Ultra high end 550W power supply from Cougar... Tecnical details & special features EXTREMELY HIGH EFFICIENCY Up to 89% of efficiency, compliant with 80-PLUS Bronze @115V efficiency requirement. DC-DC TECHNOLOGY (1000CMX/1200CMX) DC-DC technology provides highest efficiency, most stable performance, & perfect regulation (Regulation <3%). COMPATIBLE WITH LATEST PC-TECHNOLOGY Supports the newest specifications of ATX12V Created for usage with current & next-generation multi-core CPU platforms. SUPPORT MULTI-GPU TECHNOLOGY Support PCI Express 2.0 next-generation graphic card with 8 (6+2)pin PCI-E connector HIGHEST DURABLE & RELIABLE SOLID CAPS FOR 12V, 3.3V, 5V (1000CMX/1200CMX) The best solution for a High-End PSU by using solid caps for 12 Vs, 3.3V, 5V, solid caps provide highest efficiency, best reliability, & extend power lifespan. 105°C JAPANESE CAPACITORS COUGAR use highest durable 105°C Japanese capacitors provide uncompromised performance & reliability, delivering 4 times the lifespan of conventional 85°C rated capacitors. HDB (Hydro-Dynamic Bearing) 14cm FAN Advanced HDB (HYDRO-Dynamic Bearing) fan provide best lifespan & super silent performance. Temperature-controlled design adapts its rotating speed to the PSU temperature. Even on its highest rotating level the fan is still quiet enough to be barely noticeable. DYNAMIC DUAL 12V Automatic dynamic load distribution on DUAL 12V rail provide power separately to the GPU & the CPU. If you are not using all output lines, the PSU automatically reroutes needed power from unused lines. This improves the performance of the 12V lines considerably for systems with high-end graphic cards in SLI or Cross Fire mode and provides high voltage stability to keep components safe. FLEXIBLE CABLE MANAGEMENT The modular cables that reduce air friction help maximize airflow through the PC case. The modular design also simplifies installation as it allows unprecedented flexibility in using only those cables which are needed. COMPLIANT WITH LATEST EUROPEAN DIRECTIVE 2009/125/EC (Er P) SUPPORTS THE ENERGY STAR 5.0 Compatible with Energy star 5.0 computer system.
