be quiet SYSTEM POWER 7 300W BN140

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
Quick support is available via our international hotline, Mondays to Fridays from 0900 to 1730, German local time
