Chieftec Showcases Five New PSUs from Navitas Series

Chieftec, one of the largest German hardware manufacturers, has recently introduced a new series of power supply units, codenamed Navitas. The series is represented by 5 models: GPM-650C with 650W nominal power, GPM-750C with 750W nominal power, GPM-850C with 850W nominal power, GPM-1000C with 1000W nominal power, and GPM-1250C with 1250W nominal power correspondingly. All the products have won 80Plus Gold certificate, due to more than 90% efficiency in the high workloads.



Chieftec Navitas PSUs correspond to ATX12V v2.3 standard and support Intel Core 4th gen. processors that require little current strength on +12V rail in sleep mode. The models also support active power-factor correction option to provide for the maximal stability during operation. They are equipped with a composite cable system and a single +12V rail, estimated for the maximal current from 54 A to 104 A (this index depends on the unit’s power).


All five units are cooled down by 140 mm fans with PWM …

AMD Readies a Pair of Power-Efficient Desktop Processors

The Internet community is engrossed in a lively debate about the upcoming release of two new Richland desktop processors from AMD. The company has not made any official claims yet, however MSI marked the pair as an appropriate match for some of its new motherboards. Those Richland CPUs, which has already been launched by AMD, proved to be rather power-efficient, featuring 65 W and 100 W TDP level. But new entries – AMD A8-6500T and AMD A10-6700T – are thought to receive 45 W TDP package.



Upon the whole, AMD Richland processors position themselves as affordable, efficient and reliable solutions that can be employed for the assembling of systems with moderate or heightened demands. Some CPU models might be even used for the assembling of gaming systems. However, along with high performance, Richland processors are rather power-efficient; this makes them an ideal choice for home-based and corporate-class PC platforms.


As for the announced models, their specifications are …

Universal CPU Cooler Zalman CNPS9900DF Review

Zalman keeps on developing high-end cooling systems with a radial arrangement of plates. Its latest product, CPU cooler CNPS9900DF, is considered to be universal in terms of compatibility and implemented facilities. Still, some IT experts view this model as a modification of previously launched Zalman CNPS9900 MAX, although with two fans. In spite of visual resemblance, the company tried to design a truly uncommon cooler, with remarkable specifications and reliability.



Framework Peculiarities


Zalman CNPS9900DF is distinguished by an unusual framework. It's not a traditional vertical tower, as long as heatsink ribs feature fan-like location relative to the central axis of symmetry. Such approach provides for a comprehensive heat dissipation over all key motherboard components due to absence of frames on fans. Heat pipes embrace the cooling plates in a circle, then bend at 90 degrees, piercing the base. At first sight it seems that the framework involves six heat pipes, but …
