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 …

LG Introduces Cinema 4K 31MU97 PC Monitor

Graphic designers, photo editors and fans of prime-quality imaging are now pleased by the future release of a new professional PC monitor from LG, codenamed 31MU97. The model belongs to Cinema 4K generation, providing for the best viewing/work experience. It is based on 31-inch IPS panel with 17:9 aspect ratio and features an industry-leading Digital Cinema 4K 4096x2160 pixels resolution. The release date will be announced shortly.

LG 31MU97 boasts 97% color gamut in DCI-P3 environment and up to 99.5% gamut in Adobe RGB environment. In order to cover the most colors, the display employs 10-bit presentation. The integrated IPS panel ensures the widest viewing angles (178 degrees H/V) and the highest dynamic contrast – 1M:1. In addition, a large screen area allows users to include more tools and several windows into the working area.

To continue, this monitor is equipped with a pair of exclusive utilities. The first one, Dual Color Space, enables simultaneous display of two …

Future Technologies are Right Here with Sharp PN-K321H Monitor

IGZO, an advanced technology employing semiconductors on Indium, Gallium, Zinc, and Oxide basis, is gradually penetrating PC monitors industry. It is called to ensure an ultra-high pixel density and, as a result, — an ultra-high sharpness. For sure, being an innovative approach in the development of monitors, end-products currently cost a pretty penny. Sharp is considered to be a pioneer in this endeavor, vigorously implementing IGZO panel in its latest displays.

Hence, Sharp has officially announced the launch of a new 32-inch monitor based on IGZO array and entitled PN-K321H. It features 35 mm case depth, 16:9 aspect ratio, and quite wide viewing angles. According to the manufacturer, the nominal resolution index is estimated as 3840x2160 pixels. The display is housed on a voluminous stand that enables its rotation at 90 degrees to achieve portrait mode arrangement.

Due to the implementation of IGZO panel with high electron mobility, Sharp has managed to attain the …
