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 …

Official Presentation of CPU Cooler Thermaltake BigTyp Revo

Thermaltake, a world-known producer of thermal solutions, chassis and PSU, has officially presented its new CPU cooler modification, codenamed BigTyp Revo. This model has already been introduced at Computex 2012 where it got a lot of encouraging reviews and good prospects for the sale campaign. BigTyp Revo is considered to be an efficient solution for the cooling down of the around-socket spacing due to the horizontal radiator localization. Thermaltake representatives underline that their new product is compatible with Intel (LGA775/1155/1156/1366/2011) and AMD (Socket AM2(+)/AM3(+)/FM1) platforms.



BigTyp Revo framework consists of a compact radiator, low-noise fan, five heat pipes and a set of aluminum plates. The new model has got an aluminum base and is furnished with five copper heat pipes (6 mm each). Each of the pipes directly 'gets in touch' with the CPU surface, providing an outstanding heat removal power. The top of the radiator accommodates 120 mm fan which can be …

SilentiumPC Offers a Budgetary Fortis 2 XE1226 CPU Cooler

SilentiumPC, a comparatively ‘fresh’ player in the cooling market, has recently introduced a new CPU cooler for budget-oriented customers. Codenamed Fortis 2 XE1226, it features 130x95x155 mm dimensions and weighs 880 g. It is intended to support the majority of modern platforms, including Intel LGA 775/1366/2011/115x and AMD FM1/FM2/AM2/AM2+/AM3/AM3+.



The model is all about two-section aluminum heatspreader with a copper polished base, six U-shape heatpipes (6 mm each), and a single 120 mm fan DF12025. The latter is based on a hydraulic bearing and supports PWM technology. It is able to alter speed from the minimal 500 RPM to the maximal 1500 RPM. Herein, the ultimate noise level does not go beyond 22 dBA.


The DF12025 fan requires 12V rail and 0.2A current to be powered via 4-pin PWM connector. On the maximal rotational speed it produces 65 CFM airflow. Besides, testing results prove that this fan is estimated for about 50.000 hours of fail-proof operation.
