A w a yuan gold efficiency bone gamma G800 power evaluation
Power supply channel in July 18th at this year’s Taipei computer show Cougar exhibited their a high-end high efficiency power products — GX800. The power supply adopts modular wire design, Samsung AA-PB8NC6M battery through the 80Plus gold certification, the highest conversion efficiency of more than 90%. Because now80Plus promotion success, let PC power supply is becoming more and more obvious, but also the power saving technology is more and more advanced, more and more popular, so do not arrive 3 years in between, there have been a lot of gold efficiency power floods the market, this is inconceivable 3 years ago.
However, the gold medal power while having excellent efficiency, but the game player also need to spend large sums of money as the price, it makes feel the loss outweighs the gain. However, bone gamma GX800power is changed” gold gold” impression, the price of 799 yuan thermal sob unceasingly, gold efficiency power each tile is insufficient 1 yuan price, in addition to praise the cougar ice besides courage, also not recognized, gold power price war has begun.
The word does not say more, Sony PCGA-BP2S battery here we have to work together to find the cougar bone gamma this rated power800 Watt GX800gold power.
In fact, the bone gamma GX Series Gold power, since the end of 10, has been officially released, but only in Europe and the United States market sales, until recently, GX series power before formally entered the Chinese mainland market.
The power supply design, inherited the cougar bone gamma consistent style, matte painting, gold decoration. And in the side of the power supply and the fan front are printed with ” Jaguar” Gougar LOGO.
The power of the rated power of 800W, the4 12V output, each current limiting were 22A,22A,24A and 24A, the maximum output power of792W, so12V power output capacity very tough, for high power card and 12V overloaded state, have very good support capacity.
The power supply adopts modular design, and the use of plastic flat wire, for game player chassis line has a very good help.
Power supply adopts module design of power wire, but also with primary wire, Sony VAIO PCG-VX89 Series battery and the use of snakeskin wire wrap. In addition, the power supply module interface with color logo, as well as the text labels, so as not to connection errors.
Power distribution wire is more rich, in addition to a motherboard24Pin interface,1 8Pin,1 4+4Pin and 1 4Pin three CPU4 6+2Pin interface, PCI-E interface,6 D interface,10 SATA interface and1floppy disk interface. Can meet many hard disk and graphics needs of game player.
For a power supply, static testing is not enough, because in actual use, we supply may not” stand stable” condition, the slowly rising or falling power load, but often in different load down switch. For example, two power cards in different screen calculation ( simple and complex ), in our moments from the game to cut back the desktop ( or cut back into the game ), Toshiba TS-2450L battery will let the momentary power load variation. If the power is of poor quality, can appear offline. Therefore, we here have a look, the power dynamic test results.
In the dynamic test, we will supply from 0.2KHz to10KHz frequency adjustment, and through the test we find, in the 200Hz frequency, voltage is about 200mV, but in more than 1KHz after the ripple wave type has been unable to discern. And it is worth saying is, power from 200Hz frequency began to whistle. And this can be seen in the dynamic performance of the power supply, standard. Of course it may also cost control related with power itself.
