Characteristics
- Up to 400 Watts of continuous power to ensure steady operation even when your PC meets an unexpectedly heavy load
- 80 PLUS® Bronze certification and up to 89% power conversion efficiency let you use the provided energy more efficiently and reduces your power bills
- Product conception, design and quality control in Germany
Energy Efficiency
- 80 PLUS Bronze certification independently verifies the high operating-efficiency (up to 89%) of this design
- Higher efficiency means cost savings, because your PC draws less power from the mains. It also means less wasted heat, less cooling required, and an overall quieter operation
- Standby drain of less than 0.25 watts
- Meets Energy Star 6.0 guidelines
- Fulfills ErP 2014 guidelines
- Zero Load design and support of Intel’s Deep Power Down C6/C7 mode
Engineering
- Use of the latest technology ensures premium performance and reliability
- Supports the latest Intel® and AMD™ CPUs
- Full suite of top safety protections defends against over-currents, over- and under-voltages, short circuits, and overloads, thus safeguarding your valuable components Low-Noise Operation
- An automatically temperature-regulated 80mm high-quality fan
- Assured balance between cooling performance and quiet operation
Highly Compatible and Convenient
- Sleeved cable lengths up to 50cm allow for improved cooling and are perfect for mini PC cases
- System features 9 connectors for flexible system builds
- Connectors are compatible with older components as well as those still on the drawing board
- PCIe connector supports discrete graphics card
- Clearly labeled plugs enable simple installation
Product Conception, Design and Quality Control in Germany
