The overview of be quiet! Power Zone 650W (Z1-650W)

Let’s have a look at a power supply be quiet! of Power Zone series, designed for demanding gamers and enthusiasts. As you can see, there’s no way to avoid gamers, but how they will benefit from a new power supply but for the stability of its parameters, is absolutely unclear. The matter is that the devices’ characteristics for all the applications should be consistent with the declared specifications. So, the power supply we are currently reviewing is a quite good solution for every demanding user.


This series includes units with capacity from 650 to 1000 watts, which correspond to the 80 Plus Bronze certificate, support energy saving modes C6 and C7 of the Intel processors and have a low noise level.


Additionally, this series’ devices have a fully modular design, as well as a possibility to connect up to three case fans, and the propeller of the unit itself rotates for a few minutes after turning off the system. And, of course, the Power Zone models have excellent …

Next year TSMC will start manufacturing the first 20nm chips

The Taiwanese company TSMC confirmed its intention to start production of chips using 20 nm technological processes in 2013. However, for now the company does not plan its production on an industrial scale and will release the first chips in a limited quantities, giving them a total of 1% of production capacity. According to the head of the company, the mass production of semiconductor chips with this technology will not begin until 2014.



Meanwhile TSMC Company is going to produce only one version of the chip, which will be able to enter into the wide range of devices, from smart phones with low-power to high-performance graphics cards. For comparison, the Taiwanese company currently has four different output chips on 28-nm technology. These are 28LP (poly / SiON) for low-power low-cost chips, 28HPL (HKMG) for use in low power applications, 28HP (HKMG) for high-performance chips and 28HPM (HKMG). The latest version combines elements of high-performance chips with high efficiency …

HIS Adds 7770 iCooler to Its Graphics Cards Arsenal

A new graphics card of an average efficiency has appeared in the arsenal of HIS manufacturers.
