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 …

Enermax Outs High-Flown Twister Pressure Fan

One of the major requirements for an efficient CPU cooler is a high static pressure. The higher this index is, the more productive the blades are. Quite the contrary, the main requirement for a system fan is a volume of produced airflow, since it affects the air circulation within the case. Taking into account those facts, Enermax decided to elaborate a fan that would unite both demands. That is how Twister Pressure fan came into the market.



Enermax Twister Pressure is a high-efficiency fan targeting to be implementing within CPU cooling solutions. It is based on Twister Bearing 2, which framework has been optimized for a reliable operation under unfavorable thermal conditions (up to 85 degrees) and under high dust content. The second version of Twister Bearing is supposed to run over 160.000 hours in fail-proof mode; this is 60% more than the initial version could perform.


To continue, this fan offers three operational modes: Performance, Silent and Ultra Silent. All of …

Kingston Showcases New SSDNow KC300 Series

Kingston Digital, an established developer and supplier of highly efficient storage solutions, has officially introduced its new line of solid-state drives that entered SSDNow series. Entitled KC300, this line is targeted at a vast audience, starting from corporate clients and finishing with average customers. KC300 includes five models of 60 GB, 120 GB, 180 GB, 240 GB, and 480 GB capacities. According to Kingston, the new entries are supposed to substitute the two preceding SSD lines: Kingston KC100 and Kingston V+200.



SSDs KC300 are designed in 2.5-inch form-factor and feature SATA III 6 Gb/sec interface. LSI SandForce SF-2281 controller is the heart of each drive model. All items included in the series support DuraClass, DuraWrite, S.M.A.R.T. and RAISE technologies that substantially enhance their efficiency. The same way, all the drives are able to complete an automatic data encoding by means of two integrated encoding engines, which work with AES-128 and AES-256 algorithms. …
