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 …

Toshiba to Release Entry-Level A100 Solid-State Drive

Toshiba is about to release a 2.5-inch SSD, entitled A100. The entry-level model is based on TLC NAND flash memory chips (15 nm) with the cooperation of SLC cache memory. Traditionally, the drive employs SATA 6 Gb/sec interface and takes Toshiba TC58NC1010 chip as a controller.



The greenhorn is available in two versions: 120 GB and 140 GB (dimensions: 100x69.85x7 mm). The couple is an optimal choice for home & office PCs, thanks to the incorporation of power-efficient, high-performance and shock-proof technologies. The drives’ maximal data transfer speed on sequential operations makes up 550 MB/sec & 480 MB/sec (read/write). The maximal data transfer speed on random operations (4K) achieves 87.000 IOPS & 82.000 IOPS correspondingly.


Toshiba A100 solid-state drives are known to support NCQ, TRIM and S.M.A.R.T. technologies. An estimated MTBF index equals to 1.5 million hours. The 120 GB item might endure 30 TB of written information, while the 240 GB item allows for 60 TB …

Shuttle Offers a New Stylish NAS Storage Omninas KD22

Shuttle, an eminent Taiwanese developer of mini-PCs and barebone-systems, replenishes its production line with a new NAS, entitled Omninas KD22. The storage features a stylish, solid aluminum case, painted in white, and a large blue button that is responsible for the hot swapping of the drives. Generally, the case can accommodate a pair of 3.5-inch (or 2.5-inch) SATA drives, which support such configurations as JBOD and RAID 0/1.



The heart of Omninas KD22 is Marvell 88F6707 processor that runs at 1.2 GHz. The storage is furnished with 512 MB RAM and might offer up to 8TB of disc space. Being primarily a network-attached storage, the product is able to serve as a media-server as well, supporting iTunes, DLNA, BT, FTP server and print server. Additionally, there is a possibility for several different ways of local data transfer.


In order to fully realize an operational potential, Shuttle equips the model with a card-reader for SD cards with automatic copying options, three …
