Philips Boasts the Slimmest 239C4QHWAB PC Monitor

MMD corporation has just introduced its newest PC monitor under Philips brand name. According to the manufacturer, the 239C4QHWAB is the world’s slimmest 23-inch model in the market: its depth does not exceed 12.5 mm. The display is made of 100% recyclable material and is peculiar by the support for Miracast interface. The latter secures immediate, wireless data transfer from the Android-based mobile device to the display.

The model is based on IPS panel with a power-efficient LED backlight. It features rather striking specifications:

— Full HD resolution (1920x1080);

— 20M:1 dynamic contrast, 1000:1 static contrast:

— 178/178 degrees viewing angles;

— 250 cd/m2 brightness;

— 5 ms response time;

— 16:9 aspect ratio.

The 239C4QHWAB is equipped with two stereo speakers (6 W overall power), 3.5 mm output for the headphones, VGA video output, and HDMI port with MHL support; the latter allows for the charge-in of mobile devices, connected via a …

Graphics Card MSI N650 Ti PE 1GD5/OC Review

PC hardware of average price category is traditionally in demand with a wide range of customers. Graphics cards are not exception, especially if the manufacturers offer truly outstanding facilities for comparatively medium price. The launch of GeForce GTX 650 Ti adapter raised an army of graphics solutions based on it; still, each company tries to deviate in some terms from the reference model. Thus, MSI introduced N650 Ti Power Edition 1GD5/OC model which takes GTX 650 Ti adapter as the basis, but employs fundamentally original printed circuit board and cooling system.


Graphics card MSI N650 Ti PE 1GD5/OC features all attributes ascribed to Power Edition series. Printed circuit board has been elongated to 230 mm, as compared to the 154 mm in reference GeForce GTX 650 models. Along with the PCB elongation, MSI implemented a reinforced 5-phase VRM scheme (4+1) that is intended at operational intensification on heightened frequencies. The connection of additional …

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 …
