The latest graphics findings made it possible to use a mainstream video card in 4K Ultra HD environment. LG has announced a 23.8-inch monitor with 4K resolution (3840x2160) that can be integrated within a standard PC system. The model features 16:9 aspect ratio & boasts the widest viewing angles – 178 degrees in both aspects. Nonetheless, its price makes up $349.99 only.



LG 24UD58-B is developed on IPS panel with 5 ms response time. It ensures the most efficient viewing conditions: 250 cd/m2 top brightness and outstanding contrast index. The support for AMD FreeSync technology allows for automatic adjustment of refresh rate in order to guarantee premium viewing level. The model typically consumes 23 W power.


The I/O panel accommodates a single DisplayPort 1.2 and two HDMI 2.0 ports. Besides, it’s possible to detach the display from the stand and apply it to the wall, thanks to 100x100 VESA bracket.


LG’s new monitor boasts a range of advanced elaborations. …

The Swiftech company presented a new revolutionary water unit of the Apogee SKF series. It’s called Apogee SKF-TR4 and is designed for AMD Ryzen Threadripper processors.



The specialty features an innovative cooling engine (its surface area is enlarged by 30%) and customisation adjustments that are able to satisfy all users’ needs. This water unit is produced out of copper. In the place of base-processor contact the water block’s inner surface is covered with pinholes, extending the heat exchange space. Besides, in-and-out openings are located in front of active crystals in the multichip Threadripper module.


The waterblock mountings fit only system boards with the TR4 (SP3r2) CPU connectors. The novelty supports the Addressable RGB Iris tech and is provided with the Swiftech Iris-Eco controller. Two strips of RGB LEDs allow Apogee SKF comply with any colour scheme.


Apogee SKF-TR4 will hit the market at the end of October 2017. It will cost approximately $108.

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 …
