Graphics Card Sapphire Toxic HD 7970 GHz Edition Review

Up-to-date facilities provided by graphics cards manufacturers allow customers to create various graphic configurations, including the activation of several monitors within a single card. Indeed, contemporary technical approaches transform traditional video adapters into video gurus. The latest development of Sapphire, a flagship model Toxic HD 7970 GHz Edition, offers up to 6 GB of GDDR5 memory and promotes for the activation of six monitors in Eyefinity. Such options exceed those integrated into a reference model, AMD Radeon HD 7970 GHz Edition, and are able to ensure a dramatic increase in performance.

Technical Peculiarities

Sapphire decided to base its flagship model on GPU AMD Tahiti with an integrated delimiter which lowers the clock frequency on the overshoot of thermal threshold. Its standard frequency equals to 1050 MHz, nominal frequency – 1100 MHz; sill, this GPU features Lethal Boost options that increase the frequencies up to 1200 MHz. This graphics card is …

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 …

TP-Link Unleashes a New Router with Built-In Battery

Following the general tendencies in PC market, router segment also takes the direction towards compactness. This is dictated basically by the necessity to move from one place to the other (i.e. during business trip). Compact routers offer similar to standard solutions performance plus convenience while transportation. The line of products designed by TP-Link involves both, typical and compact routers.

Model TL-MR3040 is attributed exactly to compact solutions with one peculiar feature: built-in battery for 2000 mAh. The battery is able to operate up to four hours as access point under 802.11n standard. Router might be powered as from network adapter, so from a laptop via USB cable.

There is a possibility to employ this model as typical router tied to the wired network. The integrated WAN cable serves specifically this means; moreover, it can be joined with ADSL modem or with a local network. In addition, TL-MR3040 might operate as a client for WISP networks.
