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 …

Arctic Cooling Intros Two Modifications of Freezer CPU Cooler

Arctic Cooling AG, a well-known Swiss developer of cooling solutions, has recently introduced its newest CPU cooler, Freezer, in two modifications: i11 and A11. Both versions have got tower-like framework, featuring 108x90x130 mm dimensions. The Freezer i11 is compatible with Intel LGA 2011/1156/1155/1150 socket platforms, whereas its companion is intended for AMD Socket FM1, FM2, AM3, AM3+, AM2, and AM2+. To say more, this pair is able to cool down the ‘blaze’ of CPUs with 150 W TDP.



Arctic Freezer i11/A11 consists of an aluminum heatspreader with forty-five plates, three U-shape copper heatpipes, and one 92 mm fan. The heatpipes are thought to support direct contact technology that dramatically improves heat transfer process.


The implemented fan is developed on a fluid dynamic bearing and is equipped with a PWM controller. The latter assures that the blades could change their rotational speed within the ranges from 500 RPM to 2000 RPM. Herein, the maximal airflow …

Elsa to Replenish the Line of Graphics Cards with GeForce GTX 670

Elsa Technology has announced the future release of its alternative version of graphics adapter Nvidia GeForce GTX 670. The new model is developed according to 28 nm technological process and employs GK104 chip with 1344 CUDA cores. It also boasts the implementation of advanced architecture, called Kepler. The major distinction of Elsa GeForce GTX 670 from its reference models is the integration of Silent Air Cooling technology (SAC).



This model is based on blue circuit board destined for PCI Express 3.0 x16 bus. Elsa graphics card is equipped with GDDR5 memory type (256 bit interface) and has got 2048 Mb of overall volume capacity. The backplate is assigned for a couple of DVI ports, a single HDMI, and one DisplayPort 1.2 port. This graphics adapter is compatible with DirectX 11 and employs Nvidia FXAA and Nvidia TXAA technologies for the improvement of imaging. It also supports Adaptive Vsync mode for more smooth games playback, as well as, Nvidia SLI, Nvidia 3D Vision, Nvidia …
