Art.No. BN123




PC power supply for demanding customers
Are you looking for a power supply that's proven its worth many times over? A unit that can be used flexibly with mid-range and high-performance PC systems and that shines even when handling resource-heavy graphics applications, providing a reliable supply of efficient and stable power? If so, the STRAIGHT POWER series is for you – with or without modular cable management.
Whether you wish to integrate older components or are already thinking of the next generation – the extensive roster of features with unmistakably labelled plugs ensures optimal compatibility. And the Ultra Silent Concept from be quiet! ensures that the power supply always runs whisper-silent.
- Gaming and multimedia
- Power-hungry graphics applications
- Entertainment PCs
Areas of application
- Ultra Silent Concept with be quiet! SilentWings fan technology (registered with the German patent office): The variety of electronic and mechanical optimisations, such as FDB bearings with copper cores, flow-optimised fan blades and high-quality IC motor control lead to more silent running, best-of-class air flow and very low noise emission
- The RPMs on the 120mm fans are automatically governed based on the temperature
Extremely quiet operation using top fan technology
- The very high efficiency of up to 88% reduces power dissipation (waste heat) and also saves power, as attested by the 80PLUS BRONZE certification
- Fulfils the requirements of the environmental and energy-savings Energy Star 5.0 * guidelines
- Low power consumption in stand-by mode (<0.5 W)
- Fulfils the EuP guidelines
Highly economical operation
- Supports multiple GPU applications running in SLI and CrossFire configurations
- Highly stable multi-rail operation with up to four independent 12V rails
For multi-GPU applications
- Up to 27 connection options, ensuring a very high degree of compatibility, even for older components or those not yet developed
- Separate P4/P8 plugs for different mainboard types
- Up to four PCIe connections for graphic cards running in multiple card configurations (SLI and CrossFire)
Very high compatibility
- Modular cable management (CM models 680, 580, 480 W): The removable cable bundles make it easier to install components, provide a more orderly structure and promote better air circulation within the case.
- Clearly labelled plugs, 115cm coated cable and well-thought out accessories for simpler installation
Convenient Usage
- Top protection for components against over/under currents, short circuits, overheating and overloads
- German engineering and internationally tested safety, confirmed by recognised testing labs
- Full performance during 24/7 operation. Long service life of up to 100,000 hours.

Top security and reliability
- Up to 2 case fans can be connected to cool the case; these are then automatically regulated by the power supply depending on the temperature
System cooling
- 3 years manufacturer's guarantee
- Free on-site exchange service within first year (D, F)
