Be Quiet! enters the market with a new series of power supply units, entitled Pure Power 9 CM. The lineup includes models of 400 W, 500 W, 600 W, and 700 W power. All of them boast the implementation of Active Clamp + SR topology with high-quality hardware base. Besides, the manufacturer decided to ditch group mechanism of voltage stabilization; this promoted for more efficiency which index achieves 91%.High efficiency level allowed Pure Power 9 CM units to receive 80Plus Silver certificate. The 12V bus is divided into two lines with the maximal load capacity. Cooling process is attached to a single low-noise 120-mm fan, based on rifle bearing (100 thousand hours MTBF). Its maximal rotational speed varies within 1060-1680 RPM range.
To continue, Be Quiet! has incorporated into the models all possible security mechanisms, including OPP, SCP, UVP, OCP, and others. The units come with an additional Surge Absorber filter that protects the circuitry from voltage surges. …
ECS decided to tackle the problem of sameness, developing a new motherboard on the basis of Intel NM70 Express chips. The implementation exactly of these chips makes the board a pioneer in its product class. ECS NM70-I is designed in mini-ITX form factor and houses Intel Celeron 847/807 CPU. The latter consumes only 17W of power to add the board power-efficient properties. Such approach to layout secures a harmonious balance between performance parameters and price ranges, and is an ideal match for compact PC systems.
