If it 90% efficient then to supply 277W @ 12VDC requires 308W @ 120VAC.

Talking about serious PSU, here. The kind that cost more than HF chips. Grin

I was not aware that commercial PSU had reached a 90%+ efficiency on a ~100% load.
Seems to be acheived, and not that expensive, so I'll just shut up.
