Overview

Ultimate silence for exceptional efficiency


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

100% modular cable management


Thanks to fully modular cable management, cables that are not needed in the system are left out. As a result, the system always appears 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 while producing 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 Gold Certification


The be quiet! Straight Power 11 650W is 80PLUS Gold certified, with an efficiency of up to 93%. The main advantages are low power consumption and better, quieter cooling.

Wireless design inside the power supply


The Straight Power 11 650W operates wirelessly on the DC side inside the power supply. This results in improved cooling airflow and limited signal disturbance due to the elimination of cables. This innovative design also results in longer component life.

Innovative technologies and maximum compatibility for future systems


The use of LLC and Synchronous Rectifier (SR) technology provides improved operating stability and voltage regulation. The power supply is equipped with a DC/DC converter that significantly improves voltage quality and stability at high loads. These technologies ensure safe operation for the next generation of processors and graphics cards.


Main features:

  • Modular cable management for simplified, customised installation, reducing space requirements and improving ventilation and airflow
  • SilentWings 3 135mm fan with funnel-shaped fan opening in the power supply case
  • Wireless design on the DC side for improved cooling and component longevity

    Ultra quiet power supply even when coupled with an RTX 3070

    Perfect power supply, boot up on first installation. No noise, knowing that I'm in thermal on an RTX 3070 Aorus Master 8G. Everything works at tacket even in RayTracing or DLSS and without noise (or almost). Perfect power supply.

    A good alim that does the job

    I had a Power 10 that didn't last long, I hope this one will last a bit longer. It's not cheap to get a quality alim.

    Be Quiet makes the expert's mistake: a silly connection diagram is missing from the instructions. The length of each cable is detailed but that's not what matters to us, it's too late to change your mind anyway. Stop the blah-blah-blah and be more pragmatic, customer-oriented.

    The only thing missing is a pure SATA cable and not one mixed with those old 4-pin plugs, it's like going back ten or fifteen years. Just deliver an adapter, that's enough.

    The power supply is fully modular, so there shouldn't be any extra cable. It's too easy for Be Quiet to stick us with a double power cable for the graphics card as if everyone had two. Plus there are two cables like that. When the manual warns to use only the cables that come with the system... you don't use the single cable you had from the Power 10, because you might get a complaint from the service department. But that's stupid too.

    As an electronics specialist, I can tell you that it's well made, no problem there, you can feel that it's mastered. On the other hand, Be Quiet could take inspiration from Corsair for the packaging and presentation, which are top notch.

    I therefore withdraw 2 stars for these few peccadilloes that could easily be avoided: diagram, pure SATA cable and CG cable.
