Motherboard Asus Z97-Deluxe Review: Getting to Know a New Intel’s Chipset

Intel’s Z-series chipsets have been recently supplemented by a new Z97 Express companion. Its release coincides with the launch of an updated Haswell Refresh CPU line for LGA 1150 socket. The new platform is thought to support PCI Express M.2 interface that substitutes an old-fashioned mSATA one. It is also supposed to support SATA Express interface and the forthcoming Intel Core 5th generation CPUs. What are the real differences between Z97 and preceding chipsets? Let’s find it out through the example of Asus Z97-Deluxe motherboard.

Promising Speed Forecasts for AMD Radeon 8000 Sea Islands

AMD is continuing its work on the new GPU generation codenamed ‘Sea Islands’. The new series is prognosticated to be released in the coming winter. All the products with this GPU will be branded Radeon 8000. AMD manufacturers claim that their new graphic processing units will be 40% more efficient due to the implemented advanced technologies. There is not so much news about the future GPU architecture, although cardinal changes are barely possible.

Sea Islands chips will be equipped with 5.1 billion transistors as compared with the current 4.3 billion items applied in the products. This augmentation will facilitate the increment of efficiency. The chips will be developed according to the already tried-and-proven 28 nm technological requirements. The increase of transistors is not as large due to the adherence to the ascribed norms. It should be underlined that the implementation of the old technologies does not imply the considerable warming up of the chips; the developments …

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 …
