    Be Quiet! Dark Power Pro 11 1200W PSU

    Legendary Silence, Cutting Edge Performance

    It is a fact of the modern world that high technology requires constant refinement and unending improvement — and that is even truer for those who would be leaders. Dark Power Pro power supplies are renowned as the world’s quietest and most efficient high-performance PSUs. The Dark Power Pro 11 1200W model takes that a step further with a power conversion topology that delivers 80PLUS® Platinum performance, add to that an unparalleled array of enhancements that augment this unit’s compatibility, convenience of use, reliability, and safety, and the result is the most technologically-advanced power supply be quiet! has ever built.
    • 80PLUS® Platinum certification and up to 94% power conversion efficiency
