Features
80 PLUS® TITANIUM CERTIFIED
The highest efficiency certificate available
Dark Power 12 850W is certified with 80 PLUS Titanium and an energy efficiency rating of up to 95.6%. This provides lots of benefits for your high-end system, including less power consumption and an overall cooler and quieter operation. The standby drain is below 0.1 watts.
FRAMELESS SILENT WINGS FAN
Patented fan technology for virtually inaudible operation
The be quiet! Silent Wings fan mounted on a tripod 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 and 6-pole fan motor 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 12 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 12 850W is particularly suitable for overclocking, thanks to its strong and stable 12V rails. 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.
HIGHEST CONVENIENCE AND BEST CONNECTIVITY
Modular cables
The maximum utility provided by modular sleeved cables of up to 120cm simplifies component installation and reduces annoying clutter. This results in increased airflow and improved cooling in even the largest PC cases.
WORLD CLASS TOPOLOGY
State-of-the-art technology for extremely high power efficiency
With an active rectifier and full bridge LLC technology Dark Power 12 850W offers some of the most advanced technologies available, resulting in higher efficiency, better regulation and lower ripple noise for an incomparably stable operation.
JAPANESE 105° CAPACITORS
A testament to high quality
Only the best components are used in Dark Power 12 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.
