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 New PB238TR Monitor with Unprecedented Specs

Asus has recently showcased one more high-end PC monitor – the PB238TR. It features 23 inch display and boasts 549x323.7x244.5 mm dimensions (with stand). The model is peculiar by the support of Human Sensor technology. The latter keeps track of the user’s presence; on his absence for a predetermined time period, the monitor turns to a standby mode. This promotes for a well-judged power consumption, resulting in a dramatic cost efficiency.

Asus PB238TR is based on IPS array with 6 ms response time and Full HD resolution (1920x1080). IPS ensures also a perfect color rendering, wide viewing angles (178/178 degrees in both aspects), 250 cd/m2 maximal brightness, as well as a striking dynamic contrast of 50M:1. The model is furnished with onboard speakers (2W each) and two video ports: D-Sub and DVI-D. Connectivity with external peripherals is realized by means of two USB 2.0 ports.

Gelid SlimHero Gains an Off-the-Shelf Product Status

First seen at CeBIT exhibition, CPU cooler SlimHero from Gelid has turned into an off-the-shelf product. The new-comer joined Gelid Silent cooler series and is already available for customers at the price of around $32. The major distinctive peculiarity applied to the cooler is its framework: it features only 59 mm height that is quite appropriate for the installation into small-sized mini-ITX/mini-Tower PC cases or into advanced HTPC systems.

At the same time, SlimHero is equipped with four copper heat pipes, a range of aluminum ribs, and 120 mm fan. The employment of copper in the design of heat pipes is to significantly increase heat transfer to the ribs. Moreover, their original shape ensures low resistance to airflow, resulting in a more efficient cooling process.

Gelid SlimHero demonstrates wide compatibility with a lump of present-day desktop platforms: AMD Socket FM1, FM2, AM2, AM2+, AM3, AM3+, as well as Intel LGA 775, 1150, 1155, 1156, 1366. According to Gelid …
