DARK POWER PRO 11
1200WNo Compromise Silence and Performance
Dark Power Pro 11 1200W is be quiet!’s most advanced PSU ever. With 1200W of continuously available power and an overclocking key that switches between four-rail and single-rail operation, it has sufficient reserves to support any multi-GPU or multi-CPU system you could want to build. be quiet!’s virtually inaudible Silent Wings 3 fan and an unparalleled array of noise-reducing enhancements make it the quietest PSU in its category, perfect for powerful applications that nevertheless need significant quietness. And its full bridge power topology earns it one of the highest power efficiency certification available — 80 PLUS® Platinum.
Characteristics
80 PLUS® PLATINUM CERTIFIED
One of the highest efficiency certificates availableDark Power Pro 11 1200W is certified with 80 PLUS Platinum and an energy efficiency rating of up to 94%. 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.
SILENT WINGS 3 FAN
Equipped with the best fan technology be quiet! offersThe decoupled be quiet! Silent Wings 3 135mm fan provides 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.
FUNNEL-SHAPED FAN OPENING
Higher cooling performanceThe fan inlet of the Dark Power Pro 11 1200W is funnel shaped. This causes an increased throughput of air, which results inhigher cooling performance.
READY FOR OVERCLOCKING
Pushing the performance of your PSU to the maxDark Power Pro 11 1200W is particularly suitable for overclocking, thanks to its strong and stable 12V-rails. The overclocking key empowers you with full control for overclocking by manual switching between the default four 12V-rail mode and the alternative massive single-rail operation.
EQUIPPED WITH HIGH-END FEATURES
Build powerful multi-GPU systems with confidenceDark Power Pro 11 offers 1200W of continuous power with four independent 12V-rails for excellent signal stability and nine PCI express connectors for multi-GPU systems. Up to four case fans can be connected to, and regulated by the PSU.
MAXIMUM CONVENIENCE
Professional modular cable managementThe maximum utility afforded by extra-long sleeved cables of up to 120cm and modular cable management simplifies component installation and reduces annoying clutter. This succeeds in increasing the airflow and improving the cooling in even the largest PC cases.
STATE-OF-THE-ART TECHNOLOGIES
Rock-steady signal stability and efficiencyExperience the most technologically advanced power supply be quiet! has ever built! Using an advanced full bridge, LLC and Synchronous Rectifier (SR) technology it provides unmatched signal stability and unbeatable power efficiency. It is also equipped with DC-to-DC conversion for tight voltage regulation, even under heavy cross-loading conditions. This ensures reliable operation for the next generation of processors and graphics cards.
JAPANESE 105° CAPACITORS
A testament to high qualityOnly the best components are used in Dark Power Pro 11 1200W. That is why we have built exclusively high-quality Japanese capacitors into the PSU chassis. They are rated to 105°C which ensures stability, reliability and a long operating life.
