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 …

Gigabyte Readies Entry-Level Graphics Card GV-N640D5-2GI

Gigabyte is going to introduce one more entry-level graphics solution that corresponds to the updated Nvidia GeForce GT 640 series. Entitled Gigabyte GeForce GT 640 (GV-N640D5-2GI), the card employs GK107 GPU, running at 1046 MHz frequency instead of the preceding 900 MHz. The core, developed under 28 technological process, utilizes 384 CUDA cores.



It’s necessary to underline that the new-comer differs by the availability of 2 GB memory, whereas all etalon models take 1 GB only. Memory is represented by 64-bit GDDR5 chips that run at 5010 MHz effective frequency, if compared with 1800 MHz frequency that DDR3 modules demonstrate.


GV-N640D5-2GI comes with an improved design of PCB where a brand Ultra Durable 2 concept has been incorporated. This concept implies the employment of a high-quality hardware base, involving durable solid-state capacitors, transistors with low channel resistance RDS (on), and ferrite throttles with reduced power loss. Traditionally, the model …

Enermax Unleashes PSU Platimax 1350W

Enermax Technology Corp., a leading supplier of power supply units, chassis, and other PC hardware, announces the release of powerful PSU, codenamed Platimax 1350W. This model is primarily targeting enthusiasts and professionals who appreciate reliability and endurance in the 'toughest' conditions. The PSU is destined to manage up to 1350W loading at +12V line, with the peak loading of 1600W.



All potential customers will be drawn by the utmost efficiency that fluctuates within the measures of 89%-94%. Such outstanding characteristics allowed the product to receive general acknowledgement and 80 Plus Platinum certificate. Platimax 1350W model employs good quality capacitors and features removable cable scheme. The manufacturer offers also five-year limited warranty along with PSU.


Platimax 1350W is equipped with ten- and 12-contact sockets for the future graphics cards and CPU generations, as well as, with a dedicated security system protecting the device from emergency …
