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 …

KFA2 Introduces Shortcut GTX 960 OC 2 GB Video Card

KFA2 comes out to the European market with a shortcut version of Nvidia’s GeForce GTX 960 adapter. The GTX 960 OC 2GB features 193x124.3x41.5 mm dimensions, compatible with small-sized PC cases (mini-ITX form-factor). Despite an unusual design, the model offers five video outputs: three DisplayPort, one DVI-I and one HDMI 2.0. The new-comer will be available from retailers at 199 EUR price tag.



KFA2 GTX 960 OC 2GB is based on GM206 GPU with 1280 stream processors, 10 SMM, and 64 ROPs. It operates at heightened clock frequencies – 1165 MHz (nominal) and 1228 MHz (dynamic). The core is supported by 2 GB of GDDR5 memory (128-bit bus) that runs at the reference 7010 MHz clock frequency. Power supply is organized by means of a 6-pin connector.


As for cooling system, it is represented by three copper heatpipes and a pair of low-noise fans. It should be noted that in standby mode the cooler totally switches off the fans in order to minimize the noise level.
