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 Launches ‘Art-Oriented’ PA238Q Monitor

ProArt series of PC monitors from Asus has been recently refilled with a new 23-inch model, codenamed PA238Q. The product is targeting professional art designers that specialize in graphics and video editing. Along with unprecedented visual specifications, the new-comer is distinguished by optimized power efficiency. Hence, on maximal loading it consumes up to 33 W power, whereas on idle/sleep mode – not more than 1 W. This art-oriented innovation is already available in the European market at 248 EUR.



Asus ProArt PA238Q is based on AH-IPS panel equipped with LED backlight. It promotes for an ideal color rendering with Full HD resolution format. The integration of a path-breaking matrix ensures the widest viewing angles of 178/178 degrees in both aspects, 250 cd/m2 brightness, 6 ms response time (GtG environment), 16.7 million of displayed colors, as well as 50.000:1 dynamic contrast.


It should be underlined that this monitor comes with a high-precision factory …
