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 …

Meeting Soon: Two New Chassis of Luxo Series from Gigabyte

Gigabyte, a globally-celebrated PC hardware manufacturer, is going to launch two new PC chassis, embraced in Luxo series. The novels, designed in mid-tower form-factor, have been entitled as Luxo M20 and Luxo M30. Both models are housed in reliable steel cases (SECC) but have got some plastic insertions. Their dimensions are outlined as 440x192x430 mm. No information about the pricing or exact release date has been promulgated so far.



New chassis from Gigabyte are equipped with four pre-installed fans of 120 mm dimensional type. In addition, it’s possible to incorporate one more fan to enforce the existing cooling system. Traditionally, the products are available also for the installation of a liquid-cooling system; for this Gigabyte has drilled a couple of holes on the rear facet for the connection of water-cooling tubes.



Luxo M20 will be delivered in red-and-black color variation, while its companion Luxo M30 – in blue-and-black coloring. Both models are thought to …

Xigmatek to Launch Alfar Chassis This Month

Xigmatek is on the verge of launching its new series of chassis, codenamed Alfar. The series consists of three models which differentiate from each other by the color of insertions on the frontal grid (black, white and orange). The casing itself is made of steel and painted totally black. All three enclosures are designed in mid-tower form factor and are ready to accept motherboards of mini-ITX, micro-ATX and ATX dimensions.



Xigmatek Alfar houses seven PCI expansion slots, can accept CPU coolers of up to 160 mm in height, graphics cards of up to 320 mm in length, and a standard power supply unit. The chassis are furnished with three external 5.25-inch drive bays, four internal 2.5-inch bays, and analogous number of bays for 3.5-inch drives. Interface panel is located on the top board and accommodates a couple of USB 3.0 ports and standard 3.5 mm audio sockets.


The nominal delivery set of Xigmatek Alfar contains two 120 mm fans, located on the frontal and rear boards; …
