I purchased a hd 7750 for my 300w psu for its low power consumption but the one I notice I mistaken purchased a slightly over locked one from 800 to 820 MHz is this little enough to where it should still work
 
Solution
try it, at worse if it's unstable (restarts/crashes) you can downclock it from amd overdrive instead to say... 700-750mhz instead to reduce power draw.
