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 …

Gigabyte Intros Affordable GA-B85M-D2V Plus Mainboard

Micro-ATX/mini-ITX mainboards keep on capturing the market due to the augmentation of small-sized PC platforms. Against this background, Gigabyte is constantly enlarging its portfolio of compact motherboards. Take GA-B85M-D2V Plus alone. This model might boast an optimized functional and an improved audio subsystem combined with a sleek design and a range of protection doo-dads.



Gigabyte GA-B85M-D2V Plus takes Intel B85 chipset as the basis. The latter supports Socket LGA1150 CPUs (Pentium, Celeron, Intel Core). The company’s designers employed an improved fiberglass mode of superposition on elaboration of PCB textolite; this is called to protect the board from humidity, electrostatic discharge and voltage instability.


The board’s layout supports Ultra Durable 4 Plus design that involves only high-quality components, like solid-state capacitors, transistors with low open channel resistance. The PCB is equipped with two DIMM slots ready for 16 GB of DDR3 memory (1600 …

Micron to Carry Out the Production of TLC Memory Next Year

Memory market, similar to other industries, undergoes certain changes and updates from time to time. Therefore, memory manufacturers are currently trying to comply their production with two major tendencies: considerable drop in demand for RAM, employed basically in desktop PCs, and simultaneous growth of demand for solid-state drives, employed in compact tablets and mobile devices. Besides, the latter is developed at lightning speed.



Micron, one of the leading memory manufacturers, feels like no one else all the changes and fluctuations in the market. Its quarterly reports witness about the relentless drop in demand for DRAM (9% drop at average) for the report period. At the same time, increase in SSD segment is estimated at 5% at average. Sales volume of NOR memory type did not outlive serious changes.


According to the preliminary data, Micron is going to carry out the production of memory on TLC microchips, manufactured under 20 nm technological process. The assumed …
