Biostar Launches High-Performance Motherboards TZ77B

Biostar has recently introduced its new series of motherboards, codenamed Biostar TZ77B, and is currently starting mass delivery of them to the market. TZ77B model is developed on Intel Z77 logics kit and goes in ATX form-factor. Manufacturers claim that the new series is able to ensure high performance and stability of operation at moderate price. These motherboards support all LGA1155 processors Intel Core (i3, i5 and i7) of the 2nd and 3rd generation.

Powerful graphics core DirectX 11, integrated into Intel Core processors (of the third generation), enables the compatibility with the majority of up-dated 3D games and HDMI 3D Visual technology. Video output is realized via digital HDMI, VGA (analogue), and DVI (with HDCP technology) interfaces. The availability of PCI-E 3.0 x16, PCI-E x16 2.0 (x4) and PCI-E x1 2.0 interfaces adds facilities for digital graphics.

Biostar TZ77B proves to demonstrate up to 95W TDP level, including unblocked CPU with K index. The motherboard …

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 …

Gigabyte Outs a Pair of GT 710 Graphics Cards

Gigabyte has just announced the release of two entry-level graphics cards (with 1 GB or 2 GB DDR3) based on Nvidia’s GeForce GT 710 adapter. The company’s elaboration boasts the implementation of Ultra Durable 2 design that combines top-quality hardware base, reliability and high performance. The card comprises an improved PCB with the best-in-class solid-state capacitors, transistors as well as ferrite chokes.

Despite low-profile orientation, Gigabyte GeForce GT 710 employs active cooling system. The latter consists of a small-sized heatsink and a fan. In terms of efficiency, the company decided to preserve etalon showings; hence, the GPU (GK208, Kepler architecture, 192 CUDA cores) operates at 954 MHz frequency. Yet, the models come equipped with an overclocked memory: 900 MHz/1800 MHz (base/dynamic) frequency.

The kit of external interfaces includes three video ports: D-Sub, DVI-D & HDMI. Moreover, the nominal delivery set contains OC Guru II software package. It …
