More than likely you are maxing out your psu's +12v rail which is causing instability.
What is the +12v amplitude?
It'll be printed on the side of the psu, if it's less than 26A then look for a new one.
Another way to check is to put your cpu back to stock settings, if your graphics card overclocks no problem then your psu is too underpowered.
500W means nothing, there are ways that manufacturer's use to overinflate their ratings.

If you need an alternative psu, I'd suggest either of these:

my +12v is always 11.82 what about upping the M.H.C in bios to give gpu a bit more juice.
