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 …

MSI Z97 Overclocking Motherboards are Ready for High Scores

MSI has replenished the lines of companies with a few series of motherboards based on a fresh Intel Z97 chipset. MSI Z97 Overclocking series is a peculiar one, ready to marvel by high scores. It is introduced by three hi-end models: MSI Z97 MPower, MSI Z97 XPower AC and MSI Z97 MPower MAX AC. In keeping with the idea, the triple offers high functionality, combined with an unprecedented stability and a striking design.



Being the basis for an overclocking system, these motherboards ensure a long-lasting durability in extreme loading conditions, primarily due to the premium hardware base. Hence, the models are equipped with Military Class 4 components with Guard-Pro core, which provides for the highest protection against high temperatures, humidity, electromagnetic distortions, and electrostatic discharge. Besides, Guard-Pro features MSI ECO Power technology that disables power on idle controllers for a more power-efficient operation.


To continue, it should be noted that all …

Features of Models AMD Athlon II X4 (FM2)

Like Intel, AMD Company is not protected to the release of a large number of faulty processors, which are eliminated at the stage of laboratory tests. Some have a non-working cache (or part thereof), other — x86-cores, and others — a graphics block, and a fourth — a weak memory controller. According to this, there are releases of less productive CPU, but working with a moderate price tag. About unlocking cores / cache in AMD processors users probably know firsthand.



As the saturation of the defective inventory APU Trinity platform FM2, AMD will decide on the mass production of new models of AMD Athlon II X4. They will be easily distinguished from its predecessors on the number of the form 7xx.


Integrated Graphics Radeon VLIW4, of course, will be disabled. Frequency will be slightly reduced for marketing purposes. Overclocker devotees will primarily be interested in quad-core Athlon II X4 750K of free factor. The operating frequency of the model — 3.4 GHz, cache …
