be quiet! Straight Power CM BQT E9-CM-680W

Computer source be quiet! Straight Power E9 CM offers detachable wiring through which simplifies the organization of the space within the casing and improves the flow of air. It features a top 135 mm fan SilentWings, with the help of which ensure a perfectly quiet operation and long life. Custom fan blades has specifically adapted to generate a minimum of noise, which also supports several advanced bearings FDB (fluid dynamic bearing) with copper core and a high-quality motor. Of course there is also automatic speed control according to the load current and temperature source. Another advantage of the resources of four strong and stable +12 V branches, which together can deliver up to 55 A.
Straight Power E9 CM 680 W premium meets 80PLUS Gold certification thanks to which you have secured at 20-100% utilization efficiency in excess of eighty-seven percent. Also meets the ErP directive and in combination with compatible motherboards in standby mode consumes less than 0.3 W. Despite the ostensible 680W power supply is also capable of peak load up to 750 W, so you do not have to worry about overloading, as is the case with some generic models. There is also a comprehensive system of providing feed itself and supplied components. Add to this the use of premium components, including high-quality capacitors marked up to 105 ° C and you have the ideal resource for demanding users.
