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 …

Iiyama Launches X4070UHS Monitor with an Unusual Base

Iiyama Corp. is not used to sit idly, delivering ever newer visual solutions. This time the company launches a 39.5-inch PC monitor with a nontrivial stand. The ProLite X4070UHS model rests on two demountable racks, instead of a single central column. Nevertheless, the display supports well-loved facilities, such as Picture-in-Picture mode and POP (split of the screen into four windows). It features a pure black case and a high gloss screen coating.



Iiyama X4070UHS is based on MVA panel with LED backlight. It is thought to support Ultra HD/4K resolution (3840x2160 pixels) as well as 5000:1 static contrast. Besides, the model ensures 350 cd/m2 brightness, the display of 16.7 million colors, the widest possible viewing angles (178/178 degrees in both aspects), and ultrafast response time – 4 ms (GtG environment).


The monitor is equipped with two speakers (6 W power in total), a pair of audio in/outputs, RS-232 socket, as well as a set of video ports: DVI-D, HDMI, …
