Sharkoon Unveils WPM V2 Power Supplies

Sharkoon Technologies GmbH has expanded its line of PC products with a new series of power supply units, codenamed WPM V2. The series comprises four ATX V2.3 models of 700 W, 600 W, 500 W, and 400 W capacity. All the new-comers are peculiar by a high efficiency level (more than 80%) and a partially modular design. The company promises to release the series into the European market in the short run. Presumably, the retail price will make up 39.99 EUR.



Sharkoon WPM V2 is equipped with all necessary cables to provide sufficient power to the key system components. This list includes one 24-pin connector, one 4+4-pin connector, two 6+2-pin connectors, one floppy connector, six SATA connectors, and five PATA connectors. All PSUs employ a single +12V bus, accompanied by Active PFC. Cooling of internal components is assigned to a low-noise 140 mm fan that efficiently dissipates heat.


One of the most striking peculiarities is reduced power consumption. Herein, in standby mode the …

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.

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 …
