Modular Power Supply 650W Chieftec A80

Evaluating the effectiveness of modern computer power supplies, the most attention is paid to their coefficient of performance (COP) at a given load — usually means of 20%, 50% and 100%. At the same time, not less important requirement, established by standard 80PLUS should be considered. That means — the preservation of this level of performance for all occurring in the world supply voltage variations, that is in the range of 100-240 V.



The standard rules of 80PLUS at different levels (Basic, Bronze, Silver, Gold, Platinum, etc.) are performed for two voltage 115 V and 230 V. In both cases, the normalized PS should show the efficiency of not less than specified for each category level. Not usual power supply CTG-650C model of the new A-80 series from the Chieftec company is interesting in that it has officially claimed efficiency of 85% or more, but only for nets 220-240 V.


As the advantages of such solution can immediately be noted a lower price, due to less stringent …

HIS Showcases New Graphics Card with Improved UVD GPU

The line of graphics cards manufactured by HIS has been recently replenished by an alternative Radeon HD 7950 IceQ Boost Clock model. The card takes a modified graphics adapter from AMD and is based on Tahiti PRO chip, developed according to 28 nm technological process. This chip houses 1792 current processors which are designed under an advanced Graphics Core Next architecture.



One of the major technological peculiarities pertained to a new model is the implementation of a unique two-slot IceQ cooler that involves an aluminum heatsink, four copper heat pipes and low-noise powerful fan. As claimed by the manufacturer, the integrated cooling system exceeds the cooler applied in the reference model in terms of heat dissipation power and noise. Hence, noise level produced by IceQ does not exceed the boundary of 28 dB; at the same time, it reduces the GPU temperature at 12 degrees as compared with the reference model.


To continue, Radeon HD 7950 IceQ Boost Clock is based on a …

Meeting the Newest Memory Modules HyperX Beast from Kingston

Kingston continues its developments in the field of PC memory, replenishing its HyperX series with Beast memory modules. Codenamed Kingston HyperX Beast, these models are able to ensure super high-speed operation to provide for unmatched possibilities for overclockers and gamers. The modules feature bright, a bit aggressive fin design and are supplied in the most voluminous capacities (from 8GB to 64GB). Kingston developers are sure that their new products will create the most appropriate environment for advanced users in search for high-efficient, high-capacity memory for their PC systems.



HyperX Beast modules are known to support Intel XMP profile which is employed for unimpeded performance optimization due to the selection of pre-installed profiles. It should be noted that new products are introduced within Predator series that involves the most up-dated memory facilities intended at demanding customers.


'Beast' memory sets operate at up to 2400 MHz nominal frequency …
