I wouldn't suggest using that PSU at all. It was built using very low quality components and has the potential to damage other parts in the computer.

I'm using it with a 6770 card and it is overclocked and every thing is good and 6770 uses more than 108 watt

Really went for the cheapest power supply you could find couldn't you? The Cooler Master Extreme II 525 is actually a 475W PSU, but not even one that can do its labeled wattage. The "525" hasn't been reviewed yet, but the "475" has, it wasn't good.

Efficiency is abysmal, vreg is abysmal and it dropped below the allowed limit at 80% load, the only part of the unit that wasn't abysmal was its ripple suppression which only ranged from below average to bad.

A GTX 760 needs 170W, thats going to be a pretty big jump in power consumption for your system. I would definitely advise against it, and if you decide to continue with your cheapo PSU don't be surprised if you start seeing instability with the new card, you will get significant voltage drop at full load.

I echo Gabe's sentiment at the end of the article

We think it is simply ridiculous that in this day and age there are still well-known brands labeling power supplies with fake wattages.

Ok .....will a 475 psu be enough ?

When choosing a PSU it's not just about the wattage. You need to look at quality. Low quality parts have problem like por voltage regulation and ripple, these problems will cause system instability and you also run a high risk of damaging everything that psu is attached to. Is saving a few bucks on the PSU really worth having to replace multiple components because your PSU took them out? When low quality PSU's fail they often don't die alone. In the end it's your choice if you want to gamble on it or not. But you can't say you weren't warned.

The 475W PSU you have will not be, no.
