Yes, the brand matters. There are lots of PSU's out there that not only won't deliver
their specs, but can damage other components when they die or burn up.
Since I know nothing of this brand, I personally wouldn't touch it.

Maybe some other users will be familiar and comment on it.

Hi - Corsair is a well known brand and their publ specs can be trusted to be
true. Unless you plan on running 2 GTX660's in SLI, you don't need anywhere
near a 750w unit.

You should save some money and look for a 500 -550w unit (even a good 450
will run your system). You already found a good brand, others are Seasonic, XFX,
Silverstone, Antec, & a few more.

But can my current PSU power it?:http://www.emag.ro/sursa-floston-fl500-extra-500w-neagr...


Yes, if it is a true 500w PSU. Another brand I'm not familiar with. If
it's anywhere close to a 500w unit it will power your system with a GTX660.
Try it, keep a close eye on it. if you get random restarts, etc. then you'll need
to upgrade, but you might be OK with it.

Hi - like i said above, try it with the gtx660. The 660 doesn't require a lot of power.
Yes, more than a7750. But, your PSU has a pcie connector, so hook up the
660, I think you'll be OK.

One more question.If the PSU is not good enough will it destroy my PC?

Hi - it shouldn't, but you need to check your documentation on it or contact the place
you bought it from. You need to know what protections are built in. A good PSU will
have features that will shut the PSU off if it gets too hot, if the voltage goes out of spec,
and others.

The specs list 24amps on the +12v rail, that is enough to power
a system with a gtx660, but not a lot of headroom.

So, if it doesn't have protection features it could damage other components. However, you've been running a 7750 on it and a gtx660 doesn't use much more power. If you
weren't having problems with the PSU running a 7750, you should be OK with
a gtx660.

Not all PSU's have sufficient protections built in. That's one of the main reasons to
go with a known to be good brand. I still think you are OK to go with a gtx660.
But, your PSU is an older design, a modern decent 500w PSU would have a lot
more +12v amps than 24. If I were you, I'd get the 660 and save some $$ to
upgrade your PSU.
