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 …

Evga Debuts with a First-Rate ACX CPU Cooler

Evga, a company primarily known for high-end graphics solutions, decided to expand its production line by entering cooling market. Herein, it elaborated a first-rate CPU cooler, entitled ACX (codename: 100-FS-C201-KR). The new-comer features 164x134.5x91.5 mm dimensions and weighs 1065 g. Luckily, it can be already found in free sale for a price of $50.



The ACX is a tower-like air cooler that is able to efficiently remove heat from all processors that are compatible with the following sockets: Intel LGA 2011/1156/1155/1366/1150/775 and AMD FM1/FM2/AM3/AM3+/AM2/AM2+.


Evga ACX consists of an aluminum heatsink, five copper heatpipes that support Direct Touch technology, and one PWM fan of 120 mm dimensional type. The heatsink is composed of multiple thin plates, which differentiate themselves by an unusual framework. Such framework enables the emergence of two airflows around the heatpipes. According to Evga, this promotes for a better heat removal process.

Intel may release six-core processor Core i7-3970X EE

The top board platform Intel LGA2011 is not yet very demanded among customers, mainly due to the high prices of components — motherboard with chipset X79 and processors Intel Sandy Bridge-E. However, it should be remembered that the models LGA1366 also initially were desirable for only enthusiasts with a tight purse, and only in 2010, with cheaper motherboards and the release of new, more powerful processors, Core i7, (Bloomfield / Westmere) sales statistics of LGA1366 components rose considerably.



It is possible that consumer interest in the LGA2011 platform will also grow this and especially next year. Part of this will contribute to six-core Core i7-3970X Extreme Edition which is expected to be released. Core i7-3970X EE has a clock speed of 3.4 or 3.5 GHz stock, which is in turbo mode increases up to 4.0 GHz. Other features of the model coincide with those of the 3960X:

— Process technology: 32 nm Sandy Bridge-E architecture;

— The number of cores / streams: …
