15b7b88253f36b08701442219fa9e030.pngPromoted at Computex 2012 global technical exhibition, Acer Aspire 5600U and 7600U PCs have finally been launched. The models supplemented the series of Acer's all-in-one solutions and offered a number of unmatched opportunities for customers. Among others, Aspire 5600U and Aspire 7600U computers are distinguished by an adjustable stand that doesn't have any mind-bending gismos. One should take into account that the newly launched products feature both similar and dissimilar characteristics.

First of all, these all-in-one PCs operate under the instruction of Windows 8 platform. They are equipped with 8GB DRAM of DDR3 type, hard drive of 1TB volume capacity, an integrated card reader, and a couple of USB 3.0 ports. Network facilities are realized via Wi-Fi and Bluetooth modules.

Secondly, both PCs have got quite different internal layout. Aspire 5600U is considered to be a more affordable solution based on up to Intel Core-i5 3110M version CPU (third generation of Ivy …

736c33a52b0a49ca704124a225914209.pngDespite the emergence of ultra-fast and voluminous SSD devices, data processing centers still require classical storage solutions. Hence, HGST, an affiliate company of Western Digital, decided to comply with the corporate demands by introducing budgetary hard drives entitled Ultrastar C10K1800. The new-comers are targeting exactly DPC-systems which are in need of high performance combined with fail-safe behavior.

HGST Ultrastar C10K1800 drives feature 2.5-inch form-factor and come in diverse capacity variations (from 300 GB to 1.8 TB). The models employ SAS interface with 12 Gb/sec throughput. It should be noted that designers involved the minimal amount of plates on the maximal possible tape density. The latter are thought to rotate with 10.520 RPM.

The implementation of only few plates provides for the reduction of power consumption; this is supposed to be a great benefit since the drives are estimated for a durable 24/7 operation. Thus, an average power consumption …

8a2048c85619ca7e468e8660ff4eac42.pngThe CORSAIR Company celebrates its 10th anniversary since the first release of power units. This manufacturer has already passed out 10 mln of power supply devices. To mark this great event out the company presented a snow-white CORSAIR RM1000i Special Edition model with white fan LED-lighting.

There will be only 100 samples available on sale, each having its own serial number. The overall CORSAIR RM1000i Special Edition power equals to 1,000 W, and the efficiency factor is 90% (the 80 PLUS Gold certification is received). By default it uses eight +12V virtual circuits with 40 А load capacity, though if necessary, one can put them into one powerful +12V channel with the max output capability of 1,000 W.

Needless to say, that the up-to-date circuit technology and top-grade element base are inside. A 135 mm fan, based on FDB bearings, is installed to provide active cooling. Also the CORSAIR RM1000i Special Edition cable system is entirely module and possesses handy line …
