HIS Starts Selling Radeon HD 7970 GHz Edition in US Market

Hightech Information System presents its own version of AMD's Radeon HD 7970 GHz Edition graphics card to the US hardware market. Codenamed Radeon HD 7970 IceQ X2 GHz Edition, this card is characterized by the integration of the most up-dated technologies and high-end components. The model is based on Tahiti XT chip developed under Graphics Core Next architecture template (28 nm technological process).

HIS Radeon HD 7970 IceQ X2 GHz Edition takes blue printed circuit board designed for PCI Express 3.0 x16 bus as the basis. It is distinguished by the implementation of the reinforced power subsystem and by the compatibility with DirectX 11.1 technology. The employed GPU houses 2048 current processors. It operates at 1000 MHz frequency in nominal mode but can be accelerated to 1050 MHz during overclocking activity.

This graphics card accommodates 3GB of GDDR5 video memory which features 384-bit interface. Its frequency formula demonstrates up to 6000 MHz on standard …

Unusual PC Monitor HP Envy 27 Review

High-end PC monitors segment is abundant in models of different frameworks, designs and facilities. Nevertheless, the majority of manufacturers offer rather alike solutions, leaving demanding consumers dissatisfied. HP is the company known for challenging the rising demands, so the introduction of HP Envy 27 was an ‘expected surprise’ for all interested parties. This monitor distinguishes itself by an unusual design, remarkable specifications, and traditionally high price. It’s time to vindicate those privileges de visu.

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 …
