still abit weary of that psu since you didnt give a brand name... Im sure there are crummy psus out there that claim to be amd intel approved. One idea to check the quality of the supply is how heavy it is. If its super light like a tin can then it might be a lower quality supply. If its heavier usualy means its a good supply. Just a general guideline though
As for the cooling what is your case installed fan layout like. cpu heatsink being used. etc.
