Meet Pure Power 9 CM Top Series of PSUs from Be Quiet!

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. …

Asus to Start Shipping Radeon R9 290 DirectCU II OC Graphics Card

Next week Asus is going to start shipping its newest graphics card from Radeon R9 series. Codenamed Radeon R9 290 DirectCU II OC, it is based on an original PCB with black-and-red design and the incorporation of an exclusive DirectCU II cooling system. Plus, the availability of ‘OC’ in the codename implies the availability of factory overclocking.



Asus Radeon R9 290 DirectCU II OC takes GCN Hawaii core with 2816 stream processors as the basis. It operates at an overclocked 1000 MHz frequency. The model is equipped with 4 GB of GDDR5 memory (512-bit bus) that runs at an effective 5400 MHz frequency. Just for a comparison, etalon adapter from AMD runs at 947 MHz/ 5000 MHz for GPU/memory correspondingly.


DirectCU II cooler consists of a heatsink, four copper nickel-plated heatpipes (two of them feature 10 mm dimensions), and two high-performance fans: one ordinary and one CoolTech. The card receives power via 6+8-pin connectors and might require not less than 600 W PSU.
