Yea until you read in the fin print that the unit is only rated for that output at 60F, oh wait they would not print that shit now would they. What we are saying is yes buy a PSU for your load (although you could just buy one and never replace it...) but make sure that you get one of high quality and with a good warranty. If you do plan to overclock you will need a good psu. At minimum just make sure that it has Active PFC.
