80 PLUS ® PLATINUM CERTIFIED

Dark Power Pro 11 550W is certified with 80PLUS ® 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 0.13 watts.

SILENT WINGS 3 FAN

The 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

The fan inlet of the Dark Power Pro 11 550W is funnel shaped. This causes an increased throughput of air, which results in higher cooling performance.

READY FOR OVERCLOCKING

Dark Power Pro 11 550W 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.
