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 …

Meet New PSU Tesla R2 from Fractal Design

Fractal Design is the company that distinguishes from its competitors by the incessant dedication towards each product's design and performance. Its recent power supply units lineup, Tesla R2, can be called a benchmark of style and refinement. Of course, the company did not forget about the PSU performance, implementing only the innovative technologies in its development. Tesla R2 series framework and configuration will initially serve the needs of high-end and high-demanding gaming PCs and workstations.

Tesla R2 series has got 80Plus certificate which implies that the product is highly efficient and can compete for the market winning. At the same time, it is characterized by low power consumption which is achieved due to the implemented technologies on heat production decrease. Tesla R2 is equipped with 135 mm fan based on Long Life bearing. It is distinguished by the low-speed rotation and, as a consequence, decreased noise level.

To continue, this PSU is compatible …

Greeting Top-Notch Exoc Sniper Videocard from KFA2

KFA2 ventured upon introducing another cutting-edge videocard developed on Nvidia GTX 970 adapter. The GeForce GTX 970 Black Exoc Sniper features 271x124 mm and takes GM204-200 GPU (Maxwell) as the basis. Similar to the etalon model, the new-comer accommodates 4 GB of GDDR5 memory (256-bit interface), running at 7010 MHz frequency and offering 224 Gb/sec bandwidth index.

As distinct from the Nvidia’s elaboration, KFA GeForce GTX 970 Black Exoc Sniper boasts the integration of the factory-overclocked GPU. It operates at 1178/1329 MHz frequency (base/efficient), surpassing etalon 1051/1178 MHz showings. In order to cope with high power consumption and heat output, KFA2 has imbedded high-quality 5+2-phase power subsystem.

To continue, the model is ventilated by a two-slot Silence Extreme cooler. It consists of four nickel-plated copper heatpipes, aluminum heatsink, a rear backplate as well as a couple of 90-mm fans. On low loading, the system disables one of the fans to …
