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 …

Fractal Design has announced Define R4 hull

In nearly two years after the announcement of the hull Define R3, Fractal Design Company announced the release of its ideological successor. New, executed in the same minimalist style, has received the designation Define R4.

The hull is designed to install motherboard sizes ATX, Micro ATX and Mini ATX, and eight expansion cards. Define R4 design provides for two external 5.25-inch bay size, as well as ten internal, eight — to set the size 3.5-inch HDD, two — for the installation of SSD size 2.5 inches.

As the creators say, inside Define R4 can be used CPU coolers up to 170 cm, power supplies up to 270 cm, and graphics up to 295 or 430 mm (respectively, with basket for the HDD, and without it). As for the cooling system, it involves the installation of up to seven fans: two front, one rear, two top, one bottom and one side. The package includes two fans Silent Series R2, front and rear. Both are characterized by a diameter of 140 mm and speed 1000 r / min. Interestingly, …

New Thunderbolt Edition Graphics Card from Zotac

Zotac, a well-known designer of graphics solutions, has developed a unique in design graphics card. Entitled Zotac GeForce GTX 660 Thunderbolt, this card is heading a new Thunderbolt Edition series that is considered to be a more affordable product than Extreme series. The novice is equipped with an original PCB and an effective cooling system.

Zotac GeForce GTX 660 Thunderbolt is primarily characterized by a unique cooling system that consists of a large aluminum heatsink, three cooper heat pipes which get in contact with GPU from one side, and a couple of 100 mm fans. It should be mentioned that Zotac developers have realized a dedicated Eclean technology in their card that enables a hassle-free demounting of fans and top cover with the purpose of cleaning the cooler from dust.

GK106 chip, designed on Kepler architecture under 28 nm technological process, functions as the basic element in GeForce GTX 660 Thunderbolt card. It involves 960 CUDA cores and operates at 980 MHz …
