be quiet! SYSTEM POWER 7 450W 80PLUS SILVER (BN143)

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 450W.

Offering the best possible combination of power, quietness, features and efficiency, the System Power 7 450W gives the SI a big advantage, with worry free compatibility, maximum 12V power, and rock-solid voltages. It is 80PLUS® Silver 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.
- 450 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 Silver certification and up to 90% power conversion efficiency for greener systems.
- Extensive compatibility with latest specifications, including Intel C6, ErP 2013 and Energy Star 5.
- German product conception, design and quality control.
