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 …

PC Cases Enermax iVektor to Be Launched in Late August

Enermax is going to release its new iVektor series of PC cases already in late August. First seen at Computex 2013, these products draw prime attention due to unusual design and voluminous internal layout. The series counts three models that are differentiated by color: white version – Enermax iVektor (ECA3310A-W), black version – Enermax iVektor (ECA3310A-B), and red version – Enermax iVektor (ECA3310B-R). They are destined to be employed as the basis for the assembling of various system configurations.



All iVektor representatives are developed in midi-tower form-factor, featuring steel and plastic chassis. The cases support ATX/micro-ATX motherboards and seven expansion slots. Internal layout presupposes the incorporation of three 5.25-inch optical drives, as well as seven 3.5-inch drives. The height of a supported power supply unit might not exceed 179 mm.


When the user fills all seven bays for 3.5-inch drives, the maximal admissible length of graphics adapters …

New details about the video card Colorful iGame GTX 680

In June, at Computex 2012 exhibition Chinese manufacturer of Colorful graphics cards announced its plans to release GeForce GTX 680 model with a passive cooling system. These «monsters», of course, require careful laboratory testing, so retail sales of iGame GTX 680 will not be performed at least until upcoming autumn.


Meanwhile, the upcoming release collects more and more of new details. According to the manufacture, graphic card is equipped with a reinforced VRM and dual memory — 4 GB of GDDR5. The power connectors PCI-E Power 8-pin made are located on the back of the PCB.



There are only three video outputs, as opposed to the reference, but all of full-size — DVI-I, HDMI and DisplayPort. The exact code name of the model looks like following «GK104HA-D32». Information on the frequencies is unknown so far. The presence of mini-PCIe slot for connecting the mains board PowerKit is generally an indirect sign of a factory overclock and overclocking orientation of …
