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.

Monitor Asus PA248Q Review

The market of displays is full of models with the 16:9 height-to-width aspect ratio, what can't be said about 16:10 models which go in quite scant supply. Still, the latter are of great demand among computer enthusiasts. The inventory of monitors produced by Asus includes models of various height-to-width aspect ratio. Currently, the company is introducing exactly 16:10 product, codenamed PA248Q. The chief peculiarity of Asus PA248Q is seen in the availability of USB 3.0 hub that offers advanced facilities for customers.



Design


Design of monitor Asus PA248Q greatly resembles that of its predecessor, PA246Q. The frontal panel contains a red stripe and vertical control buttons. The display is dull and void of loud dirtying. The swivel gear allows the customer to rotate the display 92 degrees clockwise. The stand contains measurement marks with digits that show the degree to which it's possible to raise or rotate the monitor. Vertical control buttons are located on the right …
