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 …

I-O Data Introduces New SSDN-3V to the Home Market

I-O Data, a well-known Japanese developer of top-tier peripheral and interface products, is going to introduce its new SSD series, codenamed SSDN-3V. The newbies will become available in the home market already at the end of the current month. The series involves three models of 60 GB (SSDN-3V60), 120 GB(SSDN-3V120), and 240 GB (SSDN-3V240) capacities. All the models are thought to support SATA 6 Gb/sec interface.



Solid-state drives from I-O Data are based on SandForce/LSI SF-2281 controller and employ NAND flash-memory, designed under 24 nm technological process. SSDs feature 7 mm case depth, but the availability of a dedicated adapter promotes for their installation into a standard 9.5 mm drive bay.


In regard to performance, SSDN-V3 drives offer up to 306 MB/sec speed on consecutive reading operations and up to 186 MB/sec on consecutive writing operations.


Moreover, the manufacturer will deliver the products in a package with a special adapter for the connection …

Low-Profile Cooler Noctua NH-L12 Review

Noctua, an Austrian developer and supplier of high-end cooling systems, is well-known for the design of versatile products which are able to satisfy the needs of any consumer, starting from average home users and finishing with devotees of overclocking. The recent Noctua creation is the low-profile CPU cooler destined to be employed in HTPC systems and other compact chassis. This cooler is characterized by the horizontal localization of radiator that allows its installation into a quite narrow casing. At the same time, the model is efficient enough to manage high-performance advanced processors.



Design and Framework


Noctua NH-L12 is notable for the classic design and framework. It features 150x128x93 mm dimensions (with two fans) which barely speak of low-profile form factor. NH-L12 is compatible with different CPU sockets, including Socket AM2, AM2+, AM3, AM3+, LGA 2011/1366/1156/1156/775. This cooler consists of horizontal radiator, four copper heat pipes which pierce …
