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 a New Series of PC Monoblock Units

LG Electronics established the reputation as the global manufacturer of consumer electronics long time ago, but it still amazes the community with ever newer products and approaches. Thus, lately the company has 'shared' the news about the forthcoming delivery of its monoblock units which belong to V720 series. The first two models to appear in the open sale will be V720-D.AE50K and V720-U.AE30K. The basic distinction of both units will be their ultra-thin casings and the integration of all chief system elements at the stand base.



The two models are promised to have as similar specifications, so different features to comply with various needs. Both are furnished with Bluetooth 4.0 modules, TV-tuner, Wi-Fi 802.11b/g/b, card reader. There are USB 3.0 sockets, HDMI socket, and loudspeakers of 7W efficiency. Some other major specifications are listed below.
