This makes the PSU extremely versatile and the perfect choice for present high-end systems and the ones to come.
THE NEW STANDARD OF POWER
For massive transient loads
Dark Power 13 offers 850W of continuous power with 4 independent 12V rails. Even if the graphics card demands excessive power for a short time: Dark Power 13 850W handles power excursions up to double its rated power with ease. This ensures reliable operation with the next generation of processors and graphics cards.
FRAMELESS SILENT WINGS FAN
Patented fan technology for virtually inaudible operation
The improved tripod-mounted be quiet! Silent Wings fan enables maximum airflow and a virtually inaudible operation. This is thanks to its unique, airflow-optimized fan blade design along with an advanced fluid-dynamic bearing. A 6-pole fan motor ultimately makes for less vibration, super-long life and minimal power consumption.
INNOVATIVE COOLING CONCEPT
For a longer lifespan
The split fan inlet of the Dark Power 13 850W is a custom-shaped funnel that increases airflow while reducing unwanted turbulence. The wire-free design inside allows the cool air to reach all components flawlessly which ultimately leads to a longer lifespan
READY FOR OVERCLOCKING
Pushing the performance of your PSU to the max
Dark Power 13 850W is particularly suitable for overclocking. The overclocking key gives you full overclocking control by manually switching between the default four 12V-rail mode and the alternative massive
single-rail operation.

JAPANESE 105° CAPACITORS
A testament to high quality
Only the best components are used in Dark Power 13 850W. That is why we have exclusively built high-quality Japanese capacitors into the PSU chassis. They are rated to 105°C which ensures stability, reliability, and a long operating life.
HIGHEST CONVENIENCE AND BEST CONNECTIVITY
Modular cables
Modular, sleeved cables of up to 120cm in length simplify component installation and reduce annoying clutter. This results in increased airflow and improved cooling in even the largest PC cases.
