Will my power supply cope with a better graphics card, if so what one?

Hi
I was wondering if I could upgrade my graphics card to something better but not too power demanding since I only have a 450 watt psu.
My specs are :
GPU: 2048MB AMD Radeon HD 6670
PSU: Corsair VS450 450 Watt PSU
RAM: 8GB
CPU: AMD FX-6200
HDD: 932GB HITACHI HUA721010KLA330 ATA Device (SATA)
I'm worried that if I get a 7770(or better) it might fry my system and also my CPU is very power demanding.

Maybe a HD 6870?

Hi - A 7770 will run fine on that PSU, A 7850 will also run on it, as well as
gtx650ti or gtx 660

Are you sure? I thought it would be ok but my processor uses so much energy compaired to a i3 or something so it might not be enough power for a new GPU?

Yes, sure.
7770 uses very little power and while the 7850 does use more your
PSU will run it fine. The key pwr figure is not the total wattage, it's
the amps available on the +12v rail. Your PSU has 34a on the +12v rail,
while those cards need 19a & 21a on the +12v rail and that's a tot
systen requirement not just the gpu.
GPU mfg's overstate power needs for their cards to allow for PSU's
that don't deliver their publ specs and to allow for older PSU designs
that don't have a lot of the total amperage allocated to the +12v rail(s).
As I stated above your vs450 has more than enough +12v amps
for the cards you might be considering.

ok thanks I get a 7770!
