The be quiet! Dark Power 12 850W offers 80 PLUS Titanium efficiency and a virtually inaudible frameless fan concept for flawless cooling.80 PLUS Titanium efficiency (up to 95.6%)Patented frameless Silent Wings fan for virtually inaudible operationRevolutionary full-mesh PSU front with redesigned funnel shape air inlet upholds the high air circulation abilitiesOverclocking key switches between four 12V rails and one massive 12V railModular cable management for maximum convenienceActive Rectifier + full bridge LLC technology provides unmatched signal stability and extremely high power efficiencyTen-year manufacturers warranty80 PLUS TITANIUM CERTIFIEDThe highest efficiency certificate availableDark 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 FANPatented fan technology for virtually inaudible operationThe 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 CONCEPTFor a longer lifespanThe 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 OVERCLOCKINGPushing the performance of your PSU to the maxDark 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 CONNECTIVITYModular cablesThe 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 TOPOLOGYState-of-the-art technology for extremely high power efficiencyWith 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 CAPACITORSA testament to high qualityOnly 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 105C which ensures stability, reliability and a long operating life.Model: DARK POWER 12 850WContinuous power (W): 850Peak power (W): 950Form factor ATX 12V: Version 2.52Form factor EPS 12V: Version 2.92Modular Cable management: yesTopology: Active Rectifier + Full bridge + LLC + SR + DC/DCWire-free design (DC-side): yesVoltage (Vac): 100 - 240Frequency (Hz): 50 - 60Input current (A): 13 / 7PFC: activePower factor at 100% load: >0.97Compliant to Intel C6/C7: yesPower consumption in standby (W):
