Enermax Revolution87+ 850W Gold

Source Enermax Revolution87 + completely exhausted all possibilities of optimization of DC, but that its advantages far from over. Since the DC circuit is already at the top of its technology are engineers Enermax focused on developing more efficient transformer. Thus a layout " Dynamic Hybrid Transformer Topology "Which can be divided into three main parts.

First resonant dynamic transformer array

It is based on a highly efficient resonant topology that is used as LCD monitors. The main noticeable change is added to the PCB resonant choke.

2 dynamic voltage increase transformation
First, the capacitors are charged by alternating current (AC) from the wall, with the help of which ensure a continuous supply AC DC power transformers by PC. Hitherto, capacitors charged statically, so that there at low sampling to excessive losses. Enermax series capacitors are charged Revolution87 + dynamic voltage - depending on the desired system performance. With the resources Enermax significantly increase its effectiveness.

Third dynamic frequency transformation
Transformers optimize alternating current up or down. During this time you will lose some power. Companies Enermax managed to optimize this process using dynamic frequencies. Transformers operate with a wider frequency range in accordance with the variable consumption of system components. With the resources Enermax significantly reduce their energy loss.

Source Enermax Revolution87 + you through the installation please modular cabling . Does it even so cleverly done by the cables, which uses each computer has fixed. This allows you to eliminate the clutter in the closet and better optimize airflow. The fact that it is a source of future needless doubt on his body, moreover, see 10/12pinové connectors for future energy-consuming components.

In addition to the incredible performance takes Enermax Revolution87 + peak efficiency Which in terms of network 230 in the range 90-93%. Moreover, it requires no minimum order, so it is a great tool for a variety of hybrid CPU/GPU Solutions. With an improved and highly efficient 5V standby (+5 VSB) circuit ensures, in combination with ErP/EuP Lot 6 motherboard less than 1 W consumption in standby mode . Cooling from 13.9 cm fan with patented Twister Bearing Technology then performs efficient and ultra quiet cooling, backed by long life fan. He spins at low loads only very slowly, so it is very quiet - as another advantage of high efficiency, minimal waste heat.

Source foursome includes 12 branches of power, the maximum individual load current is 30 A, the combined load of at most the sum of 70 A, with absolutely minimal ripple. Enermax simply Revolution87 + premium source, as evidenced, for example, that despite the ostensible maximum power of 850 W is capable of over sixty seconds to deliver 935 W. As well as a complete set Japanese electrolytic capacitors, which are able to operate up to 105 ° C ambient temperature.

Among other interesting functionalities can be named SpeedGuard fan speed control, which caters innovative fuzzy logic for optimal cooling and minimum noise. Function HeatGuard takes care and spin the fan 30 to 60 seconds after turning off the computer for longer service life of components. CordGuard ensures the power cord connected to unintentional removal, for example when cleaning. And last, SafeGuard includes a broad set of protections against fluctuations and surges in the network.
