dark Power 12 features 80 PLUS Titanium certification. be quiet! has achieved this high-efficiency factor by implementing the advanced "Active Rectifier + Full Bridge LLC + SR + DC-DC" topology and a wire-free interior design on the DC side. Unlike the Pro models, Dark Power 12 does not rely on digital regulation: the active rectifier helps its topology achieve a high efficiency rating on Titanium level. For maximum reliability and signal quality from the four 12 V rails, Dark Power 12 relies exclusively on premium components such as long-lasting Japanese 105°C capacitors.
Patented Silent Wings 135 mm fan for high air circulation and virtually inaudible operation
To make sure the high-end components in Dark Power 12 are optimally cooled even under extreme load, be quiet! has come up with an innovative method to integrate its award-winning Silent Wings 135 mm fan. The result is a patented frameless fan, placed directly under a full mesh grill, surrounded by a funnel-shaped air intake for optimal air circulation and best-in-class cooling. The fan has a low startup rotational speed. It operates virtually inaudibly, negating the need to constantly stop and start the fan as such semi-passive solutions often place unnecessary stress on the fan components.
Extensive feature set
As a successor to the popular Dark Power Pro 11 and lower-wattage option to the Dark Power Pro 12 series, many beloved features from both series carry over into Dark Power 12, including the Overclocking Key. This switch allows users to change the power supply from multi-rail mode to single-rail mode with the flick of a button or an optional jumper, increasing the PSU's stability under extreme overclocking conditions. To match the high-quality components inside the power supply unit, be quiet! has created a steel housing that elevates this power supply series's appearance and offers a complete set of modular, black-sleeved cables. Thanks to its high component quality and the innovative cooling design, be quiet! offers a 10-year manufacturer's warranty.
Pricing:
- $199.90 / £205.99 / €214.90 (750W)
- $239,90 / £239.99 / €249,90 (850W)
- $279,90 / £269.99 / €279,90 (1000W)

Proper question is: MTBF?
Did your 10 PCs had reasonable of time to even reach 1/4 of MTBF?
Like, if I buy 120 of PSUs in 10 years. And keep each only for one month. There will be no opportunity for components to die from prolonged stress.
So, what's minimum/maximum/mean time you kept each of those 10 PSUs in each PC over course of 10 year? And what was usual load in percent of maximum rated load of Given PSU?
It is quite easy to answer as all of them are used even today. Half of them mainly models up to 550W as office/home pcs. Doing 12h/day of online time.
Another half is gaming PCs. Two of my own, working heavy under gaming and(hashcalc)..
680W dark power ( if i recall model correctly). Didn't manage to keep up ryzen 5600x + r6800. Being 8y old after 3 gaming and overclocked rigs. Seems good record to me

Thanks.
Does that mean that those 550W have usual load around 65~125W?
And then rest would be loaded around 250~550W, which is reasonable load.
But all are quite low power PSUs. Are any of them magical 6x 12V Rails with merge to 1 rail "Overclocking" Function? Or similar design?
Often simple products work much better and fail less often than complex over-engineered products.

I replaced that 680W with 750W model , they both have 4 rails -. You have to use separate rails for GPU if you want stability ...The other weaker models are loaded no more than 100W i'd say but they are online alot, and fans are as silent as they were brand new which is good record in my opinion . I had PSUs from Corsair , Thermaltake , like 6 different models and half of them died . Over 10 different Bequiet psus and none died . Maybe just luck but i think they are high quality.

How are these better than series 11?
I can highly recommend bequiet psus. As i had over 10 pcs over last 10 years and none died, all same accustis as brand new. Maybe i was lucky but they seem high quality to me
