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 …

Asus Showcases GTX 960 DC2 Videocard

Asus has complemented its Black Edition series of videocards with another model – the GeForce GTX 960 DC2 (codename: GTX960-DC2-4GD5-Black). Its major peculiarity is the employment of 4 GB GDDR5 memory that is sure to improve gaming efficiency in multi-display high-resolution environment. The model supports all modern standards (DirectX 12, OpenGL 4.4) as well as proper Nvidia’s technologies: SLI, G-Sync, GameWorks, GPU Boost 2.0, ShadowPlay, GameStream.



Asus GeForce GTX 960 DC2 is based on Nvidia GM206-300 GPU (1024 CUDA, 64 TMUs, 32 ROPs). It operates at 1126 MHz frequency with overclocking possibility of 1178 MHz. The integrated 128-bit memory operates at 7010 MHz efficient frequency.


This graphics card entails Super Alloy Power components and an optimized DirectCU II cooling system. The latter ensures that heatpipes touched CPU surface for an unprecedented heat dissipation. The cooler comes with a pair of fans, one of which features CoolTech hybrid design. The …

KFA2 Launches Two Graphic Cards Simultaneously

KFA2 has announced the release of two new graphic cards which boast the indisputable performance and efficiency. Codenamed Geforce GTX 660 Ti EX OC 2GB and Geforce GTX 660 Ti EX OC 3GB, this couple supports all technologies ascribed to GTX 600 graphic adapters, including PhysX, 3D Vision, GPU Boost, Adaptive Vsync. In addition, they enable the creation of various configurations with three monitors for game-based purposes (and an additional fourth monitor for non-gaming purposes).



Both models are equipped with DisplayPort, DVI, VGA, and HDMI interfaces to provide for the multi-functional facilities. KFA2 Geforce GTX 660 Ti EX OC 2GB model accommodates an advanced cooler with two fans and four nickel-plated heatpipes based on aluminum platform. It has got 1344 CUDA cores and employs GDDR5 memory interface; the overall memory volume capacity equals to 2 GB, while its speed approximates 6 Gb/sec.
