Still, progress marvels us with a new development: more advanced WQHD resolution of 2560x1440 is gradually integrated into the monitors. Dell decided not to lag behind the pioneers in this sphere and designed a new model U2712HM.

Design and Ergonomics

Monitor Dell U2713HM is housed in a black or silver-black dull casing. The implementation of WLED lighting allowed the manufacturer to reduce the depth of the enclosure.

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 …
