That psu doesn't have i think a 6 or 6+2 pin pci-e connector, and its from a unknown brand, so no...that build had a 6670(which doesn't require external pci-e power) so your best bet is a 7750 AMD 1GB DDR5 or buy a new cheap but decent psu like the corsair builder 430w + the 660 gtx.

Hey,

It should be ok, as long as the PSU is a good quality unit. If its the stock Cyberpower one then it might not be of the best quality. Which 500watt psu do you have (brand name, model)? If its a good quality unit and has the required 6pin connectors then you will be fine.
Also what are the other components in your system?

Hope this helps!

Well your PSU is not of very good quality as it is the stock cyberpower unit, and the fact that it lacks the 6 pin connectors is not good either. You could use an adapter such as a 4pin molex to 6pin, but its not recommended. The best option would be to get a new PSU to go along with the gtx660.

Some good brands are: antec, corsair, seasonic, but there are many more good ones out there.

I would get a 500 watt PSU, as it should be more than enough, but if you plan for future upgrades you could go for a 650 watt.

Yes. In the first and last picture, they used high end CPUs which they OC to death. Your power consumption will be closer to the second picture.
