Better, Quieter, More Reliable Builds

It’s not easy being a system integrator in today’s competitive PC computing environment. Your customers demand—and deserve!—more, while you want the best price-for-performance available. be quiet! understands that, which is why we made the new System Power 7 300W.

Offering the best possible combination of power, quietness, features and efficiency, the System Power 7 300W gives the SI a big advantage, with worry free compatibility, maximum 12V power, and rock-solid voltages. It is 80PLUS® Bronze certified, and lets you build cost-effective systems with superior performance—a key differentiator in these days of carbon copy low price PSUs.

  • Class-leading quietness with 120mm cooling fan; annoying high-frequency noise in particular is reduced
  • 300 Watts of continuous power provide extensive power reserves for those times the PC really needs it all
  • More 12V power than other SI-class power supplies increases power stability, supports bigger system builds
  • 80PLUS Bronze certification and up to 87% power conversion efficiency for greener systems
  • Extensive compatibility with latest specifications, including Intel C6/C7, ErP 2014 and Energy Star 6.0
  • German product conception, design and quality control

 

Feature Details

Quiet Operation

  • Installed 120mm fan provides class-leading quietness
  • High frequency noise is reduced under all load conditions
 

Engineering

  • Better signal stability and power efficiency than typical SI-class PSUs
  • Full suite of top safety protections defends against over-currents, over- and under-voltages, short circuits, overheating and overloads, thus safeguarding your valuable components
  • Two large +12V rails improve power signal stability

Energy Efficiency

  • 80PLUS Bronze certification
  • Very high efficiency (up to 87%) means PC draws less power from the mains to do its work
  • Saving power means your customers can save on operating expense, but it also means less waste heat, less cooling required, and overall quieter operation
  • Standby drain of less than 0.25 Watts
  • Meets Energy Star 6.0 guidelines
  • Fulfills ErP 2014 guidelines
  • Zero Load design supports Intel’s Deep Power Down C6/C7 mode

 

Maximum Compatibility and Convenience

  • PSU supports up to 9 connectors for large system builds
  • Connectors are compatible with older components as well as those still on the drawing board
  • P4+P4 plug supports most mainboard types
  • Clearly labelled plugs and clever accessories promote simple installation

     

Outstanding Service and Support

  • 3 year manufacturer's warranty
  • Quick support is available via our international hotline, Mondays to Fridays from 0900 to 1730, German local time

 

“System Power is the entry to silent PC building, which still offers up to 80PLUS® Gold efficiency. With System Power we offer you everything you need for a reliable and cost-efficient operation.”
