Chieftec has recently introduced four new power supply units, replenishing Smart series. The series is supplemented by GPS-400A8, GPS-500A8, GPS-600A8 and GPS-700A8 models. It should be stated that all the models are targeted only at European customers, since their specifications allow the connection only with 220V-230V networks. Those PSUs are also directed at average customers rather than gamers due to the company's plans to expand its horizons.



The major distinction between the upcoming models is their power that fluctuates in the measures of 400W and 700W. All PSUs are developed in PS2 form-factor and correspond to the ATX 2.3 international standard. Their casings have got black coloring and are characterized by non-modular design. The length of cables reaches 80 cm that is enough for the connection with various devices. Moreover, efficiency level of Smart series exceeds 80%. At the same time, all the models conform to the major environmental guidelines.

The efforts of Gigabyte engineers culminated in the release of the Radeon HD 7970 Super Overclock, also known as GV-R797SO-3GD. This is a monstrous construction with height of 64 mm (3.5 expansion slots) and a cooling system WindForce 5X. As well as preparing to be released GeForce GTX 680 SOC, the new adapter uses a five high-speed (> 4000 rev / min) fan size of 40 mm, copper evaporation chamber, and five copper heat pipes.



WindForce 5X – is one of the most expensive VGA-coolers, except for models with water blocks and liquid cooling system. It will allow to overclock Gigabyte GV-R797SO-3GD up to frequencies of 1155/7620 MHz. However, neither the temperature nor the noise performance of video card can be considered satisfactory: 85 degrees under load and 91 ° C for overclocking with increased voltage, and 8000 rpm in a heavy-duty (1185 MHz, 1.375 V) explains the situation.


Printed circuit board Radeon HD 7970 SOC is reinforced with five polymer capacitors NEC / …
