STRAIGHT POWER 10

400W

World Class Quiet and Efficiency

be quiet! Straight Power 10 400W provides a new level of silent performance for systems that demand whisper-quiet operation and efficiency without compromising on power quality.

Improved cooling with use of a 135mm SilentWings® 3 fan with an advanced fan frame ensures operation that is extraordinarily quiet.
Improved power circuit technology delivers 80PLUS® Gold power efficiency (up to 93%) and stability unmatched in its class.

Powerful GPU support and reliability enhanced by premium 105°C-rated parts make this PSU a ‘Best Choice’ whether you are building a new system or seeking a better, quieter replacement for an existing system

  • Virtually inaudible operation achieved through a broad array of meticulous optimizations, including use the of a be quiet! SilentWings® 3 135mm fan
  • SilentWings® 3 fan features an advanced fan frame, an airflow-optimized fan blade, fluid-dynamic bearing with copper core and a high-quality 6-pole motor for less vibration
  • The funnel-shaped fan opening of the PSU case is significant big and allows high airflow intake
  • 400 Watts of continuous power with stable four 12V-rail design
  • 80PLUS® Gold certification and up to 93% power conversion efficiency
  • Sleeved cable lengths for improved cooling and more attractive appearance
  • Product conception, design and quality control in Germany

Virtually Inaudible Operation

  • Installed SilentWings® 3 135mm fan includes a wide array of electronic and mechanical optimizations for best-of-class airflow with very low noise production, including:
    • unique airflow-optimized fan blade design reduces noise-generating fan turbulence
    • advanced fluid-dynamic bearing with copper core provides for greatly reduced operating noise and super-long life
    • 6-pole fan motor with high-quality IC controller reduces electrical noise, power consumption, and vibration. Lower starting voltage of the fan reduces significantly the starting fan speed and noise level at low load conditions
  • Funnel-shaped fan opening of the PSU case is significant big and allows high airflow intake
  • SilentWings® 3 fan is decoupled from the PSU body with special mount, further reducing transmission of vibration and noise
  • Optimized PSU airflow design generates superior cooling at lower fan speeds and reduces turbulence around components, thus allowing even quieter operation
  • Variable fan speed is optimally governed to strike the best balance between proper cooling and deep quietness


Energy Efficiency

  • 80PLUS® Gold certification independently verifies the extremely high operating efficiency (up to 93%) of this design
  • High efficiency means money savings, because your PC draws less power from the mains to do its work. This means less waste heat, less cooling required, and overall quieter operation
  • Standby drain of less than 0.25 Watts (</= 0.15W)
  • Meets Energy Star 6.0 guidelines
  • Fulfills ErP 2014 guidelines
  • Zero Load design supports Intel’s Deep Power Down C6 and C7 modes

 

Engineering

  • Improved integrated circuit power conversion design features Active Clamp and Synchronous Rectifier (SR) technology plus DC-to-DC voltage stepdown for amazing signal stability, voltage regulation (main output rails are </= 2%) and power efficiency
  • Premium quality capacitors rated to 105°C for maximum performance, reliability and operating life
  • Full suite of top safety protections defends against over-currents, over- and under-voltages, short circuits, overheating and overloads, thus safeguarding your valuable components
  • Three independent 12V-rails improve power signal stability

 

Maximum Compatibility and Convenience

  • Sleeved cable lengths up to 115cm allow for improved cooling and are perfect for large PC cases
  • Connectors are compatible with older components as well as those still on the drawing board
  • Individual P4 and P8 plugs on longer cables support all common mainboard types and allow routing behind motherboards for improved airflow
  • Two PCIe connectors for powerful multi-GPU configurations
  • Clearly labeled plugs and clever accessories promote simple installation

 

Outstanding Service and Support

  • 5-year manufacturer's warranty
  • Quick support is available via our international hotline, Mondays to Fridays from 9:00am to 5:30pm CET : +49 (0) 40-736 76 86 – 98
