Super powerful and very efficient

Be Quiet’s Dark Power 12 series power supplies stand out for their high power, exceptional efficiency, quality of built-in components and quiet operation. So these power supplies are a brilliant choice for high-end gaming and professional computers.

After introducing the Dark Power 12 Pro series of high-end power supplies, Be Quiet introduced a slightly more affordable version of Dark Power 12. The latest Dark Power 12 series still offers the highest possible efficiency at 80 PLUS Titanium certification, and 750 models are available. 850 and 1000 W.


High-quality built-in components and a wire-free configuration on the DC side were used. All together, it results in a power supply that is primarily characterized by exceptional energy efficiency, which in practice leads to lower energy consumption and quieter operation.

Be Quiet has equipped the Dark Power 12 series with its proven 135 mm Silent wings fans with a maximum rotation speed of up to 1800 rpm. In actual operation, however, this fan is practically inaudible, until you load the power supply a little more seriously, but even then it is silent. The maximum power available to you with this model is 950 W, and it can continuously withstand a load of 850 W. Of course, this is a completely modular power supply design, which along the way brings many connectors with cables of decent length, which facilitates installation.


The Dark Power 12 series of power supplies is intended for everyone who needs a power supply of exceptional power and high energy efficiency, whether it is a high-end gaming computer or a professional machine. It should be borne in mind that each power supply is most efficient at a load between 40 to 50%. Also, today the latest high-end graphics cards can “pull” well over 300 W, so this high-quality power supply is definitely recommended for high-end gaming computers.

Be Quiet gives enthusiasts and overlockers complete control over the power supply itself using the OC quay, or PCI switch that switches power from the multi 12 V rail configuration to single rail 12 V mode.

Be Quiet’s Dark Power 12 is a prime quality power supply, the only serious drawback of which is the high price, so it will be available only to hardware enthusiasts with deeper pockets.
