SFX-300W
be quiet! SFX Power, 300 W, 100 - 240 V, 50 - 60 Hz, 2.5 - 4.5 A, +12V1,+12V2,+3.3V,+5V,+5Vsb,-12V, Active
Description
SFX Power are compact power supply units which reliably supply mini PCs and mediasystems with power. With the latest use of technology SFX Power meets the demands of a premium product and of course with the customary be quiet! quality low noise levels.
SFX Power provides sufficient power without compromising quality, stability and security. In developing the SFX Power great value was placed on the efficient use of energy regarding a high level of energy efficiency of up to 86%.
Areas of application
- Mini- and Mediasystems
- Classic office and web applications
Quiet operation using mature fan technology
- 80mm quality fan
- The RPMs on the fan are automatically governed based on the temperature
Power-conserving operation
- 80PLUS certification. The high efficiency of up to 86% reduces power dissipation (waste heat) and also saves power.
- Fulfils the requirements of the environmental and energy-savings Energy Star 4.0 * guidelines
- Low power consumption in stand-by mode (<1W).
- Fulfils the EuP guidelines
High stability
- Dual-rail operation with two independent 12V rails
High Compatibility
- Various connection options, with up to 8 connectors
- One PCIe connector for graphic cards (350W)
Top security and reliability
- Top protection for components against over/under currents, short circuits and overloads.
- German engineering and internationally tested safety, confirmed by recognised testing labs
Ideal for small- to mid-sized PC cases and systems
- Optimal cable sets with up to 50cm long cables
- All-in-one cable with the most common drive connectors
Service
- 2 years manufacturer's guarantee
- Quick support via our international hotline
