Incredibly Efficient Power Supplies Coming

I've been researching PC equipment to build the cheapest, fastest, and most efficient DIY NAS device possible. It looks like I'm going to want to wait a while on the power supply. My system shouldn't need more than a 300 watt supply. Check out the specs on this reference design for a 250 watt supply from NXP. If you spend some time thumbing around on 80plus.org comparing efficiency curves, you'll find those are incredible numbers. Almost 93% efficient at 20% load! That is insanely good.

The application notes for building these supplies came out 8 days ago so it is probably still a few months before we see some products.
