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 …

MSI Introduces Radeon R9 270X Gaming 2G ITX Graphics Card

All devotees of mini-ITX PC systems now can enjoy the privileges of innovative graphics solutions with a remarkable Radeon R9 270X Gaming 2G ITX adapter. The new-comer features 170x120x35 mm dimensions only and fits any modern small-sized chassis. It is based on AMD Curacao XT GPU that boasts 1280 stream processors and offers nominal, as well as overclocked operational frequencies. The card supports the latest DirectX 11.2 and OpenGL 4.3 standards, in addition to the bunch of AMD’s proprietary technologies (i.e. Eyefinity, Mantle, PowerTune, Stream, CrossFireX, PowerPlay, HD3D, etc.).



MSI Radeon R9 270X Gaming 2G ITX is able to demonstrate three different operational modes: Silent, Gaming, OC. The nominal clock frequency in all modes makes up 1030 MHz, however during overclocking this index rises up to 1050 MHz – Silent mode, 1070 MHz – Gaming mode, and 1080 MHz – OC mode. The GPU is accompanied by 2 GB of GDDR5 memory (256-bit interface); it runs at 1400 MHz/5600 MHz …

Biostar Outs a Triple of Racing Motherboards

Biostar has begun the 2016 year’s history with the launch of a new series of motherboards, entitled Racing. Currently, the lineup includes three ATX models — Z170GT7, H170GT3 & B150GT5 — based on Intel Z170, H170 and B150 chipsets respectively. The triple is compatible with Intel Skylake processors for Socket LGA1151.



Biostar Racing motherboards are developed according to Super 5 Design template. It entails a number of advantages. Among them:

— Super Sound – the employment of a high-quality audio subsystem Biostar Hi-Fi audio;

— Super Face – a unique visual styling of the PCB;

— Super Easy – the implementation of a well-considered hardware layout;

— Super Power – the usage of a reliable power subsystem with super durable ferrite and solid-state capacitors;

— Super Fun – the introduction of additional components for more sophistication (i.e. LED backlight).


Biostar Z170GT7 comes with 4 DIMM slots targeting DDR4-3200 MHz memory …
