Should be enough, don't know which GPU you had before but that one uses very little power.

It's going to work, but if yo someday can upgrade to a 400W psu would be great to be on the safe side of things

65 watt processor
20 watt video card
About a 150 watt PC you should be fine.

I agree, I only needed 520w, but I went on the safe side and got a 750w

Yes, PSU not always are able to supply the power they spec all of the time and specially in cases like his that the upgrade is in an existing build with a used PSU that maybe is giving a less power anyway due to use (this is more normal than people think). And a lot of staff than can drew more power than is supposed to do

Thats why also in the officials specs for this 6450 2Gb says that the recommended is a 400w supply.
