Your PSU is fine. Overclock all you want.

Hi - A quality 530w unit is more than enough to run the sys and OC. The
issue you may have is that Raidmax(made by Andyson, a bottom feeding oem)
is a "poor quality" PSU, and I don't know how many watts & 12v rail(s) amps
it can actually deliver.

Given that your system can run fine on a quality 430w unit,
then try the gtx 660 with that psu, and start saving to
upgrade to a quality brand/model.
