Meet New Frameless U2717D Monitor from Dell

Taking into account an ascending popularity of WQHD displays, Dell decided to expand its portfolio by a new high-resolution monitor – the UltraSharp U2717D. The model is based on 27-inch IPS panel with the top brightness index (350 cd/m2). It is also notable for the widest viewing angles (178/178 degrees) and a relatively fast response time (6 ms). Pricing has not been announced yet.

Dell UltraSharp U2717D features 2560x1440 resolution, 16:9 aspect ratio and 1000:1 contrast index. It promises the coverage of 99% RGB environment as well as the highest color rendering (DeltaE <2).

The other attraction of the monitor is nearly frameless design: the display is edged by an ultra-thin frame, replenished by a multifunction stand. The latter promotes for the adjustment of height, angle of slope, and aspect positioning (swivel & pivot). The display boasts a rich assembly of external interfaces; thus, it offers a pair of HDMI 1.4 ports with support for MHL 2.0 options, a pair …

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 …

Deepcool Releases CPU Cooler Gammaxx 400

The assortment of products designed by Deepcool Industries company has been replenished with a high-end processor cooler Gammaxx 400. The new arrival is differentiated by an outstanding efficiency and minimal noise level. Cooler’s dimensions (which equal to 135x76x159 mm) facilitate its installation into any standard casing of ATX form-factor.

Gammaxx 400 is equipped with four sintered U-shaped heat pipes that have direct contact with the processor surface. This promotes for the improved cooling activity. The solid aluminum radiator accommodates fifty edges to ensure the appropriate heat dissipation. The radiator comprises 120 mm fan with a hydrodynamic bearing and four blue LEDs. The average rotation speed achieves the index of 900-1500 r/min, while the noise level does not exceed the margin of 32.1 dB.

Cooler Deepcool Gammaxx 400 is activated by means of 4-contact socket which provides for the revolution monitoring and noise level reduction via PWM option. This model is …
