Monitor Dell U2713HM Review

Monitors with high resolution have deeply penetrated into our lives. Full HD resolution is considered to be a necessity for the up-to-date video standard, so manufacturers of not only PC monitors but also other devices, such as smart phones, mobile gadgets, etc., try to implement this standard into their products. 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. It is fixed on a durable plastic stand connected to a black base with beveled angles and a central turntable. The base is made of solid metal; its rear board accommodates six rubber feet which are firmly pressed to the surface and save the monitor …

Water 3.0: a New Series of Liquid Coolers from Thermaltake

Thermaltake, a viable designer of versatile PC hardware components, has recently unveiled its new series of liquid cooling systems. Entitled simply Water 3.0, the products constitute themselves as all-in-one cooling solutions with high efficiency and low noise level. The series is introduced by three models, — Water 3.0 Performer, Water 3.0 Extreme and Water 3.0 Pro, — targeting different customer groups.



All liquid coolers included into the lineup consist of a pump integrated into a waterblock, a copper base, a couple of 120 mm fans, and leak-proof pipes which protect the liquid from leakages or evaporation. Heatsink design is individual for each of the models. One should mention that Thermaltake delivers its liquid coolers with dedicated Windows-compatible software for the monitoring and adjustment of all key parameters, including fan rotational speed, liquid thermal conditions, and pump efficiency.


The first model, Water 3.0 Performer, features 120 mm heatsink of a …

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 …
