Overview

The ultimate in quietness for outstanding performance

The be quiet! Straight Power 11 modular power supply offers quiet operation without compromising on quality. Certified 80PLUS Platinum, it offers excellent energy efficiency. An ideal choice for quiet configurations, multi-GPU configurations, multimedia systems and systems for 3D photo/video applications.

Thanks to its fully modular management, the Straight Power 11 Platinum 's cables that serve no purpose in the system are left out. As a result, the system always looks very tidy. Due to the less cluttered layout of the system, the air flow is more fluid, which means less noise and heat inside the housing. In addition, installation is much easier.

SilentWings 3 fan

The high-end SilentWings 3 fan delivers superior airflow with very little noise. Thanks to its unique and optimised blade design, durable dynamic fluid bearing system and 6-pole motor, this fan eliminates operating noise, with the added bonus of minimal energy consumption and a very long service life. In addition, the funnel-shaped fan opening allows for increased airflow resulting in higher cooling performance.

80PLUS Platinum Certification

The be quiet! Straight Power 11 Platinum is 80+ Platinum certified, with a maximum efficiency of 93.7% to 94.1% depending on the model. The main advantages are low power consumption and better cooled, quieter operation.

Wireless design inside the power supply

The Straight Power 11 Platinum power supply operates wirelessly on the DC side inside the power supply unit. This results in improved cooling airflow and limited signal disruption due to the elimination of cables. This innovative design also results in longer component life.

    4.5/5 if I could rate like this!

    I was a bit worried that I wouldn't be able to plug it into my PC but in the end it was more fear than harm.
    The modular system is welcome, as well as the 1000 watts to finally manage to run Star Citizen without shut down problems. The only downside is that the cables are a bit stiff, which doesn't make installation any easier. But apart from that, it's great.

    Good functionality but design.....

    Okay platinum, 1000w okay okay it does its job,
    But damn the design, we are on big stiff cables surrounded by a black braid and doubled (so normal if you have cables not connected in your tower!),

    If you're looking for functionality yes, if you're looking for a clean tower with a bit of design, this is not the place to look....
