How many modules this one can do? I just bought it.

To be honest I have trouble understanding why ~2W/chip = ~40W/board x 15 = ~600W isn't good enough for mentioned PSU (720W).
Please note that in this case I am not asking to save money by choosing PSU with less efficiency certification standard (80 Plus Bronze in this case), but ask is it going to work.
