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 …

Presentation of Workstations and Graphics Servers of ESC Series

Asus has recently presented workstations and graphics servers of the second generation ESC series. The new series includes ESC4000 G2, ESC1000 G2 and ESC2000 G2 models which serve the function of high-end platforms for GPGPU applications in such fields as medical research, financial modeling, computer-aided design, animation and 3D-rendering. The systems can boast a wide spectrum of options and outstanding integration; they are able to support high-end Intel processors and four graphics cards, and are equipped with the efficient PSU and expansion slots PCI Express 3.0x16.



All three models of ESC series are furnished with high-quality PSU which correspond to the 80Plus standard. Thereby, each of the models boasts energy-saving facilities: ESC1000 G2 and ESC2000 G2 go with a single PSU of 80Plus Gold standard in 1350 W capacity; ESC4000 G2 goes with two PSU of 80 Plus Platinum standard in 1620 W capacity (one of them is an emergency unit in case of troubles with the other unit). … …

Thermaltake Enters the Market with NiC L31 and L32 CPU Coolers

Thermaltake Technology has just started shipping a pair of budgetary CPU coolers from NiC series. Entitled NiC L31 and NiC L32, these two models are compatible with all updated Intel and AMD platform motherboards. In keeping with the manufacturer, the new-comers will not obstruct the mounting of memory modules, due to their well-considered framework. Hence, they consist of small-sized heatsinks, three U-shape heatpipes (8 mm), and a base that is in direct contact with the CPU.



The first model, NiC L31 (codename: CL-P001-AL12RE-A), features 140x128x40 mm dimensions and weighs 530 g. The integrated 120 mm fan might operate in various speed modes – from 500 RPM to 1800 RPM – thanks to the support for PWM technology. It produces up to 70.99 CFM and dissipates up to 160 W power.


At the same time, at the minimal speed mode it generates only 18 dB noise, however at the ultimate rotations this index rises to 34.8 dB. According to the results of multiple tests, this fan is …
