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 …

Processors Intel Haswell to Rival Accelerator NVIDIA Tesla

Intel Corporation has the intentions to introduce DDR4 memory into their server processors of Haswell series. The launch of such technological approach is planned for the 2014, however the developments in this sphere have already started. Intel’s server solutions will become a part of Grantley platform and the samples of their new series will allegedly be announced next autumn. The preview of new processors makes it clear that some of the chips will be distinguished by the increased heat generation performance which will reach 160 W.



Hence, 16-core processors Haswell-EP will rival parallel computing accelerator NVIDIA Tesla but not AMD server solutions. Intel is going to provide various working frequency options and options with different number of active cores. At the same time, TDP will fluctuate within ranges of 160, 145, 135, and 120 W. In its turn, accelerator NVIDIA Tesla, which is based on GK110 processor, consumes approximately 300 W.

DAS Promise Pegasus R4 Review

Data storage units have become an integral part of PC hardware in recent years. Such conjuncture is simply explained by the rising necessity to store huge amounts of information and transfer the data to various devices. NAS and DAS units have been developed with the intention to solve all storage problems, however, the efficiency of their work is much dependent on the interfaces they use for data transfer. USB 2.0 interfaces are unable to cope with voluminous info; the prevalent now USB 3.0 and eSATA interfaces are efficient only for a single winchester. But when it comes to the management of really huge data blocks, there appears a need for a more advanced solution. Promise Technology dares to solve all vital issues by releasing DAS Pegasus R4 with Thunderbolt interface which is notable for the high and stable data transfer speed with the retention of compatibility.
