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 …

ASRock Launches a New Motherboard with Intel SBA Support

ASRock announces the launch of a new budget-priced motherboard B75M-DGS R2.0. The model does not differentiate itself by an attractive design or wide overclocking facilities, as far as its main predestination is a stable operation in large corporate networks. The board is known to support Intel Small Business Advantage (SBA) software applet that optimizes PC operation and increases its performance. Despite such promising commodities, its price doesn't go over $60 per unit.



ASRock B75M-DGS R2.0 is designed in micro-ATX form-factor; this limits the number of supported expansion slots and other interfaces. As seen from the codename, the motherboard is based on Intel B75 system logics and shows compatibility with Intel Celeron, Intel Pentium and Intel Core i3/i5/i7 processors (second and third generation) compatible with Socket LGA1155. Memory subsystem consists of two DIMM slots which support two-channel DDR3-2200 MHz modules, the overall capacity of which might achieve 16GB …

HP Employs Processors AMD Athlon II X2 221 and Sempron X2 198

The release of hybrid AMD processors of A series was announced about a year ago, however, their actual appearance in the market was delayed for a few months. It is a well-known fact that a part of those processors for Socket FM1 platform has got idle graphics block; this part of processors has been codenamed Athlon and Sempron. The two processor models from this series Athlon II X2 221 and Sempron X2 198 can be currently found in PCs manufactured by HP company.



Both processors have been observed in the list of specifications of desktop PCs delivered by HP: Athlon II X2 221 is employed in HP Pavillon p6-1169cx and p6-1226cn models, while Sempron X2 198 is employed in HP Pavillion p6-1152cx, 1230cx, 1231cx, and 1159cx models. The major peculiarity of such technological solution is that HP PCs with those processors are delivered only to the Chinese market.


Two-core Athlon II X2 221 operates at 2.8 GHz frequency, and accommodates 1 MB cache memory of the second level. It is …
