I think you are incorrect. The 80 Plus Efficiency ratings are at 20%, 50% and 100% load, not just "peak".

He's absolutely right ...

Your 80%, 1200W PS generates 240W of heat powering your 150W system.

...except for this part. An oversized power supply is wasteful, but not this wasteful.

20% of 1200W = 240W. Efficiency is measured as % of rated (i.e. peak) load, not of actual load.

No, it's not.
