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 …

New Enterprise-Class SSDs P420m from Micron

Micron Technology, a well-known designer of RAM modules and solid-state drives, finally launches a new enterprise-class series of SSDs. Codenamed P420m, the new-comers are the true followers of P320h drives, but they are ready to offer more than their predecessors. According to Micron, its new entries feature voluminous capacities and ensure high reliability; however, their price range is far more reasonable than other corporate-class products.



SSDs P420m come in two variations: as standard 2.5-inch drives with PCI Express x4 interface or as HHHL (half-height half-length) expansion cards with PCI Express x8 interface. Both species are based on MLC NAND flash-memory, developed under 25 nm technological process. They support a brand XPERT technology (Extended performance and enhanced reliability technology) that ensures genuine reliability and prolonged lifespan. On conditions of daily employment (i.e. wholesome fourfold rewriting operations), the MTBF index makes up five years. … …
