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 …

Chieftec Showcases Five New PSUs from Navitas Series

Chieftec, one of the largest German hardware manufacturers, has recently introduced a new series of power supply units, codenamed Navitas. The series is represented by 5 models: GPM-650C with 650W nominal power, GPM-750C with 750W nominal power, GPM-850C with 850W nominal power, GPM-1000C with 1000W nominal power, and GPM-1250C with 1250W nominal power correspondingly. All the products have won 80Plus Gold certificate, due to more than 90% efficiency in the high workloads.

Chieftec Navitas PSUs correspond to ATX12V v2.3 standard and support Intel Core 4th gen. processors that require little current strength on +12V rail in sleep mode. The models also support active power-factor correction option to provide for the maximal stability during operation. They are equipped with a composite cable system and a single +12V rail, estimated for the maximal current from 54 A to 104 A (this index depends on the unit’s power).

All five units are cooled down by 140 mm fans with PWM …

Transcend Releases SSD320 with SATA III Interface

Transcend has introduced a series of new 2.5'' solid-state drives, codenamed SSD320. The new product supports SATA III 6 Gb/sec standards, and is notable for the outstanding data transfer speed, as well as, reliability. SSD320 is based on SandForce SF-2281 controller of the second generation which adds to the overall performance.

Transcend SSD320 series will include drives of various volume capacities, starting from 64 GB and finishing with 256 GB. These models employ MLC NAND flash-memory chips. In addition, those SSDs support error correction technology. Transcend has taken care of its new series and promoted for the unmatched performance and showings. SSD320 ensures quick download of programs and practically instantaneous system response while working with complicated graphic material or multimedia applications. The devices are capable to achieve the maximal reading speed of 560 Mb/sec, and the maximal writing speed of 530 Mb/sec. Random writing speed (4K) equals to 87000 …
