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 …

The Designer Series of BenQ Monitors Has Been Widened by the 27-inch PD2710QC Model

A new model of BenQ monitors under the PD2710QC codename has recently broadened the Designer line. This novelty, with Animation, Darkroom and CAD/CAM special modes preinstalled, is intended for designers and professionals working with graphics and video.



PD2710QC has an IPS 27-inch LCD panel with the 2560 x 1440 pixels resolution. Its brightness factor is 350 cd/m2, contrast ratio – 1000:1, and the response time – 12 ms. The device covers 100 % of sRGB and Rec.709 sets of colours, as well as supports Flicker-free and Low Blue Light technologies.


Among other peculiarities of this BenQ product one can notice embedded speakers of the total 2 W capacity and a convertible stand, which allows to adjust the height in the 130 mm range and to change the landscape display operation mode into the portrait one.


The interface contains an HDMI, a DisplayPort and a USB-C port.

ASRock Outs N3150DC-ITX Mainboard

ASRock has gladdened all devotees of small-sized, power-efficient & sustainable PC/multimedia systems by the introduction of a mini-ITX motherboard, entitled N3150DC-ITX. The model comes equipped with a 4-core Intel Atom N3150 CPU, running at 1.6 GHz basic frequency with the possibility to overclock up to 2.08 GHz frequency. Its key privilege is a sparing TDP level – 6 W only.



ASRock N3150DC-ITX boasts a totally passive cooling: the PCB houses a noiseless heatspreader without a fan. Memory subsystem is represented by two SO-DIMM slots which support the installation of DDR3/DDR3L-1600 MHz modules. The PCB teases only top-tier hardware components, including solid-state capacitors, ELNA audio caps, etc.


Storage might be organized due to a pair of SATA III 6 Gb/sec ports and the same number of SATA II 3 Gb/sec ports. A single PCI-e 2.0 x1 slot is intended for an expansion card, while mini PCI-e Express slot – for a wireless network interface module.
